Sig Sauer MPX K Pistol 9mm Luger 4.5″ Barrel with PCP Folding Brace 30 Round Polymer Black

The Sig Sauer MPX redefines submachine guns with a new level in safety and adaptability in the field, as well as reliability that has been proven in even the most harsh environments. The Sig MPX, with its dual-sided magazine release, charging hand, and selector switch is perfect for both left-handed and right-handed shooters. The Sig MPX is operated by a rotating bolt that is fully closed and locked, which offers enhanced safety and reliability. The Sig MPX uses a short-stroke piston to allow it to fire all 9mm ammunition brands and weights without adjusting the gas valve.

The MPX K is the choice of professionals around the world. It features a closed-bolt gas piston system which is extremely reliable and durable. The K, like all MPX models, is modular and can be configured with multiple barrel and handguard lengths. It is also ready for suppressor usage. The Know is equipped with the SIG PCB Folding Brace, which allows it to be folded into a compact size while still being operable. The K features an upgraded M-Lok Handguard that is available in various lengths to cover suppressors. The K has been upgraded with the ultra smooth, ultra fast Timney Trigger. This trigger was designed by Timney in collaboration with SIG. It offers the Timney performance that you’ve come to expect, but it also has the reliability necessary to survive the abuse of a subgun platform. The MPX K is the ultimate modular subgun from SIG.
