The SIG SAUER MPX Copperhead is the most compact expression of the MPX platform, a 9mm large-format pistol with a 3.5" barrel and distinctive coyote finish. Unlike the blowback designs that dominate this category, the MPX runs a short-stroke gas piston system with a fully closed and locked rotating bolt, producing a notably soft recoil impulse and cleaner operation. The Copperhead's integrated features and pistol-brace-ready rear interface make it a top choice for a truck gun or discreet-carry bag setup. AR-style controls mean instant familiarity for anyone who has run a black rifle.
