The Walther PP (Polizeipistole, or police pistol) series pistols are blow-back operated semi-automatic pistol developed by the German arms manufacturer Walther.
The PPK was released in 1931; it was popular with European police and civilians for being reliable and concealable. During WW2 they were issued to the German military and police, the Schutzsteffel, the Luftwaffe, and Nazi Party officials; it is believed that Adolph Hitler shot and killed himself with his PPK in his underground bunker in Berlin. Moreover, the Walther PPK pistol is famous as fictional secret agent James Bond’s trademark gun in many of the films and novels; Ian Flemming’s choice of the Walther PPK directly influenced its popularity and its notoriety.
The PP and the PPK were among the world’s first successful double action semi-automatic pistols that were widely copied, but still made by Walther.
