The Steyr M1912, or Steyr-Hahn, is a semi-automatic Handgun developed in 1911 by the Austrian firm Steyr Mannlicher for the Austro-Hungarian Army. It was 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.
The M1912 has an integrated magazine situated in the grip, fed by 8-round stripper clips. To reload, the slide is pulled back to expose the action, the clip is inserted along the guides and the rounds pushed into the magazine.
Repetierpistole M1912/P16 is the machine pistol variant which utilizes fixed a 16-round integrated magazine and a Handgun Stock.
