The GSG 92 is a very realistic action BB pistol from an airsoft manufacturer.

Today, I’ll test the accuracy of this GSG 92 CO2 BB pistol, and believe me, there has been more interest in this gun in any BB gun I’ve seen in a long time. Not all of the interest is focused on this gun, but I’ll address that later in the report.

As you may recall from the velocity test, this pistol gets about 40 usable shots per 12-gram CO2 cartridge. I kept that in mind as the test progressed, and I never let the gun get too low on power. I also waited for at least 10 seconds between each shot to allow the gun to recover from the cooling effect of the gas. The GSG 92 seems very sensitive to a power loss if you shoot the gun too fast.

The first shots were from only 10 feet to establish where the sights were. Since the sights are fixed and even molded into the slide, there’s no possibility for sight adjustment, so it’s important to know where the gun shoots.

I found the pistol groups lower than the aim point and just slightly to the left. However, with these sights, a 6 o’clock hold on the bull is the most accurate way of sighting, so I simply aimed at a bull above where I expected the shots to land. That worked very well for my shooting, which was done at 15 feet.

I tried to hold the pistol in one hand, but I’m not strong enough to do the gun justice that way, so I sat on the floor and used a two-handed hold with my arms rested on the back of a small chair. I know these groups you are about to see are the very best I can do with this pistol.

I installed a fresh CO2 cartridge and loaded the magazine with Daisy Premium Grade zinc-plated BBs. I know from many past tests that these are among the most accurate BBs in all BB pistols, so I went right to the best. That way, I could concentrate on the other things and not worry about ammunition.

Once the gun was sighted-in at 15 feet, I knew it would shoot about 2 inches low and .25 inches to the left. The shooting could now begin. The first target was shot with a 10-second pause between each shot, to allow time for the gun to recover its temperature. At 15 feet, though, the difference of 30 or even 50 f.p.s. doesn’t really have much of an impact.

The first group seemed to be a good one, and it doesn’t look too bad after all is said and done. But I felt I could do better, so I shot a second group.


The first target caught this satisfying 10-shot group that measures 1.173 inches between the centers of the two shots farthest apart.

After the first group, I settled down and started focusing on the front sight, as you’re supposed to. I noticed that the next group was better, but still about the same amount below the point of aim. This group measures 0.914 inches between centers.


The second target was shot with more focus on the front sight. It measures 0.914 inches between centers for 10 shots.

I checked my past tests of BB pistols, and only the Umarex Makarov beat this one. I think I know why. This GSG 92 has realistic blowback that really bounces the pistol when it fires. I think the movement of the slide might make the difference between this one and the Mak.

The bottom line
For those who were thinking about getting a GSG 92, I would say go ahead. My tests demonstrated a very realistic and accurate performance, and the velocity exceeded factory claims. The one drawback is the low shot count, but for that price you’re getting one very realistic recoiling airgun.

It doesn’t end here
Here’s the rest of the story. While commenting on this gun, a couple readers got into a discussion about the SIG Sauer P226 X5 pistol. The claims for accuracy that were made seemed astounding to me, and since this was the first time in a long time that anyone has championed a BB pistol, I ordered one to test for you. The story continues.

Part 1


The GSG 92 is a very realistic action BB pistol from an airsoft manufacturer.

Today, I’ll report on the velocity of the new GSG 92 CO2 BB pistol. There wasn’t a lot of interest in this pistol, but one reader named Lee was very interested in it. He was comparing several seemingly similar pistols and stated that he was quite interested in the accuracy test. That’s in Part 3, Lee, but I’m also interested. I’ll never forget discovering what an accurate pistol the Umarex Makarov was, and then seeing Crystal Ackley shoot it on camera on the American Airgunner set as the first gun she every shot. We kept backing away from the target but her group never got any larger. Little did I know at the time that she was a natural shooter and would soon be out-shooting Paul Capello and me! Hopefully, this GSG pistol will provide a similar surprise.

How this pistol feeds
I said in the last report that I’d be showing you more of the interesting BB magazine in this report, so I’ll do that first. Because I don’t have video (and PLEASE don’t ask for it in the regular blog!) I’ll have to describe to you what happens when the slide blows back and returns to battery (to the point where it would be locked with the breech if this were– a firearm). In a normal BB gun, nothing happens when the slide returns to battery. The BB remains poised at the top of the magazine, waiting to be blown down the barrel by the blast of gas when the gun fires. Not so with this gun. This gun feeds each BB into the rear of the barrel.


