The Pistole Parabellum 1908 or Luger Pistol, designated P.04 by the German Navy and P.08 by the German Army, is a toggle-locked recoil-operated semi-automatic pistol. The design was patented by Georg J. Luger in 1898 and produced in 1900. While it wasn't originally chambered in the round, the P.08 was the original platform for which Luger's 9x19mm Parabellum was created, which would become one of the most influential pistol calibers of the 20th century.
The handgun first saw use with the Swiss army in 1900 before it was adopted by the German army as the standard service pistol in 1908, replacing the M1879 Reichsrevolver in that capacity. It principally saw service on the Central Powers side during World War I and to a lesser extent with Nazi Germany during World War II. It was meant to be replaced during the latter conflict by the Walther P38, which had the benefits of being easier to manufacture, maintain, while still possessing a fairly high degree of quality, but the P.08 continued to serve alongside its replacement for the duration of the war.
A version of the P.08, the Lange Pistole 08, was offered to artillerymen as a rudimentary personal defense weapon. It had a lengthened barrel, drum-like coiled extended magazine, and its holster doubled as a stock. A rarer carbine variant has a lengthened barrel and stock similar to the Lange Pistole 08, but also has a wooden handguard under the barrel.
