Alpha Foxtrot Romulus | 9mm | 3.5" | Threaded | Polished DLC | MOS | 20rd Pistol

The Alpha Foxtrot AF1911 Romulus (MPN: AA39X1QIB-PDBK19) is a double-stack 1911-style pistol built from SUS416 stainless steel with a 3.5" threaded bull barrel and a textured polymer grip module. This exact 9mm model pairs a Polished Black DLC treatment with the threaded barrel configuration.

The threaded bull barrel is the defining feature of this configuration while the rest of the pistol retains the Romulus double-stack architecture. The MOS adapter system supports RMR- and RMSc-pattern optics through the supplied plate system. The frame includes a Picatinny accessory rail, flared magwell, front and rear slide serrations, and an ambidextrous thumb safety. Alpha Foxtrot lists one 17-round and one 20-round magazine with the 9mm Romulus.
