Posts Tagged ‘CO2 pistols’

Today, we’ll look at the velocity of the Gamo P-25 air pistol, and something interesting that happened. Normally, I report on the velocity of 3 or 4 pellets and leave it at that, but a strange thing happened with the first CO2 cartridge in the test pistol.
I didn’t screw the piercing screw deep enough into the CO2 cartridge, resulting in the gas flow being hindered. I’ve experienced this a few times in the past, but this time it was very pronounced. After each shot, there was a period of time that ranged from 5 to 10 seconds, during which the gas flowed audibly from the cartridge into the gun’s valve. It sounded like a leak in the gun, but I noticed it only lasted a few seconds before stopping, so it wasn’t venting to the outside. It was the gas flowing from the cartridge into the gun’s valve, where it would be used for the next shot.
Shooting the pistol in the rapid-fire mode proved impossible with this first cartridge. The first shot went out at the normal velocity, and shot 2…fired immediately after the first shot…clocked 88 f.p.s. through the chronograph.
It was my fault
So, I screwed the piercing screw much deeper into the next cartridge. Problem solved! Don’t be tentative when piercing a cartridge in this pistol. Do it like you mean it. After I pierced the second cartridge correctly, the pistol performed exactly as expected. Rapid-fire worked as you would expect, and the gun kept up with my trigger finger.
The first pellet I tested was the RWS Hobby. Weighing 7 grains, the all-lead Hobby pellet tells me so much about an airgun’s powerplant. For starters, it tells me what needs to be done to get the 425 f.p.s. velocity that’s claimed for the gun.
Hobbys averaged 353 f.p.s. in the P-25. They ranged from a low of 333 to a high of 379 f.p.s., and some of that large variance may be due to the gas flow problem I mentioned. At the average velocity, Hobbys were generating 1.94 foot-pounds of muzzle energy.
The Hobbys told me what I wanted to know. This pistol wasn’t going to get its rated velocity with a lead pellet. So, I needed to try it with a lead-free pellet; and since this is a Gamo gun, the Gamo Raptor PBA sounded like a good selection.
The Raptor PBA pellet is made from metal that’s harder than lead. It weighs 5.4 grains and will generally boost the velocity of an airgun above what a lead pellet will, though the hardness of the metal actually slows it down sometimes. But in the P-25, the Raptor PBAs worked just fine. They averaged 412 f.p.s. and ranged from a low of 395 to a high of 432 f.p.s. So, the ads are right on the money. At the average velocity, this pellet generates 2.04 foot-pounds of energy.
Next up were the lead Gamo Match wadcutters. They weigh 7.56 grains and are sometimes quite accurate in some guns. In the P-25, they averaged 348 f.p.s. with a spread from 329 to 357 f.p.s. The average energy was 2.03 foot-pounds. This will be a pellet to try in the accuracy test.
Crosman Premier 7.9-grain lites
The last pellet I tested was the 7.9-grain Crosman Premier lite. They fit in the circular clips of the magazine rather easily, which caused some concern they might fall out; but the way the magazine is designed, only 2 pellets at a time are exposed in its clip. So the worry was for nothing.
Premiers averaged 344 f.p.s. in the P-25, with a spread from 330 to 360 f.p.s. At the average velocity, they generate 2.08 foot-pounds at the muzzle.
The double-action trigger-pull broke at exactly 8-1/2 lbs., which is light for a DA pull. On single-action, it broke under 4 lbs., with a huge creep at 2-1/2 lbs. That creep is consistent and lets you know when the gun is ready to fire.
While I got just 50 shots on the first cartridge, I got more with the second one. Besides the velocity testing, I did another test with an entire cartridge, just to see how the pistol operates in the rapid-fire mode. So, the correct piercing is very important. I fired an entire cartridge, just to see how the pistol handled. Everything worked smoothly until shot 48, when the blowback failed for the first time. After that, the blowback would work if I waited long enough between shots, but not if I shot rapidly. However, if you allow time for the gun to warm up, it keeps right on shooting.
There are certainly 75 or more powerful shots in the gun if you allow the gun to rest between shots. The blowback will work reliably past shot 50, as long as time is taken between shots. Shoot fast, however, and the gun cools too much and wastes gas.
Impressions so far
So far, I like the P-25. I like its simplicity and the light single-action trigger. If it’s also accurate, this might be a best buy.

