Austrian M1912 Steyr Hahn

Today on Gus’ Gear I have an Austrian M1912 Steyr Hahn was adopted by the Austrian military in 1912. It is chambered for the Steyr 9x23mm cartridge and it has a short recoil system that uses a rotating barrel to lock the action closed until time to open.

The left side view shows the safety lever at the back of the frame that also doubles as a slide hold open catch. This pistol is marked “Steyr 1916” on the slide and has the serial number in the usual place above the trigger. It has a fixed box magazine that is loaded with a stripper clip of eight rounds from the top. When the last round is fired, the empty magazine will hold the slide open and the stripper clip can be inserted, it blocks the slide from closing until it is removed after charging the magazine. The button above the grip is to release the guide at the top of the magazine to remove cartridges. To use it, the slide is drawn back and the safety lever engages the forward catch and the button can be depressed and the magazine will empty itself. The holster is not the standard issue holster for the Steyr Hahn, it is a pattern very similar to the type made for the Rast & Gasser revolvers. This holster is not roomy enough to accommodate the Rast & Gasser revolver and has impressions from having had a Steyr Hahn in it in the past., the regimental marking is BXX for the 20th Landsturm Battalion and the acceptance stamps under the flap indicate it was issued by the Landwehr Monturdepot in 1916

The right side does not have much to show, the end of the take down cross bar is visible at the front of the slide. The cartridges shown are post war manufacture and are loaded eight rounds to a stripper clip with two per box.

Most of the markings under the flap of the holster are illegible, but the rectangle in the lower right have L.W.M.D. Over 1916 indicating it was issued by the Landwehr Monturdepot.

Disassembly of the Steyr Hahn is easy, the cross bar at the front of the slide is removed and then the slide can be moved to the rear and up to release it from the frame. The barrel just sets on the top of the frame. This pistol lacks the main spring retainer and makes it necessary to use a screw driver to depress the main spring for reassembly. This photo shows the angled lugs on the barrel and the cross lug that lock the action until the slide recoils about 1cm and then it will release.
