History
Adopted by Austria-Hungary in 1912 for the Steyr M1912 pistol. The fixed-magazine stripper-clip design was considered safer for military use than detachable magazines. Romanian forces captured large numbers of M1912 pistols in WWII and re-barreled them for 9mm Luger — original 9mm Steyr pistols are marked '08' to indicate the conversion. Original 9mm Steyr ammunition is collector-grade; modern reproduction brass is available.
