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.
