A rimless, straight-taper brass case, Berdan primed. The bullet is steel-jacketed, with an ogival pattern. The round is almost identical to the 9 mm Largo (Bergmann-Bayard), and can only be distinguished by the headstamps and the bullet which weighs approximately 1 g less. However, the Steyr bullet is almost always steel-jacketed, whereas the Largo bullet is the more usual gilding metal. An Austrian service round for many years, this was introduced with the M1912 Steyr automatic pistol and subsequently used in

various sub-machine guns. When the Austrian Army was integrated into the German Wehrmacht. Compatible platforms include 9 mm Steyr M1912 automatic pistol; certain Steyr-Solothurn, Neuhausen and Bergmann sub-machine guns.
