What are we looking for in a blowback action CO2 pistol?

Reality Checks

By Dennis Adler

Blowback action airgun enthusiasts are a relatively new breed in terms of airgun history. Blowback semi-autos have only been around since Umarex and Walther developed the first PPK/S .177 caliber model in 1999. Prior to that Umarex and Walther had developed the non-blowback action CP88 pellet-firing models with a DA/SA trigger, but without blowback action the Walther’s hammer had to be manually cocked each time to fire single action.

This article is more of an open forum for debate than it is about any one specific airgun model. The development of new blowback action air pistol designs over the past several years has almost kept pace with centerfire and rimfire semiautomatic handguns, and in most cases, model for model, leading air gun enthusiasts down a very interesting path, yours truly included.

A little over 17 years ago the groundbreaking Walther CP99 (right) took the CP88 concept one step further with a P99-based polymer frame. The 8-shot, 4.5mm pellet firing, non-blowback action, striker fired air pistol became a training gun for German police using the P99. The concept of learning basic skills and firing without the cost of live ammo (9mm) made the CP99 one of the world’s most popular 12 gr. CO2 pistols. The PPK/S, however, remained the only blowback action CO2 pistol for many years.

When I began writing about air pistols I was already involved with cartridge-firing handguns and, by the nature of my work, reviewing new makes and models for Guns & Ammo, American Rifleman, Combat Handguns, Guns & Weapons for Law Enforcement, Pocket Pistols, and Guns of the Old West, I had access to the very latest firearms.

My history reviewing handguns and rifles for gun magazines and writing gun books goes back to the 1990s, a time when CO2 powered air pistols were, for lack of a better term, in their “primitive” stage of development. At the 2000 Shot Show (the annual international firearms industry tradeshow) I was impressed with the latest airguns from Gamo, Crosman, Beeman, and Umarex, among others, but mostly Umarex, which was showing the very first blowback action CO2 air pistol, a BB gun version of one of my personal favorite centerfire pistols, the Walther PPK/S. This was followed a year later by the Walther CP99, a CO2 powered non-blowback action, pellet-firing version of my other favorite Walther model, the P99. Along with the CP88, introduced back in 1996, Umarex and Walther had set the “adult airgun” market on a new and very intriguing course that not only caught the attention of airgun owners but gun owners as well.

It took years for semi-auto airgun designs to evolve, which was spearheaded by Umarex and their blowback action Colt Model 1911A1 Commander introduced in 2014. With its self-contained CO2 and BB magazine, the 1911 opened the door for even more authentic pistols like the Umarex S&W licensed M&P40 (above) introduced in 2016. This remains the most authentic to the cartridge model of all CO2 blowback action semi-autos and is also used as a training gun.

Today with brand name licensing agreements from manufacturers the world over, the airgun industry is building near 1:1 copies of cartridge-firing handguns. In the past three years alone airgun enthusiasts have had to totally reevaluate their interests and reasons for purchasing a CO2 pistol. This sea change within the airgun hobby spearheaded not only by Umarex but companies like ASG and Gletcher, has transformed BB and pellet-firing air pistols into something far greater than they were even a decade ago. Modern air pistol designs and specifically those I have written about in Airgun Experience in recent months have taken designs further than ever with a handful of models that serve as perfect surrogates for handgun training. As a result, there now exits a crossover between gun owners and airgun owners that once was only a small percentage of the hobby, but now proliferates because hardcore gun enthusiasts (and law enforcement) have realized the benefits of airguns as true training aids. The question I have posed is exactly how much authenticity do airgun enthusiasts expect with the technology at hand?

Models like the M&P40 use actual locked breech designs with a tilting barrel and fully operational slide and locking barrel lug. Not every blowback action airgun uses this elaborate design. The Umarex S&W M&P40 should be the paradigm for all CO2-powered blowback action air pistols.

