You probably mean the AK-47. But the Ak-47 was not a sub-machine gun, it is an assault rifle. SMG's shoot pistol rounds such as 9x19mm Luger. Assault rifles fire scaled down versions of full power rifle rounds. The AK-47 for example shoots 7.62x39mm which is a scaled down version of the Russian 7.62x54mm rifle round used in the Mosin Nagant rifle.