Okay, now for something a little different. The Gamo P-25 air pistol is a 16-shot pellet pistol with blowback and a rifled barrel. This pistol operates on CO2, and the 12-gram cartridge is hidden inside the grip.
Normally, a gun like this is a BB gun, but this time there’s a rifled barrel — and the chance to shoot many different lead pellets, plus a trigger that’s both single-action and double action. Because of the blowback action, you’re going to shoot this gun single-action most of the time.
The P-25 is a 21st century handgun is every respect. It’s nearly all synthetic, entirely black and the grip is fat, as though enclosing a double-stacked magazine. The fixed sights feature three white dots — like night sights, but without tritium inserts. Align the three dots and put the center dot over your target…and I assume you’ll have minute-of-soda-can accuracy at 25 feet. We’ll find out more about that when we test the pistol for accuracy.
I like the fact that this pistol comes with blowback. That gives a realistic feel to each shot, which makes this a good trainer for maintaining firearms proficiency. When we get to the accuracy test, I’ll let Edith shoot the pistol and give her assessment, too. The gun I’m testing is serial number 12F31301.
The P-25 is a large pistol. Maybe it looks like a pocket pistol in the photograph above, but in person it’s larger than an M1911A1 in all ways, save length.
The trigger is very strange. Usually a single-stage trigger is crisper and lighter than a 2-stage trigger, but this one isn’t. While the pull weight isn’t that heavy, there’s a country mile of takeup even in the single-stage mode — i.e., when the hammer is already cocked. Once the takeup is done, though, the trigger breaks cleanly enough. It isn’t exactly crisp, but it is light and very predictable. I don’t think I’ll have any trouble with it.
The double-action pull is relatively light, though you’ll only feel it on the first shot after installing the magazine. Once the gun fires, the slide blows back, cocking the hammer for every successive shot.
The trigger blade is very wide. I find that gives a nice feel to the pull when I’m trying to control the let-off or point at which the trigger breaks.
The safety is another matter. It’s one of those Euro-lawyer safeties that have a center switch that’s pulled back before the lever can be moved. There’s no way to operate this kind of safety with one hand. It blocks the trigger when its on.
The magazine is a stick type with two circular pellet clips — one on either end. It’s a drop-free design, and the release button is on the left front of the grip frame, where a right-handed shooter expects it to be. The mag has to be ejected and turned around for the second 8 shots.
This gun runs on CO2. The manufacturer says it gets up to 425 f.p.s. with pellets, and we will test that for you in Part 2. The cartridge is hidden in the grip, and this time the enclosure is different. The bottom rear of the grip is pulled away from the rest of the grip, and two-thirds of the CO2 compartment is exposed. When the cartridge is installed, a conventional piercing screw tensions and pierces the cartridge. Don’t forget to put a drop of Crosman Pellgunoil on the tip of each new cartridge as it’s installed. That will keep your gun sealed for many years.
The P-25 is moderately heavy, at 29 oz., so the blowback action causes a fair amount of bounce. It feels not much different than a medium-weight .22 rimfire pistol shooting standard-speed long rifle rounds.
The barrel is rifled steel. That gives me some hope that this pistol will also be accurate. If the blowback feature doesn’t use too much gas, the P-25 could turn out to be a very nice plinking air pistol.
All things considered, at this point the Gamo P-25 air pistol looks like a good one. I hope it delivers on that promise.

The new Umarex P-08 BB pistol is a stunning copy of the firearm.
Well, today’s the day we see how this Umarex P-08 BB pistol shoots. As you know, I think this pistol is a big deal because people have been asking for it for years. And, yes, I’m aware that there are Asian BB pistols in the P-08 style that are supposedly all-metal and have blowback with realistic toggle action. But are YOU aware that sometimes those Asian websites lie about what they have? Some of those guns don’t exist, and images are shown to see if there’s enough interest to warrant the development cost.
Think about that before you jump on the bandwagon and criticize a real product. You may be comparing it to something that doesn’t exist.
