Sig Sauer MPX Copperhead 9mm 3.5" Black PCB Brace 30+1 PMPX-3B-CH

Sig Sauer MPX Copperhead

The Sig Sauer MPX Copperhead is a compact semi-automatic pistol chambered in 9mm, redefining the submachine gun category with innovative operator safety, adaptability, and proven reliability in harsh environments. Featuring a monolithic Elite Series upper receiver with integrated stock knuckle lower and 3.5-inch barrel with integrated muzzle brake, this pistol includes the patented Pivoting Contour Brace (PCB) for rapid deployment and perfect arm adaptation. The fully-closed and locked rotating bolt with short-stroke gas piston ensures enhanced safety and consistent function across all 9mm ammunition types without adjustments.

Standout attributes include fully ambidextrous controls with dual-sided selector switch, magazine release, charging handle, and bolt release for intuitive operation by any shooter. The gas piston system runs cleaner than direct impingement designs, while the lightweight construction and PCB brace provide stable, comfortable shouldering in a highly maneuverable package. These elements combine cutting-edge engineering with user-focused ergonomics for superior control and reduced recoil in dynamic scenarios.

Ideal for home defense, tactical training, or range use, the MPX Copperhead excels in close-quarters applications requiring quick handling, high capacity, and unwavering reliability. Its modular design, suppressor-ready features, and ambidextrous layout make it an outstanding choice for shooters demanding elite performance in a compact, braced pistol configuration.