Here the slide is all the way back (to the right) and starting to return to battery. The round projection on the end of the slide will align with the BB in the magazine.


In this photo the slide has returned part way and the round projection has just contacted the BB. It will now begin to push the BB out of the magazine lips and into a ramp that leads up to the rear of the barrel.


Here you see the ramp (the shiny part) the BB goes up to get into the barrel (just visible at the end of the ramp). Once the slide starts pushing it, it follows willingly up this ramp for a positive feed into the barrel.

What is described in the captions of the three photos above is the same feed method used by many semiautomatic pistols to feed cartridges into the breech of the barrel. It is much a more complex feeding process than most BB guns use, but only testing will demonstrate whether it is worth the effort.

Does it work?
The big question I had was if a complex feeding system like this would work reliably. Only testing can show that for sure, so some shooting was in order. And, the answer is that it works, but not every time. The gun was mostly reliable, but there were a couple times when the slide locked back as if the magazine were empty even though there were more BBs ready to go. One function of this pistol is it holds the slide open after the last shot, just like a firearm, but this one was doing it sporadically when there were still BBs in the magazine.

I will watch this trait as the test progresses. It may be that the gun suffers when held with a limp wrist, which is not uncommon with many firearms, as well. It’s possible to make many semiautomatic pistols malfunction by nothing more than holding them with a limp wrist that moves more than expected during recoil.

Velocity
Using Daisy Premium Grade zinc-plated BBs, the gun averaged 332 f.p.s. The range went from a high of 350 f.p.s to a low of 319 f.p.s., and the velocity decline was linear from the first shot to the last. That means the gun is either cooling very rapidly, despite being tested in 75 degrees F temperature, or it’s running out of gas quickly. A second magazine would tell the story.

And tell the story it did. This time I was more positive about the hold and there were zero failures to fire. Then I limp-wristed a couple shots and behold — no more faulty hold-open events. Apparently, that was just a part of the early break-in.

On the second string of shots I allowed at least 10 seconds between each shot so the gun could warm up, and the velocity averaged 336 f.p.s. This time the velocity also descended for the first shot to the last, but the slope was shallower. The high velocity was 345 f.p.s. and the low was 327 f.p.s. Shoot the gun slower if you want more shots per cartridge.

Remember, this is a blowback pistol and some of the gas is being used to power the movement of the slide. That has to detract from the total number of available shots. The third string of ten shots began at 338 f.p.s. and ended at 316 f.p.s. Unlike many other gas guns, this one is getting progressivly slower as it shoots. That’s probably due to the blowback function that needs about the same amount of gas every time it cycles.

I shot a fourth string after waiting 24 hours. I wanted to see if there were ten more good shots remaining on the cartridge. I actually miscounted and loaded 11 BBs. The first shots was 330 f.p.s., so the gun was still on the charge, but by the fourth shot the velocity had dropped off to just 313 f.p.s. That was a clear sign that the liquid CO2 was gone and the gun was starting to drop in gas pressure with every shot. Shot 8 was 265 f.p.s. and shot 11 was 245. The gun is obviously out of gas at this point. That means there are about two full 20-shot magazines per CO2 cartridge. The slide was still cycling on the last shot, but it was going much slower than normal. Any more shots would be risking a jam.

From a realism standpoint, the GSG 92 is about as realistic as they get. The heavy metal slide imparts a good amount of recoil when it blows back, and that’s what a lot of owners will want from this gun. We’ll look at accuracy next. If this pistol is accurate, it’ll be one of the top contenders in the action BB gun class.


GSG 92 CO2 BB pistol: Part 1

Pyramyd Air’s new website is still in the beta stage, and we’re making improvements daily based on customer feedback. If you’ve avoided going to the new site because you hate to see things change or think it’s too different from the old site, here’s part 1 of a 2-part tour of the new site that shows you how much easier it is to navigate, search for products and sort your findings.


The GSG 92 is a very realistic action BB pistol from the airsoft maker GSG.

Today, I’ll start a look at another CO2 BB pistol. This one is from GSG and features blowback. I bet it’ll be a favorite among the BB pistol crowd, both for its great imitation of the Beretta 92 and the fact that it’s all metal. The last Beretta 92FS I tested came from Umarex and remember how wonderfully heavy and robust that one felt. Well, here’s another one, and this time there’s blowback!

