The Roth–Steyr M1907, or, more accurately Roth-Krnka M.7 was a semi-automatic pistol issued to the Austro-Hungarian Kaiserliche und Koenigliche Armee cavalry during World War I. It was the first adoption of semi-automatic service pistol by the land army of a major power.
The Roth–Steyr pistol fires from an unusual style of locked breech. The bolt is very long. Its rear end is solid, except for a sleeve for the striker, but its front part is hollow and fits tightly over the barrel. The interior of the bolt has cam grooves cut into it, and the barrel has studs which fit into the grooves. When the pistol is fired, the barrel and bolt recoil together within the hollow receiver for about 0.5 inch. During this operation, the helical grooves in the muzzle bush cause the barrel to turn 90 degrees clockwise, after which it is held while the unlocked bolt continues to the rear, cocking the action as it does so. For safety with intended use by mounted cavalry, the pistol has a heavy trigger pull against the firing striker spring, similar to a hammerless revolver.
The Roth–Steyr is a locked-breech pistol, which allows the barrel and bolt to recoil together within a hollow receiver. It is chambered for a cartridge specific to this model. The Roth–Steyr does not have a detachable magazine, but features a fixed magazine loaded from the top with stripper clips. The sights are fixed, the grips are wooden and terminate in a lanyard ring. Rifling is four grooves with right-hand twist.
Production and distribution
The pistol was developed by the Czech designer Karel Krnka, working for an ammunition company of Georg Roth, from an earlier design of Roth–Theodorovic pistol. After development and tests of several prototypes, the final version of the Roth–Krnka won a contest for an Army pistol in 1906, and was adapted as a standard gun of Austro-Hungarian Army as: Repetierpistole M.7. (self-loading pistol M1907). Since Roth had no weapon production capabilities, the government bought all the rights and ordered production in the Österreichische Waffenfabriksgesellschaft (OEWG) in Steyr and FEG in Budapest. From 1908 to 1914, approximately 99,000 weapons were manufactured (the Army received 59,334 from Steyr and 38,213 from FEG, plus several hundred were sold on the civilian market). Despite common name for the pistol Roth–Steyr, Steyr works did not participate in its design, apart from minor improvements. Following the dissolution of Austria-Hungary, the Roth–Steyr was fielded by Yugoslavia, with limited use during World War II by the Austrians and Hungarians. Italy received a number of pistols as World War I reparations from Austria-Hungary, and these pistols were used by Italian troops during World War II. They were used also in Czechoslovakia and Poland.
