Alpha Foxtrot AF1911 Romulus .45 ACP Pistol, Bull Barrel, 4.25-inch

The Alpha Foxtrot AF1911 Romulus is a 1911-pattern pistol chambered in .45 ACP (brand part no. AA39X4CID-XDBK13) built around a 4.25-inch stainless steel bull barrel. Alpha Foxtrot machines the slide and frame from stainless steel and finishes every surface in black DLC, giving this Romulus build the corrosion resistance and low-glare look serious carry and duty pistols need. The optic-ready, serrated slide is cut to accept both RMR- and RMSc-footprint red-dot sights directly, and a beavertail on the frame protects the hand from slide bite during recoil. A full-length Picatinny rail up front mounts a weapon light, making this Romulus a genuine duty-capable .45 ACP 1911 rather than a range-only pistol.
