The Alpha Foxtrot AF1911-Romulus is a 1911-pattern pistol chambered in 9mm Luger (brand part no. AA39X1EIB-XDBK19) built around a 5-inch threaded barrel and a direct-mount RMSc-footprint slide. Alpha Foxtrot machines the frame, slide, and barrel from SUS416 stainless steel, then polishes and finishes every surface in black DLC for corrosion resistance and a clean, low-glare look. The direct RMSc mount means a Trijicon RMSc-footprint red-dot bolts straight to the slide with no adapter plate, and the match-grade button-rifled barrel with a 1:10 right-hand twist is built for consistent, repeatable accuracy. It ships with both 17-round and 20-round magazines, giving the shooter a choice between standard and extended capacity for the same pistol.
