A stainless Walther PPK.
The Walther PP (Polizeipistole, or Police Pistol) series pistols are blowback-operated semi-automatic pistols, developed by the German arms manufacturer Walther.
It features an exposed hammer, a traditional double-action trigger mechanism,[3] a single-column magazine, and a fixed barrel that also acts as the guide rod for the recoil spring. The series includes the Walther PP, PPK, PPK/S, and PPK/E.
A smaller, Walther PPK pistol appears as Jack Travis main sidearm for the first half of Lethal Weapon 3 before switching to a Smith & Wesson Model 29.
