The Gewehr 41 rifle, commonly known as the G41(W) or G41(M), is a semi-automatic rifle manufactured and used by Nazi Germany during World War II.

By 1940, it became apparent that some form of a semi-automatic rifle with a higher rate of fire than existing bolt-action rifle models was necessary to improve the infantry's combat efficiency. The Army issued a specification to various manufacturers, and Mauser and Walther submitted prototypes that were very similar. However, some restrictions were placed upon the design:

Both models therefore used a mechanism known as the "Bang" system (after its Danish designer Søren H. Bang). In this system, propellant gases were captured by a cone-shaped gas trap at the muzzle, which in turn deflected them to operate a small piston which in turn pushed on a long piston rod that opened the breech and re-loaded the gun. This is as opposed to the more common type of gas-actuated system, in which gases are tapped off from the barrel, and push back on a piston to open the breech to the rear. Both also included fixed 10-round magazines that were loaded using two of the stripper clips from the Karabiner 98k, utilizing the same German-standard 7.92×57mm Mauser rounds. This in turn made reloading relatively slow (as compared to rifles which had magazines that could be reloaded from a single unit, such as the M1 Garand, although it was typical for its time, being identical to the reloading procedure of the 10-round Lee–Enfield).

The Mauser design, the G41(M), was the only one of the two that respected the criteria imposed. The end result was an overly complex, unreliable, clunky and heavy rifle. It incorporated a familiar sighting and control arrangement to the standard Kar98k rifle. The G41(M) was striker-fired, rotating-bolt locking and featured a traditional bolt handle/charging handle that automatically disconnected the bolt assembly from the recoil spring should the rifle be used in manual mode. The flag-type safety cams and blocks the striker. Only 6,673 were produced before production was halted, and of these, 1,673 were returned as unusable. Accuracy issues were noted since the front sight was mounted on the gas tube in front of the barrel, producing play after sustained fire. Most metal parts on this rifle were machined steel and some rifles, especially later examples, utilized the Bakelite type plastic hand guards.
