The Walther CCP is operated by a gas-delayed blowback system, using gas pressure from the ignited cartridge by directing it through a small port in the barrel in front of the chamber to slow down and delay the rearward motion of the slide. This design is nearly identical to the design of the Heckler & Koch P7. Walther calls this system Softcoil.
This system had its origins in the late-war StG 45(M) assault rifle prototype. Roller-delayed blowback was first used in Mauser's Gerät 06H prototype. Roller-delayed blowback operation differs from roller-locked recoil operation as seen in the MG 42 and gas operated roller locked, as seen in the Gerät 03 and Gerät 06. [25]
A schematic of the P7's gas-delayed blowback system.. The P7 is a semi-automatic blowback-operated firearm. It features a unique gas-delayed blowback system modeled on the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol [6] (and ultimately on the Barnitzke system first used in the Volkssturmgewehr 1-5), [7] which used gas pressures from the ignited cartridge and fed them through a ...
The Steyr GB is a semi-automatic, blowback-operated firearm. It features a unique gas-delayed blowback system based on the Barnitzke system, first used in the Volkssturmgewehr 1-5, [5] and subsequently in the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol. [6]
The pistol originally sold in the United States for a retail price of approximately $400. In Italy the pistol was chambered for the 9×21mm IMI cartridge. [3] The CP1 uses a gas-delayed blowback action with a gas cylinder located below the barrel. The trigger is a single action, internal hammer. [4]
Roller-delayed blowback: Muzzle velocity: 868 m/s (2,848 ft/s) (Bullet velocities are highly variable as this metric is dependent on bullet weight and both the powder used and the weight of the powder charge. The velocity shown above is only a representative sample measurement.) Effective firing range: 1,000 m (1,094 yd) Maximum firing range
The HK P9 is a semi-automatic pistol from Heckler & Koch in 9×19mm Parabellum, .45 ACP, and 7.65×21mm Parabellum and the first to use a variation of H&K's roller delayed blowback system in a pistol format and polygonal rifling [1] now common in H&K designs.
