Colt 1911 Special Combat CO2 BB pistol: Part 3
by B.B. Pelletier
Colt’s 1911 Special Combat BB pistol is a knockout for looks!
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.
The 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.
Ten Daisy BBs made this 1.58-inch group at 16 feet.
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.
Ten Daisy BBs fired double-action made this 2.606-inch group. A stacking trigger-pull was the culprit.
RWS BBs
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
Ten RWS BBs went into 2.128 inches shooting double-action.
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 Winchester Airgun Target Cube has its first 50 shots. Ten were from the sight-in.
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.
IZH 53M air pistol: Part 3
by B.B. Pelletier
The IZH 53M air pistol looks like it stepped right out of the 1950s. It’s a modern breakbarrel with a retro look and feel.
Accuracy day for the IZH 53M air pistol, and it’s a day with some good surprises. I want to talk about how this pistol shoots, so I’m going to skip the drama of finding a good pellet, because of the three I tried, only one stood out. That was the one I played with the most.
The sights work fine!
No need to worry about the sights anymore. They shoot to the point of aim and have plenty of adjustment in all directions. They’re also very crisp in the right lighting, which is strong light on the target and the shooter in relative dark.
I did have some adjustment to do in both directions and can attest to the sights adjusting easily and accurately. The windage adjustment lacks any markings on the gun to tell you which way to turn the knob, but it’s clockwise to go to the right and counter-clockwise to adjust left. There are very crisp detents, and the increments of movement are quite small.
The elevation knob is marked but lacks the crisp detents of the windage, so it’s more of a guess. Since I wasn’t going for a score, I stopped when I had the pellets hitting inside the bull at 10 meters.
Trigger
You notice a trigger a lot more when shooting targets than during any other testing; so now that I have more experience with it, I’ll say this one is okay but not great. It feels a little too heavy for the absolutely best work and, being a single-stage trigger, there’s no feeling of control or precision. You just squeeze until the gun fires.
Accuracy
The first pellet I tried was the RWS Hobby that went so fast in the velocity test. Alas, this time they weren’t that good, giving me lots of vertical stringing at 10 meters. That can be caused by a limp wrist or weak grip on the gun, but I’m pretty sure that wasn’t the case this time.
Ten RWS Hobbys made this 3.028-inch vertical string at 10 meters. This is not a good pellet for this pistol.
Next, I tried the Crosman Competition pellets. They grouped better, plus the group was more round and less vertical. That tells me that my grip on the gun isn’t the primary problem. About the time I switched to this pellet, I also started using my real competition shooting glasses instead of my normal prescription glasses. That did two things. First, it sharpened the image of the front sight, because the competition glasses have an adjustable iris to control the amount of light that passes through the lens to the eye. Second, the blinder on the competition glasses meant I no longer had to close my non-sighting eye. That cleared up the image of the sights and target and from that point on sighting was much more precise.
Ten Crosman Competition pellets made this 1.947-inch group at 10 meters. As you can see, it’s rounder than the group of Hobbys shown previously.
Then I tried a group of Gamo Match pellets, but that was a mistake. They shot all over the target, and I was afraid of missing the trap at 10 meters! After shot 7, I stopped and considered what to do next.
Getting better and better
As I shoot, I find that normally I get progressively better as the shots pass. So, the first group will be bigger than the next and so on. But there’s a downside to this. If the gun I’m shooting requires a lot of concentration, I’ll soon become tired and the groups will start to open up. It’s a fine line between getting accustomed to the gun and tiring out.
With the IZH 53M, however, the gun is so easy to shoot and the sights are so easy to see that I don’t tire as quickly. Therefore, instead of selecting another pellet, I went back to the Crosman Competition wadcutters that had already proven good and shot another group with them.
This time, I was definitely in the groove. Each shot felt the same and, what’s more, each shot felt right. When that happens you know you’re shooting to the best of your ability.
This group of Crosman Competition pellets showed the pistol’s capability the best. It measures 1.341 inches for 10 shots.
Summary
Well, that’s it for this one. The more I shot the gun, the more familiar I became with its operation and the better it seemed to shoot — with the right pellets. By the end of the session, I was sorely tempted to bring out my BSF pistol and do a comparison test. But that would not have proven anything, since the BSF is no longer made and the IZH 53M is so inexpensive. Best to just let the results stand as they are.
