The Rock Island Armory USA 1911 A2 Tac Ultra AOS is a modern take on the classic 1911 platform, chambered in .45 Auto and built for shooters who want proven single-action reliability with tactical versatility. If you're looking for a 1911 that bridges traditional design with contemporary features—whether for range time, home defense, or competitive shooting—this five-inch barrel variant delivers the stopping power and ergonomics that have made the .45 ACP a cornerstone of American handgun culture for over a century.
Rock Island Armory has engineered this model to balance the 1911's legendary trigger control and accuracy with practical modern touches. The 13-round magazine capacity gives you more rounds on tap than a standard single-stack, while the 5-inch barrel strikes the middle ground between a commander-length carry gun and a full-size target pistol. The AOS (Accessory Optics System) slide is pre-cut to accept modern red-dot sights, letting you integrate current optic technology without gunsmithing. Glock-pattern sights keep the sight picture straightforward and replacement parts accessible.
Built in the Philippines under Armscor's quality standards and imported by Armscor USA, this 1911 A2 combines decades of 1911 refinement with the durability you'd expect from a production that's earned solid footing in the U.S. market. The 4–6 lb. trigger pull is clean enough for precision work, and the semi-automatic action cycles the potent .45 ACP round reliably. At 2.5 pounds, it's substantial enough to manage recoil without becoming a burden for extended sessions.
This is a full-sized defensive and range pistol in a proven cartridge—not a compact carry gun. Choose it if you value the classic 1911 manual of arms, want a larger grip for a solid purchase, and aren't constrained by ultra-concealability. The 8.74-inch overall length and 1.43-inch width confirm it: this is a full-frame platform.
| Caliber | .45 Auto (ACP) |
| Magazine Capacity | 13 rounds (plus 1 in chamber) |
| Barrel Length | 5.05 inches |
| Overall Length | 8.74 inches |
| Width (Slide) | 1.43 inches |
| Height | 5.77 inches |
| Weight | 2.5 lb |
| Action | Semi-automatic, single-action |
| Front Sight | Glock-pattern |
| Rear Sight | Glock-pattern |
| Trigger Pull | 4–6 lb |
| Frame Type | 1911 A2 Tac Ultra AOS |
Yes. The AOS (Accessory Optics System) slide is pre-milled to accept optic mounting plates designed for the 1911 platform. You'll need to verify your specific red-dot footprint matches the cut, but the slide is ready for modern sights out of the box—no gunsmithing required.
This model ships with a 13-round magazine, which is higher than the traditional 7- or 8-round single-stack 1911 magazines. The 13+1 capacity (13 in the mag, 1 chambered) is a meaningful upgrade if round count matters to your use case.
At 8.74 inches long, 1.43 inches wide, and 2.5 pounds, this is a full-size 1911. It's better suited to range shooting, home defense, or duty carry than to deep-concealment carry. The five-inch barrel and full-size grip prioritize shootability over concealment.
The 1911 A2 Tac Ultra AOS ships with Glock-pattern front and rear sights. These are durable, fast-acquiring combat-style sights, and Glock-pattern replacement sights are widely available if you ever want to swap them.