Back to the gun at hand — the Umarex P-08 is a double-action-only handgun, and I think you’ll understand what that means by now. If you don’t, click on the link to Part 2 above and look at the picture of the revolver. Some of you mentioned that the revolver also advances the cylinder with the trigger in addition to cocking the hammer spring…and you’re right. That does add some resistance to the total effort required. However, I find that it doesn’t add as much as you might think — perhaps 10 percent or so. The majority of the effort to pull the trigger is dedicated to compressing that powerful hammer or striker spring.
I learned in this test that I cannot control the P-08 double-action trigger as well as I thought. Of course, a single-action trigger that just breaks at a few pounds is much easier, but a week ago I shot a 4-inch, 7-shot group at 45 feet with my carry gun, which is a Micro Desert Eagle that’s DAO in .380 ACP. That pistol is lightweight and has a relatively snappy recoil, but the double-action trigger-pull is smooth all the way through. So, I can put the sights on target and hold them there through what is perhaps an 11- or 12-lb. pull.
That is what I was expecting to happen with this BB pistol, but it didn’t. Not quite. Oh, the trigger-pull does stack at the end, and it isn’t as heavy overall as the triggers in my firearms, but the last bit of effort seems to increase or rise a lot more. That rise is what I find difficult to control, and you’ll see the results today. The other problem is that the trigger comes very far back when pulled. It releases very close to the back of the triggerguard, and that’s the spot where the strength leaves your fingers.
This is a BB pistol, so I shot at 15 feet, which is the normal BB gun distance. You may think that’s too close for a target pistol, but wait until you see the results of the test. It turns out that 15 feet is a very good distance to shoot, for reasons I will address in a little bit.
I shot at a target pasted to the face of a Winchester Airgun Target Cube. I’m reporting on this target cube in all of the BB gun tests I do instead of writing a special blog about it. The cube now has well over 1,000 shots on it and some of the styrofoam is crumbling off, but it still stops every BB I shoot at it. I consider it an essential part of my shooting equipment; and even though I know it will eventually wear out, I think I’ll get a lot more use before that happens.
I tape a stiff cardboard section to the side of the cube where I plan to shoot. The cube now has holes on all four sides where styrofoam has been blasted out of the center, and I can’t stick any Shoot-N-C target stickers to the center of the cube’s sides. But the cardboard is smooth and takes the stickers perfectly. All I have to do is remove the cardboard after each session, and I think the cube will last a lot longer.
I like using the Shoot-N-C targets with BB guns because of the instant feedback. I’m not going to worry too much about the group size except in relation to my dime, so I don’t care that you can’t really measure a group on a Shoot-N-C target (because the paint flakes off farther in all directions than just the BB hole). The most important aspect is the immediate feedback I get from seeing where the BB went through the target, or after many shots, the fact that there’s no feedback at all. That tells me the BBs are going through the same holes.
This pistol seems to shoot to the exact point of aim at 15 feet, which makes that distance perfect for target shooting. The sights are not adjustable, but they seem to be perfectly centerd and regulated for height in the test gun. However, it does present a problem, as I discovered on the first target.
I use a 6 o’clock hold when target shooting, which means I align the sights with the bottom edge of the bullseye. Many guns are regulated to shoot their BBs up into the center of a small bullseye, but the P-08 places them exactly where you put the sights. So, the group on the first target is low. One shot is in the center, but that was the result of me pulling the trigger to get it to break. In other words, it’s a wild shot.
All the shots but 1 are at the point of aim. Notice how wide this group is. I’m having difficulty controlling the double-action trigger.
Please understand — this is an accurate BB gun. But I’m having difficulty controlling the trigger. That’s a good thing because it means this pistol can help me learn to better control a double-action trigger.
The one thing that the first target demonstrated was that I needed a smaller target. For the second group, I used a repair paster for the first target. That’s just the center of the bullseye and nothing else. I hoped that the group would be smaller with a smaller aim point; instead, it grew in size.
The second group was larger than the first. Clearly, I’m having difficulty controlling the trigger.
Changed the shooting method
If I wasn’t able to shoot well one-handed, then I figured I’d try it from a rested position. I positioned a chair backwards and rested my arm on the backrest, where I shot the third and fourth groups. I won’t show you group 3, but it was about three inches, and I discovered something while shooting it. If you squeeze the trigger too slow, it gets hung up at the end and will never break. Struggling to break the trigger slowly is why this group was so large.
Next, I tried leaning back, so the pistol was rested against the top of the chair’s back. This did improve things, but the trigger was still causing me some problems. As you can see, this group with a rested gun is larger than when I one-handed the pistol.
