Happy Independence Day!
Happy Fourth of July to my U.S. readers! And to everyone else, happy Wednesday!
Today, I’ll look at the accuracy of the Colt 1911 Special Combat BB pistol. We discovered in the velocity test that the pistol doesn’t quite reach the velocity advertised. That made it possible for me to start using and testing the new Winchester Airgun Target Cube that serves as a BB/pellet trap. We also learned that the pistol shoots at dramatically different velocities in single- and double-action. Naturally, I looked at both modes in this test.
I shot the pistol at 16 feet (as close as possible to 5 meters — the international BB-gun distance) from a rest. A fresh CO2 cartridge was installed at the start of the test and was used for the entire test.
The first 10 shots were to ascertain how the sights were set. Also, I knew from the velocity test that this pistol needs a couple shots to “wake up” the valve and get up to its top velocity. So, the first 10 shots were just sighters.
I discovered the rear sight needed some elevation. Happily, the sight is completely adjustable, but the direction for a vertical increase isn’t clear. The straight arrow doesn’t tell you which way to turn the screw. Fortunately, the sight works like most other rear sights, and a counterclockwise turn provides elevation. There seemed to be no click detents in the adjustment, so I watched the orientation of the screw slot.
First up were Daisy zinc-plated BBs, and 10 were loaded into the stick magazine. Then, I fired the pistol single-action, using a 6 o’clock hold with the sights. Yes, at just 16 feet from the target, I could hardly miss, but this was a test of the pistol — not of my shooting ability.
Ten Daisy BBs went into a group that measures 1.58 inches between centers. It proved to be the best group of the entire test.
Next, I loaded 10 more Daisy BBs and shot them double-action at a fresh target. As expected the group opened up. This time ten went into a group measuring 2.606-inches between centers. Although, the double-action trigger-pull is relatively light, it stacks at the end and is difficult to control. Nevertheless, this accuracy is minute-of-pop-can at the same 16 feet.
Next, it was time to try the RWS BBs. Though they appear to be even smoother than Daisy BBs, I find the two brands about equal in most guns I have tested. The first ten were fired single action, making a group that measures 2.369-inches between centers. That is nearly as large as the Daisy BBs fired double-action!
Once during the 10 shots, there was a double-feed, and two BBs went down range together. This never happened again, so I don’t think it’s a problem. And, if the wide shot from that double-feed was eliminated, the remaining 9 BBs made a group measuring 1.668 inches between centers — much more in line with what the Daisy BBs did.
The RWS BB single-action group looks large because the hole at the upper right is one of two that went down range together. Take it out, and the group is much closer to the single-action Daisy BB group. Overall group measures 2.369 inches, but 9 shots went into 1.668 inches.
On double-action, I was able to see several of the BBs as they went downrange. They seemed to all be curving to the left — almost as though the gun had a Hop-Up that wasn’t quite adjusted. This reminded me of the gun’s airsoft heritage. Ten shots landed in a 2.128-inch group, besting the single-action group, but only because of the double-feed while shooting single-action. This group also bested the Daisy double-action group
Winchester Airgun Target Cube
I used the Winchester Airgun Target Cube for this accuracy test. It’s a new combination BB/pellet trap that I’ve been eager to include in my testing. The trap is a cube of dense foam that has a metal plate inside. Shoot at it on one side, and you’re just shooting at foam, unless you chance to hit the edge of the metal plate. That’s the side for velocities below 350 f.p.s. Orient the cube the other way and the plate’s in the middle. That’s the side for velocities above 350 f.p.s.
The paper targets were all taped to the front surface of the cube. The solid backing of the cube helped define the BB holes a little. And as light as the cube is, it never moved when hit. The sound when hit is quiet, but it’s noisier than a Quiet Pellet Trap.
Daisy markets this cube and says the side of the cube that’s rated above 350 f.p.s. is good up to 1,200 f.p.s. for .177-caliber pellets. I won’t be testing it at that speed. Several shots in the same place might blow through the metal plate inside the cube, and I’m not a testing laboratory for Daisy or anyone else. I’m interested in how many practical shots we can expect from this trap, so I plan to keep a record. Hopefully the number will be in the thousands, like other commercial BB traps.
The BBs all stayed inside the cube, but it’s too early to say how long this trap will last. As I use it, the tendancy will be to strike near the center of the cube, so in time we will see what effect that has.
What I like about this pistol
I like the trigger in both the single- and double-action modes. I like the adjustable sights, and I like the way the sights look when shooting the gun. I like the snazzy appearance of the gun and the way it is exactly the same size as a 1911 firearm. I like the drop-free magazine/CO2 holder. And I like the velocity that gives a lot of shots per CO2 cartridge. This gun is very quiet and only rates a two on the sound scale!
What I don’t like about this pistol
The accuracy could be better.
The bottom line
This BB pistol has to compete with many other 1911-style BB pistols that all offer a lot for the money. This one probably leads them all in looks, but it trails the field in accuracy. In the end, though, it’s more than accurate enough for a BB pistol.

Wow! Today’s test is as different as any I’ve done! This air pistol surprised me completely, with results I’ve never before seen from any airgun.
The Colt 1911 Special Combat pistol shoots BBs, so a velocity test is going to be pretty humdrum. There are a limited number of different BBs to try, and they aren’t going to give fantastically different results like lead pellets do. So, usually a velocity test with a BB gun is a no-brainer for me. Shoot and record the numbers — plain and simple. But not today.
Both single-action and double-action
This pistol fires in both the single-action and double-action modes. For you newcomers, single-action is where the trigger performs the single functon of releasing the hammer to fire the gun. You have to manually cock the hammer before each shot — the trigger doesn’t do it.
