The Walther P5 is a 9mm semi-automatic pistol developed in the mid-1970s by the German small arms manufacturer Carl Walther GmbH Sportwaffen. It was designed with the German police forces in mind, who sought to replace existing 7.65mm pistols with a modern service sidearm incorporating enhanced safety features and chambered in 9×19mm Parabellum. A subsequent bid resulted in the Walther P5 being introduced into service alongside the SIG Sauer P225 and Heckler & Koch P7.