This group is long and narrow — the result of a trigger that’s releasing at odd times. Only one shot went wide.
Next I decided what I had to do was use two fingers to pull the trigger. And when I did that, it worked! Now, I could control the trigger as I wanted to; and when I did that, the gun shot to the point of aim every time. Only when I struggled with the trigger release did I throw shots out of the bull.
That’s more like it! Six shots in the black and 4 in the white off to the lower right. Two are in the same hole. This is what the P-08 can do.
In reality, you’re probably going to bounce soda cans around the yard and don’t need the pinpoint accuracy this pistol can deliver. It’ll do that all day long. You’re also going to get a workout for your trigger finger, but that will only improve all your other shooting.
This is the first BB pistol in a P-08 wrapper to make it to our shores. As such, it fills a demand that’s decades old. It’s all you could want in a gun for this price. It delivers the power that’s advertised and can nail the target when you do your part. A welcome addition to the marketplace.

The new Umarex P-08 BB pistol is a stunning copy of the firearm.
Time to learn gun terms
Before I start today’s report, I must make a comment. It deals directly with the subject air pistol, but it also deals with many others. The trigger on the Walther P-08 BB pistol is double-action. It is therefore harder to pull than a single-action trigger. I have read several overseas reports of this gun that complain about the “hard trigger pull.” The trigger-pull of this pistol is not hard — it’s double-action, which means that your trigger finger is first cocking either a striker or a hammer before bringing it to the point that the sear releases it to fire the gun.
My own brother-in-law shocked me this past Christmas when I took him to the range and let him fire my Makarov pistol. I told him that it’s a double-action and single-action handgun, so expect the first shot to have a heavier trigger pull. He did and of course the gun’s trigger-pull was heavy. Then, it fired again before he was ready and he remarked, “Wow, this trigger sure gets lighter after the first shot!”
Well, of course it does! It shifts from being double-action to single action, which would be the reason the trigger-pull goes from 10 lbs. down to 3 lbs. On the second and all subsequent shots, you don’t have to pull the hammer back with your finger — the slide does it for you. But it still shocked him.
To me, not understanding this is as absurd as complaining that you can’t find the clutch pedal in a car that has an automatic transmission. But people don’t do that, do they? They “get” that an automatic transmission does away with the need for a clutch pedal.
But new shooters and some that aren’t so new are still not understanding the meaning of a double-action trigger-pull. So, here’s a photo that I’d like you to internalize (if this is something you’re having difficulty understanding).
This is what you are doing every time you pull a double-action trigger — whether you can see it or not.
Back to the test
Okay — rant is over. Today is velocity day, when we test the P-08 pistol with Umarex Precision steel BBs. I noticed when I pierced the CO2 cartridge that the gas leaked more than usual. It caught me by surprise, and I had to tighten the piercing screw several more turns before the face seal finally stopped the gas flow. And, yes, I did have a drop of Crosman Pellgunoil on the tip of the cartridge.
Then, it was a simple matter of loading 21 BBs into the stick magazine, and the gun was ready for testing. You may remember that the advertised velocity of this pistol is 410 f.p.s., so let’s see what it really does.
The first 10 shots averaged 384 f.p.s. They ranged from a low of 378 to a high of 393 f.p.s. The pistol started slow and sped up as the string was shot. I rested a minimum of 10 seconds between all shots.
The second 11 shots (21 in the mag) averaged 394 f.p.s. The low was 391 and the high was 399 f.p.s. The slowest shot in this string was faster than the average of the first 10 shots. The gun seems to be breaking in.
Next, I shot 10 blanks, just to use up some gas because I suspected the next magazine would be all there was. I was wrong about that.
Shots 32 to 42 averaged 382 f.p.s. with a low of 377 and a high of 385 f.p.s. The pistol seems to be settling down.
Shots 43 to 52 averaged 386 f.p.s. The low was 382 and the high was 398 f.p.s. The gun had more shots remaining after this second magazine.
Now, I decided to just shoot the entire 21-shot magazine and record the average. Shots 53 to 74 averaged 381 f.p.s. The low was 358 f.p.s., and it occurred at the start of the string. The high was 388, which occurred at shot 71. Go figure!
