Key Features
- Compensated Bull Barrel – The 4.25-inch barrel includes an integral compensator that reduces muzzle rise and helps you stay on target for faster follow-up shots. This matters in competition or defensive drills where split times count.
- Double-Stack 9mm Magazine – Standard 1911s hold 7-8 rounds; the Romulus gives you 17+1 rounds of 9mm without a grip that feels like a 2×4. That matters when you want high capacity in a familiar 1911 manual of arms.
- Optics-Ready with MOS Adapter – The slide is cut for RMR and Holosun footprints, and includes adapter plates. You can mount a red dot without sending the slide to a machine shop. This matters for shooters who want faster target acquisition.
- Injected Polymer Grip with Flared Magwell – The grip module is lightweight, textured, and includes an assembled flared magwell for faster reloads. This matters when you’re running drills or shooting USPSA and need to shave seconds off your reloads.
- Extended Beavertail & Thumb Safety – The extended beavertail prevents hammer bite, and the extended thumb safety gives you positive engagement without digging into your hand. This matters for high-round-count sessions where comfort and control are critical.
Who It’s For
The Alpha Foxtrot AF1911 Romulus is for the 1911 shooter who wants modern capacity and a compensated barrel without switching to a striker-fired platform. It’s for competitors who shoot USPSA or IDPA and need 17+1 rounds in a 1911 frame. It’s also for anyone who appreciates stainless steel construction, DLC durability, and an optics-ready slide that doesn’t require aftermarket milling.
Pros & Cons
- + High capacity (17+1) in a 1911 frame
- + Integral compensator reduces muzzle rise
- + Optics-ready with included RMR/Holosun plates
- + DLC finish on stainless steel for corrosion resistance
- – The injected polymer grip won’t appeal to purists who want all-metal frames. Some shooters prefer the feel of a steel or aluminum grip module.

FAQ
Does the Alpha Foxtrot AF1911 Romulus come with a compensator?
Yes. The 4.25-inch barrel is a compensated bull barrel with an integral compensator machined into the barrel itself. It’s not a threaded adapter – it’s part of the barrel assembly.
What optics will fit the Romulus slide?
The slide is cut with an MOS adapter system. Included adapter plates fit Trijicon RMR (and RMRcc) and Holosun 407C/507C/508T footprints. You can mount any of those optics directly using the included hardware.
Is the AF1911 Romulus compatible with standard 1911 holsters?
Not always. Because of the double-stack grip width and the integrated compensator, many standard 1911 holsters won’t fit. Look for holsters specifically designed for double-stack 1911s or the AF1911 platform. Some universal or “1911 commander” holsters may work, but test before carrying.
What is the magazine capacity of the Romulus?
Standard magazine capacity is 17 rounds of 9mm. The pistol ships with one 17-round magazine. Aftermarket extended baseplates are available from Alpha Foxtrot for 20+ round options.
The Alpha Foxtrot AF1911 Romulus 9mm 4.25in Comp is available now at $1,400.44. According to industry data, double-stack 1911s now account for roughly 12% of the 1911 market, driven by demand for higher capacity in a familiar platform. This pistol delivers that without sacrificing the classic 1911 trigger or manual of arms.
