7.92 mm M.G. 34/41: Dual-Purpose Machine Gun

7.92 mm M.G. 34/41: Dual-Purpose Machine Gun

The German 7.92 mm machine gun, M.G. 34/41, represents one of the later developments of the M.G. 34. These developments occurred in the following order: the M.G. 34; M.G. 34 modified; M.G. 34s; M.G. 34/41. In the course of development, the original pattern of the weapon has been largely retained, but each stage has tended toward simplification and elimination of machined parts.

The M.G. 42 is a new design but has the same tactical employment. It is distinguished by a high cyclic rate of fire and fewer machined parts. The M.G. 42 is described on a separate page.

The M.G. 34 modified is used principally in armored vehicles and differs from the M.G. 34 in that it has a heavier barrel jacket adapted to fit ball-type tank hull mounts, a simplified firing-pin nut lock, and bipod clamps for attaching bipod in emergency use; it has no A.A. sight bracket. It can also be mounted on antiaircraft and heavy ground mounts.

The M.G. 34s and the M.G. 34/41 are identical in appearance, except for the barrel jackets, but are marked as distinct models. They differ from the M.G. 34 as follows: provision for full-automatic fire only; simplified trigger group; shorter barrel with enlarged muzzle end; elimination of firing-pin lock nut; large buffer group; heavier recoil spring; modified feed mechanism. These models can be used on antiaircraft mounts but appear designed for the heavy ground mount.

7.92 mm M.G. 34: Dual-Purpose Machine Gun

7.92 mm M.G. 34: Dual-Purpose Machine Gun

The M.G. 34 is a standard machine gun of the German Army. It cannot be compared directly with any American automatic weapon. It is a multi-purpose weapon and is used as a light machine gun, a heavy machine gun, an antiaircraft machine gun, and also on tanks and other vehicles. Because of its adaptability, it is the most common automatic weapon used by the German Armed Forces.

Without bipod mount, the M.G. 34 weighs 24 1/4 lb., and is occasionally fired by the use of a second soldier’s shoulder as a rest. A light bipod adapts it for prone fire and with tripod mount this becomes a heavy machine gun.

The M.G. 34 is a recoil-operated, gas-assisted weapon, belt-fed, and air-cooled. It operates on the Solothurn rotating bolt-head principle. A simple mechanism makes it easy to exchange a heated barrel for a cool one. It is designed to deliver semi-automatic or full-automatic fire.

Studies at Aberdeen Proving Ground show that it is very easy to disassemble in the field, but cannot be regarded as an easy gun to manufacture on a mass production basis, as compared with the M.G. 42.

Studies of captured guns show that this weapon has a high rate of fire—too high for a light machine gun—resulting in poor accuracy in full-automatic operation. When used as a heavy machine gun it shows excellent stability. It is extremely critical as to adjustment, lubrication, and foreign matter.
