The Steyr M1912 is a semi-automatic pistol, chambered in 9mm Steyr, and developed by Austrian firm Steyr Mannlicher for the Austro-Hungarian army, who adopted it in 1912. During World War I, the weapon was supplied to the professional units of the Austrian Landwehr while older designs were issued to the conscripted Common Army. In the same period, orders for the M1912 were fulfilled for Imperial Germany, in addition to Romania and Chile. Its use continued in World War II, where pistols in 9mm Luger were produced for the Wehrmacht after Austria's annexation.