The GSG 92 CO2 BB pistol (serial #W01101069200) is a 20-shot repeater with a drop-free magazine that houses the 12-gram CO2 cartridge and has a spring-loaded stick magazine in the front. All the controls on the gun — the magazine release, the slide release and the safety are fully operational; and with the one-piece heavy metal slide that operates exactly like the firearm slide and remains open when the last shot has been fired, a high degree of realism is achieved. Even the disassembly latch operates, and the pistol can be field-stripped, though the steps are not exactly the same as for a Beretta 92 firearm. You do have the luxury of disassembling the pistol, for an added touch of realism. The pistol weighs 42 ozs., which is 8 oz. heavier than an unloaded 9mm Beretta 92 (34 ozs.).


The GSG pistol disassembles this far with ease, though there is no reason to take it apart. It adds realism.

The safety
The ambidextrous safety is what makes this pistol a copy of the Beretta 92 and not the 92FS. The older and rarer 92 (5,000 9mm pistols made 1975-1976) had a safety mounted in the frame of the pistol as this BB pistol does. The 92FS safety is mounted at the rear of the slide.


The safety lever is mounted on the frame and is just a safety on the test pistol. Shown here in the intermediate (fire) position. All the way down is also off safe. Up into the notch cut in the slide is safe. There are no markings for these positions. On other variants of this gun, this switch is also a selector for automatic fire. Being ambidextrous, there’s a similar switch on the other side of the frame.

The safety does not de-cock the pistol like the firearm safety does. It’s just a manual safety and nothing else. The safety on the test pistol is ambidextrous, with levers on both sides of the slide. Unlike the Beretta 92FS pellet pistol made by Umarex, this safety does block the trigger and the hammer. If the gun is cocked and the safety is on, the hammer stays cocked and nothing happens. If the hammer is on half-cock and the safety is on, the trigger cannot fire the pistol, as it’s locked in position. You can see and feel some movement, but the gun won’t fire. The safety cannot be put on when the hammer is all the way down in the fired position. I would not recommend pulling the trigger hard when the safety is on, as it seems to stress the firing mechanism.

One more comment about the safety. When you push it up there are two detents. The lever stops at the first detent which is midway, but that’s not the safe position. When I first encountered this, I uncharacteristically read the manual and was surprised to find “To start shooting, aim at a target, put the selector (1) on the semi or auto position (according to your version).” By “selector,” the manual refers to the safety. Well, the test guns seems to be semiauto, only. The second notch (midway between down and up) did not function differently than the first one (all the way down). Only the uppermost position, where the end of the lever was up in the slide, made the gun safe. So, on the test gun, the “selector” is just a safety.

Manual
Obviously, the manual was adapted from an airsoft manual, because the gun is referred to as a softair in one place. In another place the pistol is called a rifle, so it’s pretty obvious that the manual hasn’t been edited by an English-speaking person. Like all airsoft manuals, this manual is very spartan, so you better be familiar with the general operation of airguns like this, or you’ll have questions the manual doesn’t address.

Sights
Thefront and rear sights are fixed. There’s a strange white marking below the notch on the rear sight that I’ve never seen on any other handgun. It looks like an attempt to make the sights look tactical, but it could also be an exotic Asian version of a tactical sight, I suppose.

Handling
The pistol handles just like a Beretta 92, which means a very wide grip for the double-stack 9mm magazine. Although the double-stack concept isn’t used in the BB gun, it does leave more room for the CO2 cartridge.

The magazine has a contoured floorplate that becomes an extension of the grip. This is a pistol that’s sized for medium to large hands.

The pistol can be fired either single-action or double-action; but because of the blowback feature, all shots after the first one will be single-action. The single-action trigger-pull is light and surprisingly crisp. The double-action pull is also very light and smooth.

Magazine
Like many BB pistols, the magazine incorporates both the BB magazine as well as the CO2 storage. CO2 cartridges are very easy to install, using a large Allen wrench that comes with the gun. Remember to put a drop of Crosman Pellgunoil on the tip of each new cartridge before you pierce it. The oil will be blown into the interior of the valve, where it gets on all the seals and keeps them fresh and doing their job.

The manual refers to a speedloader, but the test pistol didn’t come with one, so I had to load it one BB at a time while holding down the spring-loaded follower. This is tedious until you get the hang of it, then it goes pretty quick. There’s no provision to lock down the follower, so you have to hold it down with your thumbnail.

Barrel movement
The barrel moves to the rear a short distance when the slide recoils. When the slide moves forward, the barrel locks into the slide and the two become an integrated unit. It seems to lock in the forward position well enough, but I guess that’s what the accuracy test will determine.
