The Roth–Steyr M1907, or, more accurately Roth-Krnka M.7[2] was a semi-automatic pistol issued to the Austro-Hungarian kaiserliche und königliche Armee cavalry during World War I.

Its rear end is solid, except for a sleeve for the striker, but its front part is hollow and fits tightly over the barrel.

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 in the intended use by mounted cavalry, the pistol has a heavy trigger pull against the firing striker spring, similar to a hammerless revolver.

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).

The trials are exhaustively described in the Minutes of the Small Arms Committee, starting in April 1900 with the Borchardt and ending with the adoption of the .455SL Webley in 1912.

In March 1903, another Roth pistol was tested (Minute 745), this time in “.0.44 in (11 mm) caliber” with a bullet of 247 gr (16.0 g) which gave a velocity of 975 ft/s (297 m/s).

The conclusion was that the method of loading was unsatisfactory, pull-off too heavy, too many openings to admit dust but Figure of Merit was good.
