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