The next magazine started at shot 75 and ended at shot 96. The average was 371 f.p.s. At shot 88, the velocity started to fall rapidly. The cartridge was out of liquid and was just putting out residual gas pressure at this point.
How many shots?
I believe this gun will be good for at least 4 full magazines before its time to replace the cartridge. If you don’t replace it then, you could get a BB stuck in the barrel when the pressure drops too low.
I do believe this gun needs to break in a little, and you can expect to see velocities climb a little after several hundred shots have passed through.
I measured the weight of the trigger-pull for you. It’s a light 9 lbs., 2 oz. to 9 lbs., 5 oz. Compared to a Colt or Ruger revolver, that’s very light. There’s a definite stack at the end of the pull; so once you learn this trigger, it should be very easy to control.
Opinions thus far
I still like this pistol. There were no surprises in this test except for the greater number of shots. I’d estimated about 60 good shots and there are really over 84. Watch that piercing screw, as this one seems to need more movement than many CO2 guns on the market. I might have lost another 10 shots just by losing the gas in the beginning.
Can’t wait for the accuracy test!

The new Umarex P-08 BB pistol is a stunning copy of the firearm.
When I first saw this gun at the 2013 SHOT Show, it changed my outlook on the show altogether. Up to that point, I was angry because the show had changed so much. Media Day, the day before the show opens and where members of the media are invited to shoot all the new firearms (and airguns!) at a public range in Boulder City, had tightened up because of past abuses, and it now took an invite from a booth holder to attend. Media credentials, alone, were not enough.
Besides that, the show planners did away with the gold carpet in the two large display halls that I have used for reference and navigation for the past 17 years. Now, the show resembled a bazaar in Mumbai, with crowded aisles and tall structures that limit the view of the surrounding countryside. Suddenly, you’re 5 years old and everything around you is tall, confusing and moving too fast.
Then I saw IT in the Umarex booth. I was being shown the new products by one of their reps and the guy said, “Oh, yeah. They also have a new replica of some vintage gun.” My heart leapt within my chest. Would this be the year that they built IT? Would this be the year of the German Luger?
Sure enough, there it was — displayed for all to see. Only it’s NOT a German Luger — or a Luger of any kind. Because, you see, Stoeger purchased the rights to the Luger name back in the 1920s, so the only pistol that can bear that name legally has to be sold by them.
That’s okay, though, because what we know as the Luger was never called that, anyway — except by us. What the Germans called it was the Pistol ‘08, or P-08. It was standardized (not invented) in 1908 for the German army; and because they were preparing for war at that time, they also nicknamed it the para bellum, which is Latin for “prepare for war.” Hence, the name Parabellum that’s come down to us through history. The firearm is chambered for many different pistol rounds, including a 7.63mm bottlenecked cartridge the Swiss favored and also the .45 ACP for American trials. But by far the most popular chambering is the 9×19mm cartridge that’s also called the 9mm Parabellum (and, yes, the 9mm Luger). Is this all beginning to make some sense?
This iconic German selbstlader (self-loader or autoloader) is as recognizable throughout the world by its very shape as the Broomhandle Mauser and the Colt Single Action Army revolver. It’s the one handgun that, when anyone picks it up for the first time, makes them paraphrase Crocodile Dundee, “Now, THAT’S a gun!”
The P-08 is arguably the most ergonomic handgun ever made. Many companies, like Ruger, copied it for their own guns. And, because it’s chambered for the soft-recoiling 9×19mm cartridge, it’s extremely mild to shoot. Even though the gun is designed for ammunition that’s loaded well above today’s standard 9×19mm loads, its toggle-link bolt and recoiling barrel extension absorb so much recoil that it’s a thoroughly enjoyable handgun to shoot. I know, because I owned one and shot hundreds of hot rounds in it!
But I’m not alone in admiring the P-08. Thousands of shooters around the world feel exactly as I do about the gun. Which is why, when Umarex began making their incredible replica pellet pistols and BB guns years ago, the cry went up to build a P-08. The demand was there from the beginning, but, alas, the dream went unfulfilled. Gun after replica gun came out of Amberg, but no P-08. And people wrote me, asking why. The two handguns I’m asked for more than any others are this one and the Single Action Army.
Well, the wait is over. The Umarex P-08 BB pistol is finally here!
