The Steyr Hahn M1911 is an alternative designation for the Steyr M1912 pistol — "Hahn" (hammer) distinguishes it from earlier hammerless Steyr designs. The designation was used by the Austro-Hungarian Army to differentiate this external-hammer model from the earlier hammerless Steyr-Pieper designs in service. The M1911 designation refers to the year of military trials, while the M1912 designation refers to the year of official adoption.
