At 14.5in (368mm) long, 2.4in (61mm) wide and 8in (203mm) high, weighing 4.5lbs (2kg), the MPX COPPERHEAD features a monolithic Elite Series CERAKOTE finish upper receiver, with an integrated stock knuckle lower, and a 3.5in (89mm) barrel with integrated muzzle brake. 9mm Luger calibre.
It comes equipped with the new SIG Sauer Pivoting Contour Brace (PCB) giving pistol users a brace that easily adapts to the movement of the shooter's arm with a patented swivel operation for perfect placement, and can be rapidly deployed.
Unconventional design, great performance, and brings a high level of operator safety, in-field adaptability and proven reliability in the harshest environments. Completely ambidextrous, the SIG MPX is great for left- or right-handed shooters with its dual-sided selector switch, magazine release, charging handle and bolt release. The SIG MPX operates from a fully-closed and locked rotating bolt, offering enhanced reliability and safety in use. A short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve.