The P-08 BB pistol is all metal on the outside and is pleasingly cold to the touch when you pick it up. A 29.3-oz. unloaded weight gives good heft in the hand without being heavy. The power comes from a standard 12-gram CO2 cartridge stored in the grip. The spring-loaded BB magazine holds 21 Umarex Precision steel BBs. The stick magazine drops free by pressing the contoured round button on the left sight of the grip.
The 21-shot stick magazine drops free of the gun with the push of a button.
I’m testing serial number 12A00004, which tells you it’s an early production gun and you probably have zero chance of buying this one after I’m finished because it’s on loan directly from Umarex. In other words, the production guns aren’t quite here yet. I think this may even be the same gun I saw at the SHOT Show.
The grip panels are black plastic, which is in keeping with later P-08 “Black Widow” firearms. Nothing looks or feels out-of-place. The right grip panel pops off to reveal the CO2 chamber, and the tensioning screw is hidden by the bottom of the magazine that’s molded to appear like the bottom of the firearm mag.
The right grip panel pops off to install the CO2 cartridge. The cap of the magazine covers the piercing screw.
Let’s talk about that molding for a minute. Umarex has been perfecting their casting processes over the years, and they have arrived at the point where I found it difficult to believe that the toggle link did not move when I examined the gun at SHOT. The pieces are so well-defined and appear to be awaiting a pull upwards on the toggle “ears” (the two large round knobs at the top rear of the pistol) that I fiddled with the gun for several minutes — trying to get it to “work.” It fooled me completely.
I heard disparaging remarks from some readers that if the toggle doesn’t work, the gun is worthless, or words to that effect, but do you think we’re asking too much? This is a not a $250 pellet replica pistol. It’s a $60 BB gun — or at least it will be somewhere near that number. It has the weight and balance of the firearm, as well as the ergonomics and wide trigger blade. Isn’t that enough for what they’re asking? Right now, I have to say that it is for me.
The controls that do work are the mag release, as already described, and the safety, which is identical to the one on the firearm. Even the word secured (gesichert) is written in German, as on the prototype firearm it copies.
The safety is in the same place and has the same German word as on the firearm.
The sights on a short-barreled P-08 firearm are fixed, and the rear notch is integral with the rear part of the toggle link. So, when the gun fires, the rear sight moves as the toggle moves. On the firearm, the front sight, which is attached to the barrel, also moves, because the barrel extension does move back when the toggle link breech is opened. But on the BB pistol, neither sight moves because both the barrel and the toggle link are fixed in place.
The trigger is not adjustable and operates in the double-action mode, only. You’ll have to learn how to control a longer, heavier trigger-pull.
Velocity is supposed to be around 410 f.p.s., which is quite brisk for a BB gun. You’ll definitely want a good backstop when you shoot this air pistol, and everyone in the vicinity will have to wear safety glasses for protection from rebounds.
Other than that, this pistol is what it is — a super ergonomic BB pistol (by copying the P-08 profile exactly) with a lot of realism. I hope it shoots accurately because this is definitely an interesting BB gun.
This is the first P-08 BB pistol to hit the market. The realism is remarkable.
When can we expect to see it?
I don’t know just when the P-08 will hit the U.S. market, but I would hope it will be by early summer. I will keep an eye out for it.

Today is accuracy day for the 327 TRR8 BB revolver, and there’s an additional surprise in this report. I was glad to get another chance to shoot this interesting BB revolver that feels so good in my hands. It actually has made me curious about the .357 Magnum firearm. Ain’t that always the way?
I inserted a fresh CO2 cartridge for this session, and we know from the velocity test that there are at least 65 good shots from a cartridge. I’m talking about the best part of the power band, where no excuses for accuracy can be made. So, I could conceivably fire 10 cylinders (60 shots) and be safe. As it turned out, I didn’t even need to shoot that many.
Before the cartridge went in for piercing, it got a couple drops of Crosman Pellgunoil on the small, flat end. That ensures some of the oil will be blown through the firing valve, where trace oil will coat every surface, including all seals and valve seats. I want this gun to hold gas forever, and this is cheap insurance!
