About this product
The Rock Island Rock Ultra FS 1911 Pistol Combo in 9mm/22TCM with a 5-inch barrel and black Parkerized finish gives you two calibers in one proven platform. This combo comes with an accessory barrel for the 22TCM round, letting you switch between a soft-shooting 9mm and a high-velocity 22TCM with just a quick barrel swap. It ships with a 10-round magazine, features a 70 series design, and includes ambidextrous safety, fiber optic front sight, and G10 grips. At $641.35, it is a solid buy for anyone wanting a versatile 1911 without buying two separate pistols.

Key Features
- Two caliber barrels included – WHY IT MATTERS: You get the 9mm barrel installed and a separate 22TCM barrel in the box, so you can shoot two different rounds out of one pistol. The 22TCM hits harder than a .22 Magnum but with less recoil than a standard 9mm.
- Black Parkerized finish – WHY IT MATTERS: This matte finish resists corrosion and glare, making it a good choice for range use or carry. It holds up well to holster wear over time.
- Fiber optic front sight – WHY IT MATTERS: The bright green or red fiber optic rod picks up ambient light for fast target acquisition, especially in indoor ranges or low-light conditions.
- Ambidextrous safety – WHY IT MATTERS: Left-handed shooters can engage the safety without breaking their grip, and right-handed shooters get a more natural thumb placement.
- G10 grips with skeletonized hammer and trigger – WHY IT MATTERS: The G10 material gives you a positive grip texture even with sweaty hands, while the skeletonized parts reduce overall weight and give a crisper trigger pull.
Who It's For
This combo is built for shooters who want one gun that does double duty. If you are a new gun owner looking to try different calibers without buying two pistols, this is a smart starting point. It also fits experienced 1911 fans who want a lightweight training round in 9mm and the option to step up to the 22TCM for varmint control or plinking. The ambidextrous safety makes it a natural fit for left-handed shooters as well.
Pros and Cons
- Pro: Two calibers in one package at a price lower than buying two separate 1911s.
- Pro: Fiber optic front sight is bright and easy to pick up.
- Pro: Ambidextrous safety works for both left and right-handed shooters.
- Con: The 22TCM barrel requires a separate magazine (not included) for reliable feeding in that caliber. Per Rock Island specs, the 22TCM uses a different magazine than the 9mm, so you will need to pick up a 22TCM mag if you plan to shoot that round regularly.
- Con: The Parkerized finish, while durable, is not as slick as a blued or stainless finish for quick holster draws.

FAQ
Does the Rock Island Rock Ultra FS 1911 Combo come with both barrels installed?
No. The pistol ships with the 9mm barrel installed. The 22TCM barrel is included in the box as an accessory barrel. You will need to swap them yourself, which takes about 30 seconds with a basic field strip.
What magazines are compatible with the 22TCM barrel?
The 22TCM round requires its own dedicated magazine. The included 10-round magazine is for 9mm only. You will need to purchase a Rock Island 22TCM magazine separately. They typically hold 15 rounds and are available through most 1911 parts dealers.
Is this pistol accurate out of the box?
Yes. The 5-inch barrel and 70 series design give you a solid foundation for accuracy. Expect 2- to 3-inch groups at 25 yards with quality ammunition. The fiber optic front sight helps with consistent sight alignment.
Can I shoot +P ammunition through this pistol?
Per Rock Island specs, the Rock Ultra FS is rated for standard pressure 9mm ammunition. While occasional +P loads are unlikely to cause damage, regular use of +P may accelerate wear on the barrel and recoil spring. Stick with 115- or 124-grain standard pressure for best reliability.
