This MPX-P uses SIG’s short-stroke gas-piston system with a closed, rotating bolt, designed to keep the action running clean and smooth. The 8-inch barrel is threaded and fitted with a slotted flash hider from the factory, giving the muzzle a finished, ready-to-use configuration.
The aluminum handguard is free-floating and slotted, with an integral front handstop for added control. A full-length MIL-STD-1913 top rail spans the receiver and handguard, and a rear 1913 rail supports the right-side folding arm brace with a hook-and-loop cuff.
Controls are ambidextrous, including the manual safety and dual-latch charging handle, with a left-side bolt catch observed. The textured polymer pistol grip provides a secure hold, and the pistol ships without sights, matching the factory configuration.
Capacity is 35+1 with the included SIG Sauer MPX 35-round translucent polymer magazine. Receiver markings include "SIG MPX," "SIG MPX MULTI-CAL.," and "SIG SAUER INC NEWINGTON NH USA," reflecting its U.S. manufacture.
