SIG Sauer MPX Copperhead

SIG Sauer has just announced a new addition to MPX series in the form of the ultra-compact MPX Copperhead. “Sub-compacting” firearms – whether they are pistols, revolvers, SMGs or rifles – seems to be all the rage in the last years, and a world famous manufacturer like SIG doesn’t shy away from this trend: as Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc., explains, “The MPX Copperhead considerably reduces the length, width, and size of the MPX platform making it the most compact addition to the MPX family of firearms.” 

Completely ambidextrous with its dual-sided selector switch, magazine release, charging handle and bolt release, it also features AR-style controls for the happiness of the many shooters, LEO and military operators around the world who are already familiar with the AR platform. Above all, the SIG Sauer MPX embodies the concept of modularity under many points of view, including the quick-change components that allow the user to convert any MPX variant from 9x19mm to .40-Smith & Wesson and even .357-SIG for maximum operational versatility.

Chambered in 9mm Luger, with a total length of 14.5 in / 368 mm and a barrel length of 3.5 in / 89 mm, the new Copperhead version “is the perfect combination of the features and performance our consumers expect from a SIG MPX in a compact package” in Taylor’s word. Weight is 4.5 lb / 2 kg.
