Also known as: Mannlicher Model 1901, Steyr-Mannlicher 1901

Overview

The Mannlicher Model 1901 was an elegant, slim self-loading pistol designed by Ferdinand Ritter von Mannlicher and produced by Österreichische Waffenfabriks-Gesellschaft (Steyr). It used a fixed barrel with a reciprocating breech (catalogued as a delayed blowback but functionally a simple blowback) firing the relatively mild 7.63mm Mannlicher cartridge, whose low power allowed an unlocked breech to be used safely. The 8-round magazine was an integral, non-detachable box top-loaded via a stripper clip, and the slide could be held open for safe loading.

Notes

Some references describe the M1901 mechanism as blow-forward, but accessible sources (Forgotten Weapons, GAT Daily) confirm a fixed-barrel blowback; blow-forward applies to the earlier Mannlicher M1894. Lost the 1904-1905 Austro-Hungarian pistol trials. Muzzle energy calculated from bullet mass and velocity.

Background

Internally the M1901 is essentially a single-action revolver lockwork bolted to a blowback slide, hidden beneath the left grip panel. Its 7.63mm round was barely hotter than a .32 ACP, which is exactly why an unlocked breech could safely handle it.