Plinkers and practitioners

This is almost a question that answers itself in Airgun Experience every time a new CO2 model based on a cartridge-firing counterpart falls short of expectations. This is where the industry, or part of it, and the consumer have failed to fully connect. That connection, however, depends entirely upon everyone’s reasonable understanding of what is practical and what is not. This is where design, manufacturing and marketing either score points or miss the bullseye with consumers. There is a segment of the adult airgun market that wants the most accurate and authentic handling and operating blowback action semi-auto and selective fire pistols and BB/pellet-loading cartridge revolvers possible, and they are willing to pay a premium for them. That is not necessarily the mainstream market. The majority of airgun enthusiasts are plinkers and target shooters, others collect old air rifles, or are into precision air rifle and air pistol competition with PCP models costing far more then even the best hand engraved CO2 Peacemaker. The best competition models cost well over $1,000. These dedicated air rifle and air pistol competitive shooters and serious target shooters are the backbone of the airgun hobby. Those of us who pursue collecting and shooting the best blowback action CO2 pistols and cartridge-loading Single Action and Double Action revolvers are another tier, but it is the plinkers who just want a nice BB gun that looks authentic and shoots well, that make up the greatest share of the marketplace and they spend less than $100 for an air pistol. When a new blowback action model comes close to that price point it is not necessarily going to meet all of the demands of every consumer, especially those who already have a high-quality blowback pistol with every  (or most every) desirable feature.

Close behind the M&P40 is the Umarex Beretta 92A1 introduced last year. This CO2 model emulates in fine detail the current 9mm Beretta 92A1 model. For a full-sized pistol the 92A1 CO2 model is almost in a class of its own. Umarex had this gun nailed down perfectly, including the locked breech barrel and slide design, and then upped the game by adding a selector switch so the air pistol can fire full auto. While this is not a feature of the 9mm 92A1, the selector switch on the airgun is quite unobtrusive and does not interfere with any of the pistol’s other operating features, thus allowing it to be an excellent training gun.

Pyramyd Air has helped to close that gap (and continues to develop new products) with a number of exclusive or limited edition airgun models that provide as much realism as today’s technology can achieve. A few of these guns are remarkable like the selective fire Mini Uzi and the Colt Peacemaker limited hand engraved and custom finished editions.

The king of selective fire pistols is the Mini Uzi submachine gun, which almost perfectly duplicates the 9mm military version and uses self-contained CO2 BB magazines. This is by far one of the most exciting air pistols to shoot and one that every blowback action air pistol enthusiast should have in their collection, along with several extra magazines.

A handful of new (2016-2017) models from major manufacturers like ASG have also followed suit with guns like the latest Dan Wesson Model 715 revolvers, but the mainstream production guns are catering to a broader (less demanding) consumer than many of those who read Airgun Experience. The reality check is looking at what has been developed in the past two years that truly meets the highest expectations.

When it comes to wheelguns, nothing presently surpasses the ASG Dan Wesson licensed Model 715 revolvers for authentic styling and ease of use. The 4.5mm pellet cartridge firing guns are available with 2-inch, 4-inch and 6-inch rifled barrels.

Greater Expectations

Even with all that has been achieved with Western-style airguns since 2015, including the addition of the 7-1/2 inch Colt Peacemaker, the Schofield, and Model 1875 Remington (which should be available shortly), the demand is for more variations of the Peacemaker and Schofield, in line with what the original manufacturers offered in the 19th century. It is understandable, too, that there exists the expectation that what was done nearly 150 years ago out of steel and hand labor should be easy to reproduce today out of alloy with CNC machines and modern casting methods. It should be and is. The proof is in the variety of guns developed and on the market in just the last 18 months. The more tooling that is created, the more variations that are possible and Western airguns will very likely take the lead in groundbreaking technology to offer a greater diversity of models. Ironic in a sense, since contemporary semi-auto designs should be forging ahead of wheelguns when instead they seem to be occasionally stumbling.

The Old West has not been overlooked either and in just two years Umarex has delivered 5-1/2 inch and 7-1/2 inch Colt licensed Peacemakers, Bear River has introduced a full size .177 caliber BB and pellet cartridge loading version of the legendary Schofield topbreak, and Crosman and Remington have teamed up to build a Model 1875 (not pictured). Pyramyd air has also produced its own limited editions of both the Colt and Schofield with period correct hand engraving, bringing the past into the present as no airguns ever have.

Semi-autos are in all truth much more difficult to build, having more moving parts that can break. That’s why revolvers have survived for more than 180 years and the debate of revolvers vs. semi-autos continues to this very day. If you are a wheelgun enthusiast of either Single Action or Double Action models, this has been the best two years in the history of air pistols, and there is no end in sight.

