RIA 22TCM Conversion Kit for A1 1911 9mm - 10-Round Magazine

The RIA 22TCM conversion kit for A1 1911 9mm is a complete barrel and sight package that lets you transform a government-frame 1911 into a dedicated .22 TCM shooter. Rock Island Armory engineered this kit with a fully supported ramped barrel designed to handle the cartridge's demands, making it a practical way to add a high-velocity pistol option to your collection without buying an entirely new gun. If you reload, shoot competitively, or just want to explore what .22 TCM can do, this conversion gives you that flexibility on a platform you probably already know how to run.

The kit arrives with a pair of sights: an adjustable rear two-dot design and a fiber optic front sight for quick target acquisition in varied light. The rear slide features machined classic A1 serrations, keeping the look period-correct while you're running modern ballistics. A 10-round magazine is included, sized for the .22 TCM cartridge. The barrel measures 4.5 inches, and the overall length comes in at 7.24 inches—compact enough for carry or sport shooting.

Keep in mind: this is a precision conversion component. Rock Island recommends registered gunsmith fit and finish, so plan to have a qualified smith handle installation to ensure reliable function and safety. The kit fits any government-frame 1911, but proper assembly matters with conversions.

Frequently Asked Questions

Will this conversion kit fit my 1911?

The kit is designed to fit any government-frame 1911. If you have a standard-frame (non-government) 1911, compatibility may differ. Check your frame type before ordering, or consult with a gunsmith.

What's included in the kit?

The kit includes the barrel, adjustable rear two-dot sight, fiber optic front sight, and a 10-round magazine sized for .22 TCM. Installation labor is not included; you'll need a registered gunsmith to fit and finish.

Do I need a gunsmith to install this?

Yes. Rock Island Armory specifies that registered gunsmith fit and finish is required for proper assembly and function. Installation is not a user-level task.

What is .22 TCM and why would I shoot it?

The .22 TCM is a high-velocity pistol cartridge. Shooters choose it for hunting, sport shooting, and handloading experimentation. It offers ballistics distinct from standard pistol cartridges. Ammunition availability varies by region, so verify local supply before committing.
