8mm Roth-Steyr

The 8mm Roth–Steyr is a military centerfire pistol cartridge adopted by the Austro-Hungarian cavalry in 1907 for the Repetierpistole M7—the first self-loading pistol adopted by a major military power. The Repetierpistole M7 was intended primarily as a cavalry sidearm, with a heavier trigger pull that was considered safer for cavalry use. The cartridge was a proprietary 8x18mm round, which headspaces on the mouth of the case.