I used Daisy zinc-plated BBs, which have proven to be the most accurate steel BBs I’ve found. I was recently surprised to learn that Daisy imports these BBs from China in 55-gallon steel drums, but I do know that they then put every BB through a sorting process here in the U.S. before packaging. Whatever they’re doing is working, because these are the most accurate standard steel BBs I’ve seen. Only the Avanti Precision Ground Shot is more accurate — and you’ll probably only see the difference in a precision target gun like the Avanti Champion 499.
I shot the gun at 5 meters, which is the international distance for BB gun competition. I used a rested two-hand hold with my forearms resting on a sandbag. I don’t believe I can hold the gun any better than I held it for this test.
I had said earlier that I thought I’d be using the bright green fiberoptic sight for this test. This revolver has some of the brightest sights I’ve ever seen. But when I lit the target with the 500-watt lamp, I found that I had to use the conventional sight picture of the front post level with the rear notch and lined up at 6 o’clock on the black bull. The bright light on the target made the fiberoptic tubes of the front post and rear notch go black. It was as if this was a conventional set of sights. The sights were crisper than I originally thought when the target was lit this brightly, so everything worked out quite well.
The first group was shot single-action, which proved to be the most accurate way of shooting this revolver, as expected. I was so close to the target that I saw the first shot rip through the black bull. After that, I fell into a rythym and didn’t check the target again. I shot 12-shot groups, since the cylinder holds six loaded cartridges. When all 12 shots were fired, I checked the target through binoculars and couldn’t believe my eyes! It really appeared as if only 6 shots had been fired, because nine BBs all went into a single tiny hole. I doubt very much that I could repeat such a grouop if I tried 100 more times.
The first group was phenomenal! It appears that 9 of the 12 shots went into the tiny group at the lower right, though the hole just above it may have more than one shot. Entire group measures 0.685 inches between centers.
With the success of the first group under my belt, I thought it prudent to shoot a second group single-action, just in case the first one was a fluke. As it turned out, it was. But I could see this group as it formed, and it looked better than the first one from the firing line. I wasn’t until I examined it in the binoculars that the whole story became obvious.
The larger hole in the center of the bull was visible from the firing line as I shot, but the holes that aren’t in the main group were hidden until I looked through binoculars. This is a more representative 12-shot group and measures 0.858 inches between centers.
I’m satisfied that the 327 TRR8 is an accurate BB gun. I was very relieved that the fiberoptics didn’t have to be used, because look at the precision I got. Combat sights (fiberoptics) aren’t ever going to give you that kind of group.
Next, it was time to try my hand at double-action shooting. This is more difficult, because the longer, heavy trigger-pull causes the gun to move in the hand as the trigger is pulled.
The first 6 shots went so well that I thought I’d be recanting my position on double-action shooting, but the first shot from the second cylinder fired before I was ready and as a result it went wide. It was a called flier that I could see because I was concentrating on the front sight so intently.
The rest of the shots went into a fairly nice group, except that there was one high shot that I cannot account for. But when you’re pulling a double-action trigger and the gun shifts by just a few degrees of angle, it’s enough to throw you off target.
I used the quick-loading procedure that was reported in Part 2 of this report. That’s where you press the mouths of the 6 shells into a layer of BBs, and they all pop into the cartridges. While doing this, I noticed one time that two of the BBs had not popped into their cartridge all the way. That would cause them to have less friction than the other four BBs and that could cause a variation. In handloading firearm ammunition, it would be called neck tension — and it’s a vital component of accuracy.
This is what happened when the cartridges were not pressed down evenly on the layer of BBs. Two BBs are sticking out the top of the cartridges and will have less friction than the other four that are deeper. When they were pushed into the cartridge, a noticeable pop was felt.
The bottom line
This completes the test of the S&W 327 TRR8 BB revolver. We’ve seen how it works and all of its good features. It is a very well-made BB gun that looks like it will give good service for a long time. Accuracy is above average, and the power is well above the modest advertised velocity.
by B.B. Pelletier
The 327 TRR8 BB revolver is distributed by Umarex, which claims the muzzle velocity is 400 f.p.s. In fact, they print it right on the box!
To appreciate what I’m about to tell you, there are two things you must bear in mind. First, the manufacturer of an airgun has to publish the top velocity that gun could achieve. If they don’t, and if there’s ever a lawsuit, it would be bad if the gun was more powerful than advertised. A plaintiff could argue that they bought the gun, thinking it was capable of shooting at a certain velocity, when in fact it was actually capable of higher velocity. They could then argue that they would never have allowed their children to shoot (they may say “play with”) that gun, if they had known its true power.
