Walther CCP

The CCP’s SOFTCOIL™ gas-delayed blowback system uses 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 is accomplished by means of a piston contained inside of a cylinder located under the barrel that opposes the rearward motion of the slide until the gas pressure has declined after the bullet has left the barrel. This allows the slide to end its rearward motion, opening the breech, and ejecting the empty cartridge case.
