The Swiss Cheap Out: SIG 310, aka MP48
The SIG 310 (MP48) represents a simplified, cost-effective evolution of SIG's earlier MK series submachine guns. Despite its compact design and a folding magazine well for transport, it offers surprisingly controllable full-auto fire at a high rate of 1026 RPM. The firearm utilizes a straight blowback, open-bolt system and features a unique retention mechanism for its charging handle.