Double-action, in contrast, is where the trigger both cocks the hammer and releases it, all in one smooth pull. So you just keep on pulling the trigger. As long as there’s ammunition, the gun keeps on firing.
Because the trigger is doing more for double-action, it’s always harder to pull in that mode than it is for single-action. So a semiautomatic pistol that has single-action operation will normally have the very best trigger possible. If a gun functions in either single- or double-action like most revolvers, the single-action mode will give the best trigger-pull. The double-action mode is reserved for when you want to fire a lot of rounds very fast.
There’s more to it than that, of course. Some semiautomatic pistols such as the Beretta M92/M9 fire either single- or double-action; but when they fire, the slide comes back and cocks the gun for the next shot. These guns are quick to fire the first shot, since you can carry them with a round chambered and just pull the trigger to get them started. They also have the advantage of switching over to single-action once they begin firing.
At any rate, when I have a CO2 pistol that’s both single- and double-action, I test it for velocity both ways. That often gives results that favor the velocity on one or the other of the two modes. But this gun was vastly different. It varies by about 100 feet per second greater velocity in the single-action mode. And there’s even more to report, so read my results carefully.
I started out shooting the pistol with Daisy zinc-plated BBs in the single-action mode. The gun is rated to shoot at 400 f.p.s., so I expected something in that neighborhood; with BBs, there isn’t much variation between brands. So, I was surprised to see the first shot on a fresh CO2 cartridge register only 205 f.p.s. But sometimes pneumatics and CO2 guns need to “wake up” when they first start shooting after a rest, so I kept on shooting and watching the chronograph. The next shot went 203 f.p.s., but the one after that went 334, then 345, then 366 f.p.s. That last shot was as high as the pistol wanted to go.
My first good string of shots on single-action averaged 363 f.p.s., with a low of 360 and a high of 375 f.p.s. That’s good consistency, after the valve had woken up. I figured shooting the gun on double-action would give similar numbers. Guess again!
On double-action with the same Daisy zinc-plated BBs, the velocity averaged 252 f.p.s. The low was 224 and the high was 280 f.p.s. What a spread, and what a difference from single-action. Next, I shot two more shots single-action to see what had happened, if anything. They went 337 and 321 f.p.s., respectively. The gun was shooting slower, but it was still much faster in the single-action mode.
I then tried the RWS Match BBs that Pyramyd Air doesn’t carry. I’ve found them as accurate and precise as Daisy BBs, and sometimes they give slightly different results. This time in single-action, they averaged 319 f.p.s. with a spread from 280 to 344 f.p.s. In double-action, they averaged 240 f.p.s. with a spread from 227 to 250 f.p.s. And shooting single-action immediately following the double-action string gave me two shots at 324 and 302 f.p.s., respectively.
I was concerned that the pistol seemed to be running out of CO2, so I fired it 20 more shots double-action with no BBs in the magazine, then I fired another shot single-action (with the RWS BBs) that went 321 f.p.s. So, it wasn’t out of gas just yet!
How many shots per cartridge?
At this point in the test there were 63 shots on the cartridge. I fired another 10 blank (no BB) shots double-action and then fired an RWS BB single-action that registered 335 f.p.s. At 84 shots, the gun is still going strong.
I next shot a single Daisy BB on single-action to see if there was still such a difference between the two brands. This one went 327 f.p.s., so both BBs are going about the same speed. The initial string of Daisys was just a little faster for some reason.
I shot another 10 blank shots double-action and then an RWS BB at 327 f.p.s. So, at 96 shots, the CO2 cartridge is still going strong. Then another 10 blank shots, followed by a Daisy BB at 323 f.p.s. That was shot number 107 on the cartridge.
Another 10 blanks shots were fired double-action and then an RWS BB went 331 f.p.s. That was shot 118. Then another 10 blanks, followed by a Daisy BB that failed to register. Then a second Daisy BB went 325 f.p.s. for shot 130. Then another 10 blank shots were followed by shot 141 — an RWS BB at 321 f.p.s.
My gosh — this pistol is starting to remind me of the AirForce Talon SS using the Micro-Meter tank! Another 6 blanks were fired and then the remaining gas spontaneously released from the cartridge. All gas was exhausted, and it was all over. This cartridge had maintained its velocity down to almost the end of the CO2 charge — something I’ve not seen in a long time. For the record, I got a good 140 shots from a single cartridge.
What about the large velocity variation at the beginning of the test? I think we can chalk that up to the gun breaking in. After several hundred shots have been fired, I think the gun will perform more consistently; but I’ll come back in a special test, after we look at accuracy, and rerun the velocity test again.
The double-action trigger-pull broke at an average 10 lbs., 6 oz. of effort. The range went from 9 lbs., 6 oz. to 11 lbs., 5 oz. The faster the trigger was pulled, the lighter it became. The pull effort increases rapidly (stacks) the further back the trigger is pulled.
The single-action pull was a very consistent 3 lbs., 7 oz. The second stage is very apparent (I mean there’s a definite hesitation of the trigger blade at the start of stage two), and there’s just a hint of creep in the second stage.
So far, this ranks as a very interesting BB pistol. The test pistol fell short of the advertised velocity, but delivered a huge number of good shots from a cartridge. I think the way it turned out was better than if the velocity had been higher and the shot count less, because high-velocity in a BB gun is about the worst thing you can have. Given the tendency for BBs to rebound with great speed, you really don’t want them going too fast.
Accuracy testing is next.
