text: The Walther PP (Polizeipistole, or 'police pistol') series were introduced in 1929 and are among the world's first successful double action, blowback-operated, semi-automatic pistols developed by the German arms manufacturer Carl Walther GmbH Sportwaffen. They feature exposed hammers, a traditional double-action trigger mechanism, a single-stack 8-round magazine (for .32 ACP version), and a fixed barrel that also acts as the guide rod for the recoil spring. The Walther PP and smaller PPK models were both popular with European police and civilians for being reliable and concealable. They would remain the standard issue police pistol for much of Europe well into the 1970s and 80s. During World War II, they were issued to the German military, including the Luftwaffe.
  The Browning Hi Power is a 13+1-round, single-action, semi-automatic handgun available in 9mm. Introduced in 1935, it is based on a design by American firearms inventor John Browning, and completed by Dieudonné Saive at Fabrique Nationale (FN) of Herstal, Belgium. Browning died in 1926, several years before the design was finalized. The Hi-Power is one of the most widely used military pistols in history, having been used by over 50 countries' armed forces. The name "Hi Power" alludes to the 13-round magazine capacity, almost twice that of contemporary designs such as the Luger or Colt M1911. The Browning was one of the first pistols to use high capacity, detachable magazines.
