History
Adopted by Austria-Hungary in 1907 for their cavalry, the Steyr-Roth M1907 was a landmark first: the first semi-automatic pistol issued as standard equipment to a major army. The unique cartridge was designed so the weapon could not use any other ammunition. The deliberate double-action-only trigger, stripper-clip loading, and non-detachable magazine were all safety features for cavalry use. The M1907 saw service through WWI.
