The Steyr M1912 or Steyr-Hahn, is a semi-automatic handgun developed in 1911 by the Austrian firm Steyr Mannlicher. It was developed for the Austro-HungarianArmy and adopted in 1912, becoming the standard Austro-Hungarian military handgun of World War I. The M1912 was originally chambered for the 9×23mm Steyr round. After Germany annexed Austria in 1938, the Wehrmacht ordered 60,000 units rechambered to 9×19mm Parabellum which remained in service until the end of World War II.
