Rock Island Armory Rock Ultra FS Combo 9mm .22 TCM

Description

The Rock Island Armory Rock Ultra FS Combo is for the shooter who wants two distinct calibers in one reliable 1911 platform. This package gives you a 9mm pistol ready for the range or defense, plus a .22 TCM barrel and magazine for high-velocity plinking. It’s a versatile workhorse that lets you switch between two very different shooting experiences with a simple barrel swap.

Key Features

• Dual-Caliber Kit: Comes complete with a 5″ 9mm barrel and a 5″ .22 TCM barrel, recoil spring, and a dedicated 9-round magazine for each caliber. Everything you need is in the box.
• Full-Size 1911 Frame: Built on a solid steel frame with a full-length guide rod and a beavertail grip safety. It’s a classic, heavy platform that soaks up recoil, making the 9mm feel soft and the .22 TCM a flat-shooting laser.
• Adjustable Target Sights: The fully adjustable rear sight is crucial for getting the most out of the .22 TCM’s trajectory. After decades of testing, I know you’ll need to dial it in for that little screamer of a round.
• Aggressive Grip & Skeletonized Trigger: The checkered grips and trigger provide a solid, non-slip hold. The trigger breaks cleanly around 5-6 lbs, which is perfectly serviceable for a pistol in this price range.

Honest Assessment

Pros: The value here is exceptional. You’re getting two capable pistols for the price of one basic 1911. The .22 TCM is a legitimate blast to shoot—minimal recoil, a huge fireball, and it’s incredibly accurate. The build quality is solid for the money; it’s a straightforward, no-frills 1911 that works.

Cons: The .22 TCM ammo is a niche cartridge. It’s not on every store shelf, so you’ll likely be ordering it online. I’ve also seen firsthand that the finish is utilitarian—it’s a parkerized coating that will show wear with hard use. Don’t expect a showpiece gloss.

Who Should Buy This

This combo is perfect for the tinkerer or the budget-minded enthusiast who wants maximum versatility. If you enjoy the 1911 platform and want to experiment with a wildcat cartridge without buying a whole new gun, this is your ticket. It’s also a great choice for a shooter who wants a 9mm for practical use but craves a low-cost, high-fun factor option for the range.

FAQ

Is .22 TCM ammo easy to find?

It’s becoming more common, but it’s not as ubiquitous as 9mm. You’ll have the best luck online or at larger sporting goods stores. Keep a supply on hand.

How difficult is the caliber conversion?

It’s straightforward. Field strip the pistol, swap the barrel and recoil spring, and use the correct magazine. The whole process takes about 60 seconds once you’re familiar with it.

Can you use 9mm in the .22 TCM magazine?

No. You must use the dedicated magazine for each caliber. The feed lips and follower are designed for the specific cartridge shape.

Is this a good first 1911?

It can be, especially if you’re mechanically inclined. You get two guns in one, which is a great way to learn the platform. Just be prepared for the added step of managing two different types of ammunition.
