Description
The AF1911 Romulus is what happens when a company decides the 1911 deserves a real update instead of a facelift. Alpha Foxtrot machines the frame and slide from SUS416 stainless steel, then coats everything in a polished black DLC finish that shrugs off holster wear and sweat while looking sharp doing it. The heart of the gun is a 4.25 inch bull ramped, threaded barrel with a 1:10 twist, button rifled to match grade standards. That bull profile adds weight right where you want it, keeping the muzzle planted so your dot barely moves between shots.
Optics Ready the Right Way
This version of the Romulus wears the MOS adapter slide cut, which is the one to get if you have not settled on a red dot yet. An RMSc footprint plate comes pre-installed and an RMR plate is included in the box, so most popular micro and full size dots will bolt right on. A Night Fision front sight gives you a bright, glowing reference point for co-witnessing or for the days you run irons only. The threaded muzzle leaves the door open for a compensator or other muzzle device down the road.
Built to Run Fast
The polymer grip module keeps weight reasonable and feeds from double stack 1911 style magazines, with a 17 rounder and a 20 rounder included. A factory installed flared magwell makes reloads forgiving under pressure, and the ambidextrous thumb safety works no matter which hand you shoot with. You still get the crisp single action trigger feel that keeps people coming back to this platform, along with an extended beavertail and an accessory rail up front for a light.
Where the Romulus Fits
This pistol splits the difference between a duty style setup and a competition build. It is at home in a nightstand safe with a light and dot attached, and just as comfortable running steel challenge stages on the weekend. For anyone who loves 1911 ergonomics but wants modern capacity and optics support, the Romulus makes a strong case for itself.

Frequently Asked Questions
What red dots will fit the AF1911 Romulus MOS adapter slide?
This model uses Alpha Foxtrot's MOS adapter cut, which supports both RMSc and RMR footprint optics. The RMSc plate comes pre-installed and an RMR plate is included in the box, so options like the Holosun 407K/507K, Shield RMSc, and Trijicon RMR family are all on the table. That covers most of the popular micro and full size dots without hunting down aftermarket plates.
What magazines does the Romulus use, and what capacity does it come with?
The Romulus is a double stack 1911 that feeds from 2011 style magazines, and it ships with one 17-round and one 20-round mag. The polymer grip module includes a factory installed flared magwell, which makes topping off quick even when your hands are moving fast. Spare mags are worth grabbing since this style of gun eats through ammo at the range.
Is the barrel on this AF1911 Romulus threaded?
Yes, this version features a 4.25 inch bull ramped barrel with a threaded muzzle. That gives you the option of adding a compensator or another muzzle device later, or just running the included thread protector for a clean look. The bull barrel profile also adds forward weight that noticeably tames muzzle flip in 9mm.
How does the finish on this Romulus hold up to regular carry and range use?
The frame and slide are machined from SUS416 stainless steel and coated in a polished black DLC finish. DLC is one of the toughest coatings out there for firearms, resisting holster wear, scratches, and corrosion far better than traditional bluing. Between the stainless base metal and the coating, this is a gun you can shoot hard without babying it.
