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 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.
