It was designed for undercover use and had a shorter barrel, frame and grip. A popular variant, the PPK (Polizei Pistole Kriminalmodell, or Police Pistol Detective Model) was introduced a few months after the PP. Introduced in 1929, the PP became a popular police sidearm in Germany and later were issued to officers in Hitler’s army. Features included a visible hammer, loaded-chamber indicator, hammer-block safety and a combination safety/decocking lever, all still commonly found on many DA/SA semiauto designs. This type of action has set the standard for double-action pistol manufacturers worldwide during the past 90 years. It operates on a straight blowback system and a double/single action with a double-action trigger pull for the first shot and a lighter single-action pull for follow-up shots. The Walther PP (Polizei Pistole) occupies a significant place in firearms history as the first commercially successful double-action semiauto pistol. A number of companies have manufacured PP series pistols.
