In short: Known as the Steyr-Hahn for its distinctive external hammer, this semi-automatic pistol was engineered for the harsh realities of battlefield service. Beyond its standard military role, the M1912 spawned rare automatic variants and remained in use long after the Austro-Hungarian Empire collapsed, even seeing service with German police forces.

Developed by Österreichische Waffenfabriks-Gesellschaft, the Steyr M1912 was adopted by the Austro-Hungarian Army in 1912. While initially issued to the Austrian Landwehr, it became a primary sidearm during World War I. The pistol is defined by a unique short-recoil system where the barrel rotates 20 degrees to unlock from the slide. This robust design allowed it to maintain functionality under difficult conditions, a critical requirement for military field use.

The M1912 features an integral magazine loaded from above using eight-round stripper clips, a common design choice for the era. During the war, production increased to meet shortages, and the weapon was even exported to Chile and Romania. Following the dissolution of Austria-Hungary, the pistol remained in service with the Austrian Bundesheer and was supplied to Czechoslovakia. In 1938, after Germany annexed Austria, the German Police ordered 60,000 units rechambered for 9mm Parabellum, designating them as the 9mm P12 (ö).

The platform also saw experimental development, including the Anschlagspistole M.12, an automatic version with a fire selector capable of 800 rounds per minute. While accepted into service with an order of 300 units for the Italian Front, its limited magazine capacity made it less than ideal. Later, inaccurate accounts in the 1980s fabricated stories about the weapon, including false claims regarding its role in the assassination of Chancellor Engelbert Dollfuss. Historical records confirm that while a standard M1912 was indeed used in the 1934 assassination, the more sensational tales surrounding the automatic variants remain myths.