Authenticity is what makes these four exceptional blowback action CO2 models worth owning. Each is almost identical to its centerfire counterpart in handling, trigger design, safety operation, full-size magazine loading and sighting. Though some of the cartridge models actually use tritium night sights, the white dot sights on the airguns are excellent. The only one that actually has a fully adjustable rear sight is the Tanfoglio (third from left) while the others have combat sights identical to the cartridge models for size, shape and sight radius. (Pictured left to right, Umarex S&W M&P40, Umarex Colt Commander, Tanfoglio Limited Custom, and Sig Sauer P226 X-Five)

The greatest ally to forging ahead in airgun design is consumer demand, and those of you who follow Airgun Experience and favor authenticity and accuracy over the expedience of manufacturing for a broader marketplace must make your voices heard. Demand drives manufacturing, but manufacturing also drives the market. That is why we still see new blowback action models with stick magazines and separate CO2 loading channels in the grip frame, even though the demand from the segment of the airgun market driven by gun owners now expects every CO2 blowback action semi-auto to be as good as the Umarex S&W M&P40, Beretta 92A1, Sig Sauer P226 X-Five, Tanfoglio Customs, Umarex and Sig Sauer 1911s, Mauser M712 and Luger P.08. Most of these guns are not high priced (most sell for between $100 and $150), especially for what they deliver in features and accuracy at combat handgun distances. Whether you are using one of these airguns for proficiency training, finding out what you like about the gun for CCW use before stepping up to make the big purchase, have the real cartridge guns and want a matching CO2 model, or are just an avid airgun enthusiast, there is more today than ever before. If you want more, if you want better, and are willing to pay the extra dollars to get it, write a comment, tell a friend to log on and write a comment, make your voices heard. Three years ago barely any of the models pictured in this article even existed. What do you want to see three years from now?

  1. The ultimate pellet shooting CO2 semi-auto pistol would have a full size magazine using pellet loaded cartridges and all other full working features that are on the original firearm. The problem in that scenario is where to put the CO2. Using pellet loaded cartridges leaves no room for the CO2 in the magazine. The other possibility, a more expensive one probably, would be to use individual air pressurized cartridges with the pellet loaded in the tip. There is a company that makes rifles that use individual air pressurized pellet cartridges. I just don’t know if it’s realistically possible to use that design in a semi-auto air pistol, but one can dream.

    One product I would like to see is a second generation S&W 586 CO2 pellet revolver using a full swing out cylinder and pellet loaded cartridges.


    • Agree on the 586 . I just picked up a 686 and it is great. Using a system like the Dan Wesson 715, a second generation 586 as well as a Python should be possible, in pellet version . Still hoping for a Webley MarkVI pellet revolver.


      • A rifled barrel Webley Mark VI pellet revolver would indeed be a fine addition to the series and my collection. In the mean time, I have purchased the Schofield pellet cartridges and intend to try them in the Webley. I already know the cartridges fit the Webley. I just haven’t yet made time to use them to shoot pellets with the Webley to see how well they perform.


        • I have used them in the Webley and the Schofield. They are accurate and hard hitting using alloy pellets . Lead pellets lead the barrel more so you will need frequent cleaning if you use them. Would expect a rifledbarrel version to lose a little of the smooth barrel velocity increase , but retain accuracy out past 30 feet


    • I like the idea for the semi-autos but those individual air pressurized cartridges present the same problem as using current pellet-loading cartridges in an 88 gr. CO2 powered lever action rifle, like a Winchester Model 1873, for example. They would most likely work in the rifle’s magazine but the cases would be ejected after being fired and unless you are shooting in an environment where the ejected cases can be easily picked up, you are going to start losing them outdoors. That could make shooting the air rifle almost as expensive as a real .44-40 Winchester. With a semi-auto pistol if you could have a system that works with a self-contained 9mm-sized, pellet-loaded CO2 cartridge you would have the same problem with losing spent shells after they’re ejected, and the shells would have to exert enough pressure to not only fire the pellet at a decent velocity but drive the slide back to re-cock the mechanism, eject the spent case and chamber another round when it closes. That is likely more than a 9mm-sized pressurized CO2 cartridge could manage. The solution will be a vertical pellet loading, self contained CO2 and pellet magazine like the current BB loading self-contained models. And that combination is yet to be figured out. I am confident, however, that it will be and eventually you will have pellet-firing blowback action CO2 pistols with rifled barrels and correctly-sized, self-contained CO2 pellet magazines.


