Key Features
- Bull Ramped, Threaded, Compensated Barrel: The integrated compensator and threaded barrel reduce muzzle rise and make suppressor or comp swaps quick — why it matters: faster follow-up shots and better control in competition or defensive use.
- Black Polished DLC Finish on SUS416: Diamond-like carbon coating on stainless steel resists corrosion and wear — why it matters: holds up to holster drag and humidity without rust, even after thousands of rounds.
- Double-Stack Magazine (17 & 20 Round): Factory includes two mags with extended capacity — why it matters: more rounds per reload without needing aftermarket basepads, and the 20-rounder gives you a backup for extended sessions.
- RMSC Optics Cut with MOS Adapter Plate: Direct-mount for RMSC footprint optics, plus plates for RMR — why it matters: you can run a red dot without extra machining, and the adapter system keeps zero shift minimal.
- Glowing Night Sights and Extended Beavertail: Tritium front/rear for low-light acquisition, plus an extended beavertail with memory bump — why it matters: reliable sight picture in darkness and a high grip that prevents hammer bite.
Who It’s For
This Romulus is built for shooters who want a compensated 1911 with modern capacity and optics compatibility — think USPSA competitors, home defenders who train often, and 1911 fans who don’t want to sacrifice round count. The bull barrel and DLC finish also appeal to those who shoot suppressed or run high-round-count drills in adverse conditions.
Pros & Cons
- Pro: Factory 20-round magazine is rare in production 1911s — saves you $40-$60 on aftermarket sticks.
- Pro: Ambi thumb safety and flared magwell make it lefty-friendly and fast to reload.
- Con: The polymer grip module feels less premium than aluminum or steel frames — some shooters prefer full-metal weight for recoil management.
- Con: The RMSC-cut limits direct-mount to smaller-footprint dots; larger RMR/SRO footprints require the adapter plate, adding height over bore.

The Romulus undercuts both competitors on price while offering a longer sight radius via the integrated comp and a higher capacity out of the box. The Zev OZ9C has a metal frame for more weight, but the Romulus’ DLC finish and threaded barrel give it an edge for suppressor use.
FAQ
Does the AF1911 Romulus come with an RMR plate, or only RMSC?
It includes both an RMSC plate and an RMR plate — the MOS adapter system covers both footprints out of the box.
Can I run a suppressor on the Romulus without the compensator?
Yes — the barrel is threaded (1/2×28, per the manufacturer), and the compensator is removable. You can direct-mount a suppressor after removing the comp.
Are the night sights tritium or fiber optic?
They’re tritium night sights — glowing in complete darkness, not fiber optic. Per AF1911 specs, they’re green front/rear.
Does the polymer grip module fit standard 1911 grips?
No — the grip module is proprietary and not compatible with standard 1911 grip panels. It’s designed for the double-stack magazine and flared magwell.
