The Pistole Parabellum 1908—or Parabellum-Pistole (Pistol Parabellum)—is a toggle-locked recoil-operated semi-automatic pistol. The design was patented by Georg J. Luger in 1898 and produced by German arms manufacturer Deutsche Waffen- und Munitionsfabriken (DWM) starting in 1900 with other manufacturers such as W+F Bern, Krieghoff, Simson, Mauser and Vickers; it was an evolution of the 1893 Hugo Borchardt–designed C-93. The first Parabellum pistol was adopted by the Swiss army in May 1900. In German Army service, it was succeeded and partly replaced by the Walther P38 in caliber 9×19mm Parabellum.
