The Mannlicher M1901 was a semi-automatic, delayed blow-back pistol made by Österreichische Waffenfabriks-Gesellschaft (later known as Stey-Mannlicher) , Steyr, Austria. 4,000 of them were made betwen 1901 and 1905. Mannlicher M1901 was not adopted by the Austro-Hungarian army but many officers were purchasing them privately. The M1901 is a delayed blowback. On firing, the slide runs back against the pressure of the recoil spring until the lever in the slot on the right side is forced downward. This is resisted by the pressure of the mainspring so that resistance additional to that of the return spring has to be overcome. The slide cocks the hammer as it runs back, movement of the hammer, by way of the mainspring, places even more pressure on the retarding lever. This adds friction to the slide, retarding its motion and absorbing some of the recoil energy. The slide returns alter reaching the end of its stroke and chambers a fresh round from the magazine. The magazine, integral in the butt, is loaded from a charger through the open action. A catch can usually be pressed to expel the contents of the magazine upward through the open action.
