The Alpha Foxtrot AF1911 Romulus pistol in 9mm with a 4.25-inch bull barrel (brand part no. AA39X1CID-XDBK19) delivers full-size performance built on Alpha Foxtrot’s modern 2011-style engineering, offering a longer sight radius than the shorter Romulus variant. Alpha Foxtrot finishes the frame and slide in black polished DLC, and Night Fision sights back up the RMSC/RMR optics cut for red dot mounting. The pistol includes a Picatinny rail, an ambidextrous thumb safety, and a flared magwell for faster reloads, and ships with an MOS adapter plate, RMSC and RMR mounting plates, and 17-round and 20-round magazines. Among full-size double-stack semi-auto handguns, this AF1911 Romulus 4.25-inch configuration favors shooters who want maximum sight radius with 2011-style capacity.
