The OG-43 and its subsequent version, the OG-44, are Italian submachine guns, designed by Giovanni Oliani of the Società Anonima Revelli Manifattura Armiguerra gun factory in Cremona and intended for the Italian Social Republic. Only a few prototypes of both models were made before the war ended.
The OG-43 was optimized for compactness and ease of mass production. Its receiver is made of stamped sheet metal. The bolt and the recoil spring are housed in a cylinder above the barrel, which reduces muzzle climb when firing. The SMG is a common short-recoil blowback operated weapon and fired from an open bolt in both automatic and semi-automatic modes. Double-stack 10-, 20-, 30- or 40-rounds magazines of the Beretta MAB 38 are used. The OG-44 version is a more traditional SMG, with the common wooden stock and pistol grip.