This argument sounds bogus to a shooter, who would know that any gun is potentially dangerous, regardless of its velocity, but jury selection teams work hard to keep people with such knowledge off the jury, if they can. And to the uninformed, hearing that the gun is more powerful than advertised somehow makes it more evil, if the facts are presented in the right way.
Second, if a manufacturer advertises a certain gun to have a certain velocity and it clearly does not, they have just scored a black eye in marketing and public relations. They are called liars who just want to skew the facts in favor of their product.
This is the dilemma every manufacturer and distributor faces when they advertise their airguns. So what I am going to tell you today must be considered in this light.
Loading the CO2
I showed you the CO2 compartment in Part 1. The cartridge goes in easily, and the piercing screw is turned until a hiss of gas it heard. I then turn the screw just a little farther to make certain the hole in the cartridge is large enough. The pressure of the gas will prevent you from screwing the piercing screw too far.
I should add that, as always, I put a drop of Crosman Pellgunoil on the tip of the cartridge before installing it. The oil gets blown through the gun’s valve and gets onto all the seals. It’s the best thing you can do for your CO2 gun.
The 327 TRR8 BB revolver has both a single-action and a double-action trigger-pull, and each must be tested for velocity. Sometimes, they’re fairly close, but there have been guns where the way the trigger was pulled made a 100 f.p.s. difference.
I used Daisy zinc-plated BBs for all shooting in this test.
Fresh CO2 cartridge — single-action pull
The first 10 shots on a fresh CO2 cartridge averaged 447 f.p.s., which is well about the advertised velocity. The string ranged from a low of 431 to a high of 462 f.p.s. That’s considerably above the advertised velocity and produces an average of 2.26 foot-pounds.
Next, I fired 10 shots double-action and got an average 441 f.p.s. The low was 428 and the high was 445 f.p.s. The average muzzle energy was 2.2 foot-pounds. So, there’s not too much difference between single-action and double-action in this revolver.
The trigger-pull seemed heavier than I remembered from the first report. It averaged 6 lbs., 4 oz. in the single-action mode, which is on the high side. However I must report that the trigger-pull is very crisp. It’s a single-stage trigger in this mode, which means there’s no travel before the trigger stops at the break point.
In the double-action mode, the trigger is easier to pull than on many other revolvers. It breaks at an average 9 lbs., 5 oz. on the test gun. When it’s pulled, there’s a definite stop point where the pull force increases before the release. It feels very much like a Colt double-action trigger from the 1920s rather than a Smith & Wesson trigger — because the Colts always stacked at the end of the pull, while the Smiths did not.
The 327 TRR8 comes with a speedloader, and Paul Capello showed us in his video of the Dan Wesson BB revolver how to quickly load the BBs. The 6 cartridges are loaded into the speedloader, which is then pressed down onto a layer of BBs held in the lid of a pellet tin. All 6 cartridges will be loaded this way, and it works perfectly every time.
As powerful as this revolver is, I was concerned about how many shots a single CO2 cartridge would give. And I wanted to stretch the number to as many as I could get, so I paused a minute between shots. Doing it that way, the first 25 shots were all in the 430+ f.p.s.range, regardless of whether they were fired single- or double-action.
After 46 shots had been fired, the velocity remained in the 412-425 f.p.s. range, again with a minute’s pause between shots. After 62 shots, the velocity was definitely falling and ranged from a high of 397 f.p.s. to a low of 286 f.p.s. at shot 85. In other words, there are plenty of shots in this revolver for the average backyard plinker. The high number of shots surprised me a bit, given the high velocities we saw at the beginning, but I did nurse the gas by pausing so long between shots. If you fire faster, and most shooters will, you can expect at least 10 percent fewer shots and all at a lower velocity. You’ll be able to hear when the velocity trails off and can stop shooting before you jam a BB in the barrel.
Observation thus far
So far, the 327 TRR8 seems to be holding up well. It’s powerful, reliable and gets a good number of shots from a cartridge. The trigger seems good, if not very light. The sights are fiberoptic, but have the brightest green tubes I’ve ever seen, so they’ll be used for the accuracy test, which comes next.
