Description
The Alpha Foxtrot Romulus 4.25 promo pairs the mid-length compensated Romulus with five 20-round magazines and an Alpha Foxtrot soft case. It is the configuration most shooters end up wanting anyway: long enough for a usable sight radius, short enough to carry, and compensated so it recovers like a bigger gun. Frame and slide are SUS416 stainless steel under a satin DLC finish.
What the Promo Package Includes
AF1911-Romulus with a 4.25-inch bull ramped compensated barrel, 20+1 in 9mm Luger.
Five 20-round magazines, which covers a full club match without borrowing or buying spares.
Alpha Foxtrot soft case sized for the pistol and the magazines.
Everything in the Alpha Foxtrot Romulus 4.25 promo is factory packed, not assembled at the shop.
Compensated, Optic Ready, Ambidextrous
Factory compensator bleeds gas upward so the muzzle drops back onto target between shots.
MOS cut in the slide supports the RMR and the RMSc footprints, covering most red dots on the market.
Satin DLC over SUS416 stainless on frame and slide, hard and low friction without the glare of a polished finish.
Serrated slide, extended beavertail and a Picatinny rail on the dust cover.
Part number AA39X1CIG-XDBK20-PROM.

The 4.25-inch length is where most double-stack 1911 buyers land, and the reason is simple arithmetic. Against the 5-inch you lose a little sight radius and gain real concealability. Against the 3.5-inch you gain dwell time and muzzle weight, which the compensator then amplifies. Add five magazines and a case and the usual post-purchase shopping list mostly disappears.
Why it is worth considering
- Five 20-round magazines and a soft case included.
- Factory compensator, no gunsmithing and no separate muzzle device.
- MOS cut supports both common red dot footprints.
- Satin DLC finish cuts glare compared with a polished slide.
- SUS416 stainless throughout, built in America.
Who it suits
Competitors who need magazines on day one and carriers who want the mid length will both be served here. The Alpha Foxtrot Romulus 4.25 promo also makes a sensible first double-stack 1911, since nothing else has to be bought before the first match. As with any comped pistol, expect more noise and gas to the sides than a plain muzzle gives.

Other Ways to Buy a Romulus
Alpha Foxtrot builds the Romulus in 3.5-inch, 4.25-inch and 5-inch lengths, with standard, threaded or compensated barrels and with a polymer or machined aluminum grip module. The 3.5-inch promo package is the same bundle in a shorter slide, and the 4.25-inch aluminum grip bundle swaps the polymer module for machined metal. For a full-size gun with no comp, compare the 5-inch DLC black build or the 4.25-inch threaded model. Model details are published by the maker at Alpha Foxtrot.
Compensators reward heavier bullets, because more gas means more downward push at the muzzle. A 124-grain jacketed hollow point works well for carry and runs the comp properly, with 115-grain full metal jacket saved for practice volume. All firearm orders ship to a licensed FFL dealer for transfer, and MAG5 Firearms will coordinate the paperwork with the dealer of your choice.
One practical note on storage: five loaded 20-round magazines add real weight to a range bag, and leaving them loaded long term is fine for modern springs but worth rotating if the gun sits in a safe for months at a stretch. The supplied soft case keeps them together and out of contact with the slide, which saves the finish from the scuffing that loose magazines cause in a shared bag.
