In Grand Theft Auto: San Andreas and Grand Theft Auto IV, the Micro SMG is actually a civilian-legal pistol version of the IMI Micro-Uzi sub-machine gun but called Micro SMG in-game, while it is a full-sized IMI Uzi submachine gun in the other games. It can be identified as the pistol version because the side-folding wire stock is deleted, and there is no provision on the rear of the receiver to mount one. One can only assume that the pistol was illegally modified for full-automatic operation.
