The Sig Sauer MCX Off-Duty pistol in .300 Blackout with a 6.75-inch black barrel (brand part no. WPMCX-300B-6B-LT) shortens the MCX platform for maximum maneuverability, part of Sig Sauer’s Off-Duty program offering exclusive pricing to American professionals who protect, serve, and defend their communities. Sig Sauer feeds the pistol from a 30-round magazine, and the shorter 6.75-inch barrel favors close-quarters maneuverability over the longer 9-inch configuration. Among compact AR-pattern semi-auto handguns, this MCX Off-Duty configuration favors shooters who prioritize a shorter overall length.
