The Mossberg 940 Pro Tactical SPX is a 12 gauge gas-operated semi-automatic shotgun (Mossberg part no. 85188) built for shooters who need a tactical autoloader that keeps running. Mossberg took the already-proven 940 Pro Tactical platform and layered in an optic-ready receiver, a redesigned forend, and a shell carrier system that turns this shotgun into a serious home-defense or duty-ready tool. The MultiCam finish and 18.5-inch barrel keep it compact and fast in tight spaces, while the clean-running gas system keeps cycling reliable through hard use. This is a shotgun for buyers who want a fighting gun, not a weekend plinker.
