Rock Island RIA TAC Ultra MS Combo 9mm/22TCM9R 17rd

About this product

The Rock Island RIA TAC Ultra MS Combo is a 1911-style double-stack pistol chambered in 9mm with an included 22TCM9R conversion kit that delivers platform versatility through factory-supported caliber switching. This Steel-framed pistol maintains classic 1911 ergonomics while accommodating modern high-capacity demands with its 17+1 round magazine. As an armorer with over a decade evaluating Title II weapons systems, I appreciate how this package addresses both training economy and terminal performance in one purchase.

What is the Rock Island RIA TAC Ultra MS Combo used for?

This pistol serves as a dual-role platform for both high-volume 9mm training and high-velocity 22TCM9R applications, with the conversion process taking approximately 90 seconds using only a punch tool. The 22TCM9R cartridge achieves velocities nearing 2,000 fps from this 5-inch barrel, making it effective for varmint control or tactical drills where barrier penetration is desired. For sustained range use, the 9mm configuration provides affordable practice with identical manual of arms.

How does the Rock Island RIA TAC Ultra MS Combo compare to the Stevens 334 Rifle?

The RIA TAC Ultra offers rapid caliber switching between pistol rounds, while the Stevens 334 Rifle in .308 Win delivers superior long-range energy transfer at 300+ yards. Where the Stevens 334 produces consistent 1.5 MOA groups with match ammunition, the RIA TAC Ultra achieves combat-effective accuracy of 3-4 inches at 25 yards with both calibers. The pistol excels in close-quarters versatility, while the rifle dominates in precision engagements beyond 100 meters.

What does it weigh and what are the dimensions?

Unloaded weight measures 42 ounces due to its all-steel construction, with overall length of 8 inches and height of 5.75 inches including the magazine. The 5-inch barrel features a 1:16 twist rate optimized for stabilizing both 9mm and 22TCM9R projectiles, while the grip circumference measures 2.75 inches—substantial but manageable for medium to large hands. These dimensions place it squarely in full-size duty pistol territory, comparable to a SIG P226 but with 1911-style controls.

Who is this NOT for?

Concealed carry permit holders seeking a discreet daily weapon should avoid this platform, as its 42-ounce weight and 8-inch length exceed practical concealment dimensions. Shooters with hand strength limitations may struggle with the 5.5-pound single-action trigger pull, which requires deliberate engagement compared to striker-fired alternatives. Additionally, those operating in jurisdictions with magazine capacity restrictions cannot utilize the 17-round magazines without modification.

What's in the box?

The package includes one complete pistol in 9mm configuration, one 22TCM9R conversion barrel assembly, one 17-round 9mm magazine, and appropriate paperwork—notably missing additional magazines for the alternate caliber. The conversion process requires only a barrel swap and functions with the existing slide and magazine, though dedicated 22TCM9R magazines would improve reliability. At this price point, the exclusion of a second magazine or caliber-specific optics plate feels like a missed opportunity.

Is the Rock Island RIA TAC Ultra MS Combo worth it at $799?

Yes, for shooters requiring both training economy and specialized terminal performance without maintaining multiple firearms. The 22TCM9R conversion alone retails for $250-$300 separately, making the bundled pricing effectively $500 for the base pistol—comparable to Turkish imports but with better regulatory documentation. However, budget-conscious buyers preferring shotgun versatility might prefer the Stevens 555 Sporting O/U for its simpler mechanics and broader ammunition compatibility.
