Rock Island Armory RIA Tac Ultra FS .45 ACP 8+1
About this product
The Rock Island Armory RIA Tac Ultra FS .45 ACP 8+1 is a full-size, steel-frame 1911 pistol designed for practical shooting applications. It maintains classic 1911 ergonomics while incorporating modern features like an accessory rail and adjustable sights for enhanced versatility. This firearm bridges the gap between traditional design and contemporary tactical requirements.
What is the Rock Island Armory RIA Tac Ultra FS used for?
This pistol serves as a reliable duty, competition, and range firearm with modern tactical enhancements. The 8+1 capacity .45 ACP chambering provides sufficient firepower for defensive scenarios, while the Novak/LPA sight system ensures quick target acquisition. Its 39-ounce weight and full-size frame make it suitable for shooters preferring a substantial platform over lighter polymer alternatives.
How does the Rock Island Armory RIA Tac Ultra FS compare to a Springfield Armory TRP Operator?
The RIA Tac Ultra FS offers similar features at approximately half the price of the $1,300 Springfield TRP Operator. While the TRP features match-grade barrel and tighter tolerances, the RIA provides 90% of the performance for shooters needing a reliable .45 ACP platform without premium pricing. The RIA's Parkerized finish wears more visibly than the TRP's more durable treatment.
What does it weigh and what are the dimensions?
This pistol weighs 39 ounces unloaded with dimensions measuring 8.75 inches in length, 5.5 inches in height, and 1.25 inches in width. The 5-inch barrel provides optimal ballistic performance for .45 ACP, while the steel frame contributes to manageable recoil compared to lighter platforms like the Stevens 334 rifle in .308 Win.
Who is this NOT for?
This firearm is not ideal for concealed carry due to its full-size dimensions and 39-ounce weight. Shooters seeking lightweight polymer frames or higher capacity should consider modern striker-fired options. Those requiring precision bullseye competition performance may find the factory trigger lacks the refinement of custom 1911 builds.
What's in the box?
The package includes one 8-round magazine, cable lock, and owner's manual. Unlike some competitors, it does not include additional magazines or holster options. The single magazine configuration keeps costs down but requires additional purchases for optimal functionality, similar to the basic packaging of the Stevens 555 Sporting shotgun.
Is the Rock Island Armory RIA Tac Ultra FS worth it at $638?
At $638, this pistol represents exceptional value for a steel-frame 1911 with tactical features. The price undercuts comparable models by $300-$500 while maintaining reliable functionality. For shooters wanting a .45 ACP platform with modern amenities without custom shop pricing, this offers one of the best cost-to-performance ratios on the market.

Frequently asked questions
- Is it compatible with standard 1911 magazines?
- Yes, it accepts standard 1911 .45 ACP magazines with 7-8 round capacity. Some aftermarket 10-round magazines may require feed ramp modification. Wilson Combat and Chip McCormick magazines function reliably in testing.
- Does it fit standard 1911 holsters?
- Most standard 1911 holsters accommodate this model, but the accessory rail adds 0.25 inches of width. Kydex holsters for railed 1911s provide the best fit. Leather may require 2-3 weeks of break-in for proper retention.

- Does this work with suppressor-height sights?
- The Novak/LPA sight combination accepts suppressor-height replacements from Dawson Precision and others. Co-witness requires sights measuring 0.315 inches tall for standard suppressor alignment.