      • The next advance in pellet guns should be in select fire. I would use a double co2 system and a variation of the Sig320 pistol mag to feed a 30 round Grease gun, M2Carbine, H&K MP5, MAC10, Beretta 96, and hail the King , Thompson


  2. I have learned so much reading these articles, initially my ignorance about the limitations of air(co2)guns lead to unrealistic expectations of what their capabilities are. I couldn’t understand why blowback air guns couldn’t be as accurate or powerful as my 2240 or 1322. As my knowledge base has grown I have come to realize there is no one gun that can encompass every facet of shooting. Each type of gun has its own niche ( is it nich or neesh), which reminds me of an engineering saying, you can make it strong, light or cheap pick two. So when I’m working on my accuracy skills I grab my Crosman 2240, if it’s gun handling, I’m going for my Umarex Colt Commander, and for pest elimination the 1322.



    • That is one version of the Peacemaker that everyone seems to want, that and a Sheriff’s Model with a 2-1/2 inch or 3-inch barrel. My money is on new Peacemaker and Schofield models before we see self-contained CO2 pellet magazines for blowback action semi-autos.


  3. I agree there are two markets in play . The lower end blister pack market , characterized by vague facsimiles of actual handguns. The other the high end box replica airguns represented by the close if not actual clones of actual firearms. The closest to actual firearms are the DanWesson 715 series, the Schofield, Webleyand thePeacemakers. In the semiauto the 1911, the S&W MP 40 and the P08. In semiauto blowback and realism should be the rule. . For those willing to pay a little more ,a classic series would be the way to go . Let’s look at the opening picture of the Ppk and the replica to start . The firearm is a classic and and a relatively expensive pistol . I have an original Ppk/s and an Interarms stainless Ppk . I would like an understudy 22 but they are not readily available and are expensive. I am not talking about the alloy cheapie offered today . The first problem is getting a 12 gm co2 in the grip. The current model has an overly long grip ,different trigger mechanism and the lowest velocity of any blowback pistol replica. One solution would be to offer an exact replica of the pistol with the exact specs. Wait the 12 gm cartridge won’t fit. Right but an 8 gm will so think outside the box . Pocket pistols are largely ignored ,the best are theMakarov Ultra and Beretta 84. What about Bond’s Beretta the 918? How about the Colt 1903/08?. Revolvers are more bb and pellet friendly , it is certainly possible to offer a S&W 1917, classic Model 19, 29. From Colt the Detective Special Diamondback and Official Police as well. Western revolvers have proven popular and there are many possibilities there for sure.


  4. Yeah I’m guessing 500 fps in .22 with a twelve inch barrel. I don’t know if adjustable sights are period correct but they would be nice,with the increased sight radius accuracy should be superb, easpeccially with an accessory stock.


    • The original c.1876 Buntline models used a Flattop-style frame and had a folding leaf rear sight about a third of the way down the topstrap. However, the Peacemaker was also offered with barrel lengths up to 12 inches on the standard SAA frame. Conversely, the Flattop was offered with any barrel length from 4-3/4 inches up to 9 inches, as well as the Buntline with 10, 12 and 16 inch barrels. Flattop models also had taller solid base front sights with a German silver blade. It is possible to make a longer barreled CO2 Peacemaker and maybe even add a Buntline-style skeleton shoulder stock. These are variations to be considered for the future. However, I don’t see a 12 gr. CO2 cartridge pushing a .22 caliber pellet at 500 fps. Right now I’d be happy with a 4.5mm pellet firing Buntline. With the longer barrel we might see alloy pellet velocities of 400 fps or better, which would certainly increase accuracy and range.


      • Yes 500 fps is probably pretty optimistic, I have to quit comparing apples to oranges, my 2240’s efficancy because of the bolt action is not comparable to action pistol innards.


  5. I have a Colt Commander and a Colt Peacemaker both are great guns. The thing is I’m not a confident shooter and by that I mean I’m not sure 100 percent of the time whether it’s me or the gun. So if the sights are poor ( peacemaker) or the platform is weak ( BBs) I’m not sure where the problem is. So I feel a pellet revolver with good adjustable sights ( flattop) would be just the ticket for confident practice and more enjoyable to shoot than the single shot 2240.


    • The most accurate pellet handgun I own is the Colt Peacemaker, nickel 7 1/2 barrel so crude sights do not mean poor accuracy. In bb revolvers my Schofield puts the chrome Python to shame.


      • Yes my Colt peacemaker is comparable to my 2240 in accuracy I just have problems calling my shots with the sights being so hard to define. I thought I was being a little harsh myself on such a fine pistol.


  6. For a great blow back semi auto, I would like Tanfoglio Limited Custom, with a rifled barrel, and using the pellet loading system like the new SA-10 has. What a sweet pistol that would be, if they could refine the long trigger pull that is on the SA-10.
    Best wishes
