SMG 45 Low-poly 3D model

Model + (3 x Textures files: Commando Skin, Jungle Skin, Desert Skin) The SMG 45 is, obviously, chambered in .45 ACP and employs a short-recoil/delayed-blowback-operating system, which allows the barrel to travel rearward approximately 1/3-inch while the bolt stays momentarily locked up. Once chamber pressure drops to a safe opening level, the barrel stops and the bolt continues its cycle of operation. Because the barrel is not fixed, sound suppressors with Nielsen-type recoil boosters should be used with the SMG 45. It ships from the factory with a thread protector in place for unsuppressed use.
