8mm Roth–Steyr
pistol cartridge
The 8mm Roth–Steyr(8×18.6mm) 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. Ammunition was typically packaged in a unique ten-round charger, whose use was (and is) unfamiliar to users of other guns. Austrian military production contained greased un-plated steel-jacketed bullets. A few private firms in Austria manufactured ammunition with cupro-nickel-jacketed bullets.
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.
This brief starts where responsible research should: with the source description of “8mm Roth–Steyr” as pistol cartridge. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as pistol cartridge. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q4645272. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1907 and 2024.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