If I’d continued shooting the pistol, I might have found an even more accurate pellet, for this feels like an air pistol that wants to shoot! It’s an all-day airgun that you’ll enjoy for both plinking and informal target shooting.
The last word
I think the IZH 53M is a great value for the price. You get a lot of performance in this low-cost package, and it’s capable of plinking tin cans all day long.
IZH 53M air pistol: Part 2
by B.B. Pelletier
Announcement: If you missed out on Pyramyd Air’s first shipment of extra Dan Wesson speedloaders with 6 extra cartridges, they’re back in stock.
The IZH 53M air pistol looks like it stepped right out of the 1950s. It’s a modern breakbarrel with a retro look and feel.
Let’s look at the velocity of the IZH 53M air pistol. I wrote about what a nice, calm pistol this is in Part 1, and several readers responded to that. Many of you seem to like airguns that are well-behaved. I also made a comparison between this pistol and the BSF S20 that looks so much like a rifle cut down to fit a pistol grip. If you ever shoot that one, you’ll discover that it’s really a pussycat in lion’s clothing. Though it looks big and mean, it really shoots just as calm as you could hope for — like our test pistol.
Customer issues
Customers give the 53M four stars, and the chief complaints are that it shoots high and there’s no safety. Apparently, the sights have been changed, and we’ll find that out when I test the gun for accuracy. As for the lack of a safety being a problem, I respectfully disagree. I don’t think the pistol needs one. The shooter is the safety for any gun, and no mechanical device adds anything to improve safety.
If you want a safety so you can do things you wouldn’t do with the gun that are not on safe — DON’T DO THOSE THINGS! Don’t even do them with guns that have safeties and are on safe! I’ve had safeties fail so many times that I no longer trust them. If I have a gun that does have a safety, I’ll use it; but in no way will I behave any differently with that gun than I would if it didn’t have a safety. I guess I’ll go down swinging on this issue, but I advise all of you to never trust a safety for anything. Instead, control the gun so it doesn’t need one.
I looked at the advertised velocity and saw that it’s 360 f.p.s. But when I tested my sample pistol, it was much hotter. Someone complained that this pistol has BB-gun velocities, Well, they aren’t Red Ryder velocities! Let’s see what this gun can do.
RWS Hobbys
The first pellet tested was the 7-grain RWS Hobby. This is a wadcutter pellet (a sharp shoulder on the pellet head cuts clean round holes in target paper for ease of scoring) that’s one of the lightest lead pellets available. I would use only lead pellets in this pistol because of the power level. When a gun shoots less than 500 f.p.s., I don’t like to use synthetics or lead-free metal pellets since they don’t perform as well as they do in guns that are more powerful.
Hobbys averaged 409 f.p.s. and went from 391 f.p.s to 420 f.p.s. That’s a spread of 19 f.p.s. At the average velocity, they’re generating 2.6 foot-pounds of energy at the muzzle.
Gamo Match
The next pellet I tested was the 7.7-grain Gamo Match. This is another wadcutter that, though it’s heavier than the Hobby, still went pretty fast. The average was 391 f.p.s. and the velocity range went from 384 to 399 f.p.s. The muzzle energy is an average of 2.61 foot-pounds. The total velocity spread was 15 f.p.s.
Crosman Competition
The final pellet I tried was the 7.4-grain Crosman Competition — yet another wadcutter design. These loaded easier than the first two pellets and gave an average of 389 f.p.s. That works out to a muzzle energy of 2.49 foot-pounds. The velocity in the string ranged from a low of 376 f.p.s. to as high of 394 f.p.s., for an 18 f.p.s. spread.
I tested these pellets because they’re the ones I intend shooting in the accuracy test. I wasn’t looking to show the pistol as a hot-rod, but the results speak for themselves. Also, because this is a springer, there’s always the chance that it will becomes a little faster after a good break-in.
Trigger
The trigger is not adjustable. The Russian-made schematic refers to a “trigger adjustment screw,” but in my gun the screw is only for securing the stock to the action.
