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,[2] which headspaces on the mouth of the case. Ammunition was typically packaged in a unique ten-round charger, whose use was (and is) unfamiliar to users of other guns.[2] Austrian military production contained greased un-plated steel-jacketed bullets. A few private firms in Austria manufactured ammunition with cupro-nickel-jacketed bullets.[1]
The Repetierpistole M7 was used by the Austro-Hungarian military through WWI, and saw military and police use in the years following the war, in Italy and several Eastern European countries. The ammunition is said to be "difficult to obtain" as of 2024.[2]
