Description

The 1911 crowd has been asking for years: why do all the modern double-stack builds skip the 45? Alpha Foxtrot answered with this version of the AF1911 Romulus, a hammer-fired double-stack chambered in the cartridge the platform was born to run. You get 13+1 rounds of 45 ACP in a pistol machined from SUS416 stainless steel, with both the slide and frame wearing a polished black DLC finish that shrugs off wear and corrosion while keeping the look clean and businesslike.

What Sets This Romulus 45 Apart

The 4.25 inch bull barrel is Alpha Foxtrot's ultra-match 416R, button rifled with a 1:10 right-hand twist, and the extra mass up front does a nice job soaking up the 45's push. The slide carries serrations front and rear for positive manipulation, plus an MOS optic cut that works with both RMR and RMSc footprint red dots thanks to the included adapter plates. That's a real convenience, since the standard RMSc-only cut on other Romulus models won't take an RMR. Glowing night sights come installed, so you're covered before you ever mount a dot.

Built Like a Modern AF1911 Should Be

The grip module is injected polymer with a flared magwell for quicker reloads, paired with an extended beavertail that lets you get a high, comfortable hold without hammer bite. An extended slide release, ambidextrous thumb safety, and a Picatinny accessory rail round out the controls, so lefties and light users are both taken care of. The trigger is classic single action 1911, with the crisp wall and short reset that keeps people coming back to this platform decade after decade.

Alpha Foxtrot builds these in the USA, and the Romulus line has earned a following for slide-to-frame fit and trigger quality that punch above their bracket. If you have been waiting for a double-stack 1911 that still speaks fluent 45 ACP, this one deserves a spot on your short list, whether that means range days, competition, or a full-size defensive setup.

Frequently Asked Questions

What red dot optics will fit the AF1911 Romulus 45 ACP?

This model uses Alpha Foxtrot's MOS adapter system and ships with plates for both the Trijicon RMR and RMSc footprints. That covers a huge range of popular optics, including most Holosun and Shield pattern dots. Keep in mind the factory night sights sit low, so co-witnessing with a mounted dot generally is not possible without taller aftermarket irons.

Is this Romulus a true 1911 action?

Yes, it is a single-action, hammer-fired design with the traditional 1911 grip safety and an ambidextrous thumb safety. The trigger is a flat-face style with a crisp break and short reset, which is exactly what draws people to the platform. The big difference from a classic 1911 is the double-stack magazine and modern polymer grip module.

How many magazines come with the Romulus 45 ACP, and what capacity are they?

This 45 ACP version ships with two 13-round double-stack magazines, giving you 13+1 total capacity with one in the chamber. That is a serious jump over the 7 or 8 rounds you get from a single-stack 1911 in the same caliber.

Is the 4.25 inch barrel on this AF1911 Romulus compensated or threaded?

No, this particular model features a standard bull barrel with no compensator or threading. The heavy bull profile adds weight at the muzzle, which helps tame recoil and muzzle flip on its own. Alpha Foxtrot does offer separate Romulus variants with compensated and threaded barrels if that is what you are after.