Blog readerDerrick gave us a link to a blog he wrote on tuning the gun, and his photos clearly show a trigger travel adjustment screw that’s no longer in the current model. The sheet metal anchor is still there, but no hole has been drilled and tapped for the adjustment screw
The sheet metal anchor for the adjustment screw is still in place, ahead of the trigger blade, but the hole for the adjustment screw is not drilled.
I believe the trigger has been updated, but the schematic still shows the older design. So, I repeat what I said in Part 1 — the trigger is not adjustable. The trigger is single-stage and breaks cleanly at between 1 lb., 15 oz. and 2 lbs., 8 oz. That’s light enough for good informal target shooting.
Thus far
So far, I really like this air pistol. It seems to offer a lot of value for the money. If it proves to be accurate, it’ll be quite a buy!
IZH 53M air pistol: Part 1
by B.B. Pelletier
The IZH 53M air pistol looks like it stepped right out of the 1950s. It’s a modern breakbarrel with a retro look and feel.
I finally got a “round tuit.” I said I would test the .177-caliber IZH 53M air pistol years ago, but something always came up. So, today, we’ll start a look at a gun that turns back the clock on airgun design.
This pistol is a throwback to Diana’s classic model 5 pistol, as well as several other less well-known air pistols of the past. I would say that it resembles the pre-war Diana 5, but some aspects are quite modern. However, from the standpoint of the spindly barrel and calm firing behavior, it’s closer to the pre-war gun than to the post-war pistol that ultimately morphed into a 700 f.p.s. powerhouse.
Quiet!
Is the the 53 calm and quiet? Most assuredly! It reminds me of a Diana 27 rifle that cocks with ease and discharges the same way. The noise level on the website says the pistol is a level 2, but that’s where a five-point numbering scale fails us. Because in my opinion, this is about a 1.2. This gun, combined with the AGE quiet pellet trap, is ideal for those who live in close quarters with thin walls separating them from their neighbors. Believe me, you’ll spend more time keeping the TV turned down than you will worrying about the discharge sound of this airgun.
The gun
The IZH 53M is a breakbarrel spring-piston air pistol. There are no unnecessary safety releases for the barrel — you simply cock it when you’re ready — just like back in 1952! There’s no superfluous automatic safety. The gun is ready to fire when the barrel is closed. All the safety there is has to reside in the hands of the person in control of the gun — as it should! There’s a good anti-beartrap device that prevents the curious from pulling the trigger when the barrel is broken open. If you want to see something flick up fast, buy a switchblade. Don’t play with a breakbarrel airgun that way!
This is what loading a breakbarrel air pistol looks like.
The grip is really a stock in which the entire action resides. In this respect, the gun is more like a BSF S20 pistol. The grip/frame is ambidextrous and made of a rough, black synthetic that grips your hand aggressively. The metal parts are not polished but appear to have been blacked just as they came from the tumbler, which gives them a rough satin finish.
Sights
Although the pistol has the look and feel of the 1950s, you can see the refinement that’s taken place over the years. For one thing, the grip has been changed to better fit all hands. And the sights! Well, what can I say except that they remind me of the good old days when the IZH 60 was made with a steel receiver! The rear sight is such a masterpiece of design ingenuity that I’m showing you a closeup picture. The windage adjustment has sharp, crisp detents to let you know exactly what’s been done. The elevation screw is quiet (has no clicks) and without detents, but it is positioned perfectly and works exactly the way you think it does. This sight, which is made of a combination of synthetic and metal parts, puts me in mind of the rear sight on a BSF S20 Target model that’s so finely crafted.
The rear sight isn’t just adjustable in both directions. It’s also designed to fit the gun and look nice. This is one you’ll be proud to own.
The front sight is a sharp post on a ramp; and because it’s so simple, it’s the perfect place to use synthetic material. It’s clever thinking like this that bespeaks the high level of engineering that must have gone into the gun.
Barrel
That leads me to wonder if the Russians have continued their quality quest over to the barrel. We know from examples of the past that the Russians know how to rifle airgun barrels. And the several times I loaded a Crosman Premier lite pellet to shoot the gun, I noticed that it fit the breech just like it would fit an FWB 124 breech. So, I’m hoping that the barrel on this pistol is everything the Russians are capable of making. At just $65, I don’t see how it could be. How can they turn out a gun that retails for so little yet has all these quality features and is accurate to boot?
