Its most significant upgrade was a take-down lever that eased the field stripping, which was often cited as original M1 design's biggest shortcoming.

[4][5][6] Circa January 2019, Walther introduced the CCP M2 380, a variant with .380 ACP a caliber option.

[7][8][9] 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.

Walther has prepared a list of "test" ammunition and suggested grip instructions for best function, available to owners of the pistol upon request.

Walther has issued a voluntary recall as a result and will be upgrading all affected CCPs in order to remove the risk of a drop-fire.
