"Machine Carbine Promoted" from Tactical and Technical Trends

The following U.S. military report describing the German MP 44 assault rifle is taken from Tactical and Technical Trends, No. 57, April 1945.

Machine Carbine Promoted
M. P. 43 Is Now "Assault Rifle 44"

To bolster troop and civilian morale, the German High Command is now widely advertising the general issue of an automatic small arm which Adolph Hitler has personally designated the "Assault Rifle 44" (Sturmgewehr 44). The much-touted "new" weapon is actually the familiar German machine carbine with a more chest-thumping title.

As reported in the February 1945 TACTICAL AND TECHNICAL TRENDS, recently manufactured M. P. 43's previously had been re-designated M. P. 44, although only slight changes had been made in order to accommodate the standard rifle grenade launcher. M. P. 43's of earlier manufacture incorporating the same changes were merely designated M. P. 43/1. The completely new name of Sturmgewehr (assault rifle) may be intended to erase any recollection of the mediocre quality of the earlier M. P. 43's, at least so far as new troops and the public are concerned. In any event, the introduction of the title Sturmgewehr, together with the accompanying blast of propaganda concerning the weapon, is but another example of German efforts to exploit the propaganda value inherent in weapons with impressive-sounding titles, such as Panzer, Tiger, Panther, and Flak 88. Since the Sturmgewehr is more easily mass-produced than a rifle or machine gun because of its many stampings and low-power ammunition, and because a machine carbine is needed by desperately fighting German infantry in their efforts to stem the assault of American troops, it is natural that the Germans should make every effort to capitalize on its propaganda potentialities. By dubbing the M. P. 43 the Sturmgewehr, Hitler may also succeed in deceiving many Germans into thinking that this weapon is one of the many decisive "secret weapons" which they have been promised, and which they are told will bring final German victory.

History of the Weapon

The true history of this weapon is that, as a result of their combat experiences earlier in the war, the Germans rather tardily decided that they needed a weapon representing a compromise between the submachine gun (or machine pistol) and the rifle. Their requirements called for a gun with the full automatic feature and retaining the handiness and lightweight ammunition of the submachine gun but having greater effective range and accuracy than is possible with a submachine gun firing pistol-type ammunition. It is now believed that the new weapon was developed from an earlier model known as the Maschinen Karabiner (M. Kb. 42) because the general design is similar and the type of ammunition fired is comparable.

The present weapon incorporates a number of progressive changes made with the intention of giving the German infantry a suitable small arm for ranges beyond those of close-quarter fighting. First termed Maschinen Pistole (M. P. 43), it was successively designated M. P. 43/1, M. P. 44, and finally Sturmgewehr 44. Now one of the most common weapons issued to German troops, it is intended in a general way to serve the same purpose as the U.S. carbine, M1. As finally developed, the gun is a fully automatic, air-cooled, gas-operated, magazine-fed, shoulder weapon, firing from a closed bolt and a locked breech. A standard rifle grenade discharger can be fitted to the muzzle in front of the foresight.


In their attempts to produce a light, accurate weapon having considerable fire power by mass production methods, however, the Germans encountered difficulties which have seriously limited the effectiveness of the Sturmgewehr. Because it is largely constructed of cheap stampings, it dents easily and therefore is subject to jamming. Although provision is made for both full automatic and semiautomatic fire, the piece is incapable of sustained firing and official German directives have ordered troops to use it only as a semiautomatic weapon. In emergencies, however, soldiers are permitted full automatic fire in two- to three-round bursts. The possibilities of cannibalization appear to have been overlooked and its general construction is such that it may have been intended to be an expendable weapon and to be thrown aside in combat if the individual finds himself unable to maintain it properly.

The incorporation of the full automatic feature is responsible for a substantial portion of the weight of the weapon, which is 12 pounds with a full magazine. Since this feature is ineffectual for all practical purposes, the additional weight only serves to place the Sturmgewehr at a disadvantage in comparison to the U.S. carbine which is almost 50 percent lighter.

The receiver, frame, gas cylinder, jacket, and front sight hood are all made from steel stampings. Since all pins in the trigger mechanism are riveted in place, it cannot be disassembled; if repair is required, a whole new trigger assembly must be inserted. Only the gas pistol assembly, bolt, hammer, barrel, gas cylinder, nut on the front of the barrel, and the magazine are machined parts. The stock and band grip are constructed of cheap, roughly finished wood and, being fixed, make the piece unhandy compared to the submachine guns with their folding stocks.

The curved magazine, mounted below the receiver, carries 30 rounds of 7.92-mm necked-down ammunition. The rounds are manufactured with steel cases rather than brass; inside the case is a lead sleeve surrounding a steel core. With an indicated muzzle velocity of approximately 2,250 feet per second and a boat-tail bullet, accuracy of the Sturmgewehr is excellent for a weapon of its type. Its effective range is about 400 yards, although the Germans claim in their operating manual that the normal effective range is about 650 yards. The leaf sight is graduated up to 800 meters (872 yards).


Operation of the piece is simple. A loaded magazine is placed into the receiver, the cocking handle drawn back fully, and then released. The weapon is then ready for firing. A safety lever on the left side of the trigger housing should be retained in the safe or up position when the weapon is not being fired. Since it is impossible to determine whether or not a round is in the chamber, the weapon should be considered loaded at all times. A change lever for switching from single shot to automatic fire is located above and to the rear of the safety lever, protruding slightly on either side of the housing. For single shots, the lever protrudes from the left side so that the letter "E" will be visible; for automatic fire, the lever protrudes from the right side so that the letter "D" will be visible.

The following steps are necessary for stripping and cleaning:

1. Press down retainer spring on butt locking pin and pull out pin; at the same time press the butt forward to counteract the force of the return spring.

2. Permit the return spring to extend and then remove the butt.

3. Lift out return spring from butt.

4. Swing grip and trigger group downward about its front retaining pin.

5. Draw cocking handle to the rear and remove pistol and breechblock.

6. Place a punch in a hole provided in the gas block screw, and unscrew gas block following a right-hand thread.

7. Insert a screwdriver under lip in rear of hand guard and remove.

The mechanism is now sufficiently exposed for inspection and cleaning. Further stripping is not possible since all pins and rivets have been preened in production assembly.

All things considered, the Sturmgewehr remains a bulky, unhandy weapon, comparatively heavy and without the balance and reliability of the U.S. M1 carbine. Its design appears to be dictated by production rather than by military considerations. Though far from a satisfactory weapon, it is apparent that Germany's unfavorable military situation makes necessary the mass production of this weapon, rather than of a machine carbine of a more satisfactory pattern.