Power
Here’s where the truth comes out. The gun cocks easily and is quite smooth when it fires. Therefore, it isn’t a magnum pistol. The advertised velocity is 360 f.p.s., but I’ll test it with real-world pellets so you know what to expect when you get it. But the point I am making is that, just like the Diana 27, that isn’t very powerful, neither is this pellet pistol. It’s just fun to shoot.
I’ve found over the years that the gentle airguns are the ones that live on in people’s memories and become classics. I’m talking about guns like the aforementioned Diana 27, the FWB 124, the Air Venturi Bronco – and perhaps this pellet pistol.
Trigger
The trigger isn’t adjustable, but it’s very nice just the same. It has a single-stage pull that I’ll tell you more about in Part 2. It’s very crisp for what it is and worthy of being on a gun costing twice as much.
Cocking and firing behavior
And that brings me to the cocking and firing behavior. Again, I’ll say more about this in the next report, but for now you should know that the gun fires smoothly and has little vibration. When you cock it, the mainspring sounds just like a vintage gun from the 1950s. It’s all scrunchy and spring-sounding, and it’s during this endeavor that you learn of the extra safety that’s built into the gun. There’s a ratcheting device that grabs the spring incrementally as it’s compressed; so if you were to let go of the barrel, it would not snap back. That’s where the 1950s are left behind and the Third Millenium design takes over. This device is quiet and unassuming — and unless you test for it by letting off on the barrel while cocking, you’ll never even know it’s there.
There isn’t a lot of time left before Christmas. If this model is of any interest, you’ll have to take a chance that it fits your needs. All I can say at this point is that I’m impressed!
Something for you: A homemade pellet trap
by B.B. Pelletier
Plans and photos by Jim Contos
We all need something to shoot at, and I don’t mean targets. BB guns and pellet guns are great to shoot around the house as long as you’re stopping and capturing those projectiles safely. When I began shooting pellet guns in my apartment in Germany in the 1970s, I mounted a metal pellet trap similar to the Gamo cone pellet trap to the inside of a steel-sheathed front door. In two years of shooting thousands of shots at that small trap, I never missed it once, though today I would advocate a larger trap for a greater margin of safety. The steel sheathing on the door was my backup plan, but in retrospect, that was a bit risky.
I shot only lead pellets at that trap, which is important to know, because it’s not suited for steel BBs. Lead pellets deform and give up most of their energy when they hit a solid surface, while steel BBs rebound at nearly the same velocity at which they came in. A suitable trap for BBs would to slow them to a gradual stop without the risk of a rebound. While there are traps that are well-suited for BBs, perhaps the best trap is the one that works well for both BBs and pellets, and that’s the trap that’s packed with duct seal, like Air Venturi’s AGE Quiet Pellet Trap. Everything that hits the duct seal is caught and prevented from rebounding.
The cost of a quiet or silent pellet trap comes from two things. First, the duct seal in the trap is somewhat costly on its own, and second, of course, the labor to build the trap adds to that cost considerably. Before the commercial duct seal traps were available, I made my own silent pellet trap about 15 years ago. So far, it has stopped untold thousands of BBs, pellets and even the occasional .22 rimfire bullet.
Another feature of these traps is that after they get full of thousands of lead pellets they become extremely hard to penetrate and are then suitable to stop bullets with up to about 45 foot-pounds of energy. When new, the same traps are best held to no more than 30 foot-pounds if they have a metal backing and 15 foot-pounds if not. I’ve already destroyed a fine custom-made wooden trap because I shot too many 30 foot-pound shots to the same point of impact and blew through the wooden back of the trap.
Today, I’ll show you a pellet trap that you can make quickly at low cost from a PVC fixture and metal electrical junction box covers you buy at the local hardware store. Blog reader Jim Contos gave it to me a few weeks ago, along with the plans and the photographs you are about to see, at the 2011 Malvern [Arkansas] Airgun Extravaganza. Those of you who subscribed to my newsletter, The Airgun Letter, may remember Jim as the man who guided me through the trigger modification on my Beeman P1 in 1996.
