Description
The AF AA39X1QIG-XDBK19 AF1911-ROMULUS 3.5″ 17/20R is a factory-new semi-auto handgun built for shooters who demand a reliable, high-capacity 1911 platform without the custom-gunsmith wait. Chambered in 9mm, this Romulus model ships with two magazines—a 17-round and a 20-round—giving you extended firepower straight out of the box. The 3.5-inch barrel keeps it compact for carry or range use, while the black finish and full-size grip frame deliver the classic 1911 feel with modern capacity. Priced at $1400.56, it competes directly with semi-custom builds from Zev and Agency Arms.

Key Features
- Extended Magazine Capacity: Comes with both a 17-round and a 20-round magazine, giving you up to 20+1 on tap. Why it matters: you get Glock-level capacity in a 1911 frame without needing aftermarket base pads or extensions.
- 3.5-Inch Barrel: Short enough for concealed carry but long enough to maintain ballistic velocity and sight radius. Why it matters: balances shootability with concealment, making it a true do-it-all 1911.
- Full-Size Grip Frame: Accommodates double-stack magazines while retaining the classic 1911 grip angle and thumb-safety placement. Why it matters: you don’t have to retrain your manual of arms to run high-capacity 9mm.
- Black Oxide Finish: Corrosion-resistant and low-glare, suitable for everyday carry and range use. Why it matters: holds up to holster wear and sweat without rusting like a raw stainless gun might.
- Factory-Built Reliability: Assembled by AF with a match-grade barrel and tuned extractor. Why it matters: you get consistent ejection and feeding without sending it off to a gunsmith.
Who It’s For
This handgun is built for shooters who want a high-capacity 1911 that doesn’t require a second mortgage or a year-long wait list. It’s ideal for competition shooters who need 20-round stage loads, concealed carriers who want a shorter barrel with a full grip, and 1911 purists who refuse to switch to a polymer striker-fired gun. If you’ve been looking at double-stack 1911s from STI or Bul Armory but want something under $1500, this Romulus fills that gap.
Pros & Cons
- Pro: Ships with two high-capacity magazines (17 and 20 rounds) — no extra purchase needed.
- Pro: 3.5″ barrel makes it easier to carry AIWB or strong-side without printing.
- Pro: Classic 1911 ergonomics with double-stack firepower.
- Con: The black oxide finish is durable but not as hard-wearing as a DLC or Cerakote coating — expect holster wear over time.

FAQ
Does the AF1911-Romulus accept standard 1911 grips?
No — because it uses a double-stack frame, the grip panels are specific to this model. You cannot install standard 1911 thin grips or aftermarket grip panels designed for single-stack frames.
What holsters fit the 3.5-inch barrel version?
Most holsters made for full-size 1911 frames with a 3.5- to 4-inch barrel will work. Look for holsters listed for the “Romulus” or “AF1911” specifically. The trigger guard profile is similar to a standard 1911, so many kydex and leather holsters fit without modification.
Can I use standard 1911 magazines in this gun?
No — this handgun requires double-stack 9mm 1911 magazines. The 17- and 20-rounders included are proprietary to AF. Standard single-stack 1911 magazines will not lock in or feed reliably.
Is the AF1911-Romulus legal in all 50 states?
It ships to all 50 states, but some states (California, New York, Massachusetts, etc.) have magazine capacity limits. The 20-round magazine may be restricted in those states. We ship with pinned or reduced-capacity magazines where required by law.
