About the Walther PPK?

The Walther PP (Polizei Pistole) was introduced in Germany in 1929 as a sidearm for the German police. The smaller PPK was banned for importation into the U.S. by the Gun Control Act of 1968. An even shorter model (the PPK [Kurz]) was introduced later to make the gun more concealable. Originally, the PP and PPK were .32 ACP (7.65mm) caliber, but the cartridge was later increased to the .380 ACP (9mm Kurz). The PPK/S is chosen by many organizations, including the British secret security, as a powerful and reliable sidearm.
