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.
Gas-delayed blowback should not be confused with gas-operation. In gas-delayed guns the bolt is never locked, and so is pushed rearward by the expanding propellant gases, as in other blowback-based designs. However, propellant gases are vented from the barrel into a cylinder with a piston that delays the opening of the bolt.
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]
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 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]
In 1885, one year after Maxim's first gas-operated patent, a British inventor called Richard Paulson, who a year before had patented a straight blowback-operated rifle and pistol, again, one year after Maxim’s first blowback patent, patented a gas piston-operated rifle and pistol which he claimed could be used with sliding, rotating or ...
