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 ...