Better than it sounds
This trap is more substantial than it sounds. When Jim described it to me at the show, I didn’t think much of it. But when he put one into my hands a few minutes later, everything suddenly cleared up. Although it’s made from a plastic PVC cap, it’s the eternal grade of PVC — the Schedule 40 stuff that takes a log time to degrade and can take all the smallbore airgun punishment you can dish out. When I tell you what Jim did to test one, I believe you’ll come to the same conclusion.
Materials
To make a trap like this you’ll need the following:
One 7-inch Schedule 40 White Cap PVC Socket Fitting (it’s really a little larger than 7 inches across)
Two 4-inch steel electrical junction box covers
Enough duct seal to suit yourself (around 6-8 lbs.)
Making the trap
Step 1. Roll a quarter-stick of duct seal into a ball and place it in the center of the cap.
The first ball of duct seal goes into the cap.
Step 2. Press one of the two electrical junction box covers down on the duct seal, squashing it.
The first metal plate has been squashed down on the ball of duct seal.
Step 3. Place another ball of duct seal on top of the junction box cover.
Step 4. Place the second junction box cover on top of the new ball of duct seal and turn the cover 45 degrees from the one below so the two covers are offset the maximum amount.
A second ball of duct seal was placed on the first metal plate and squashed by the second plate. Notice the plates are offset as much as possible to cover the back of the trap better.
Step 5. Fill the cap with the rest of the duct seal, making a relatively smooth surface on top.
You’re finished. Attach a paper target directly to the duct seal in the trap with a push pin or other thumbtack-like object, and you’re ready to shoot.
It’s this easy to fix a target to the trap. Smudges on target are caused by the oil exuding from the duct seal. This target has been mounted for several weeks.
The cost of this trap will vary, depending on the cost of the materials. There have been numerous discussions on this blog about where to buy duct seal at the lowest price, and I’m quite sure this report will generate a new list for anyone who missed out on the others. I bought 18 lbs. of the stuff a couple years back and used half of it to refill my old homemade trap. It’s already in need of another refreshing.
I never bother cleaning my traps because it isn’t uncommon for me to shoot 500 to 1,000 pellets a week at it. Sometimes, when I’m testing BB submachine guns, I shoot that much in a few hours. I would constantly be cleaning the thing. Instead, I cover the face with cardboard and always place the trap inside a cardboard box that has low walls, to catch any pellets or BBs that happen to bounce out. After 10,000 pellets have impacted, there’s a wall of solid lead that’s far stronger than straight duct seal, but the downside is it crumbles more and can be a bit dirty. The box the trap sits in takes care of that.
Testing the homemade pellet trap
Jim said his trap could take 30 foot-pound hits all day long from the start. Those metal plates in the center will stop a lot, as we will shortly see. When he went home, he decided to test an older trap with a real acid test, just to be sure. He covered the older duct seal in the trap with a fresh coat of fresh duct seal and proceeded to shoot at it from six inches with a .45 caliber Sam Yang Big Bore 909! That’s a big bore air rifle that generates around 200 foot-pounds at the muzzle. Kids, don’t try this at home!
He pressurized the reservoir up to 3,000 psi, set the power on high and let fly with a 170-grain round nose bullet. The bullet penetrated three inches into the trap, hit the top steel plate and rebounded 1-1/2 inches.
A .45 caliber, 170-grain round nose bullet fired from a Sam Yang 909 penetrated three inches into the trap, then rebounded 1-1/2 inches off the top metal plate. The trap was unharmed.
Bullet on the left was removed from the trap after firing.
Jim told me he thought the trap might cost $15 to build. Even if it’s twice that much, it’s still a great savings. The whole project won’t take more than an hour from start to cleanup, and you’ll have a pellet trap you can use for decades to come. When the duct seal gets too loaded with pellets, just dig it out of the trap and replace it with fresh material. The metal plates you continue to use.
Now there are other ways to do the same thing. For example, you can just buy a larger metal junction box, pack it with duct seal and, presto, you’re done. But those larger boxes do cost more money, plus they hold more duct seal. This idea is one of the more economical ones that still offers great protection.
