Walther P5

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 (designated P6 within the West German Federal Police) and Heckler & Koch P7.

Design details

The pistol incorporates many new design features, including a new aluminum alloy frame, trigger mechanism, dual-control mechanism, firing pin safety (US patent number 4313274 dated 1979, authored by Walter Ludwig).

The Walther P5 is a recoil-operated, locked-breech, 9 mm semi-automatic pistol. It utilizes the same design principles as the Walther P38 pistol of World War II fame. The barrel does not tilt following firing in the way that Browning's system does, but rather moves straight back approximately 5 mm (0.20 in). This system results in a very accurate pistol since the barrel is kept parallel with the frame during/after firing. The trigger is a standard double-action/single-action trigger. The slide lock also doubles as the decocker and is found on the left side of the frame. Pressing it once will release the slide, pressing it a second time will drop the hammer without firing the gun.
