Armscor Gi Rocki 51473 Std Fstb 45 5 8R Blk

The Rock Island Armory GI Standard is a no-nonsense 1911 chambered in 45 ACP that stays true to the original specification that made the platform legendary. Built on Rock Island's proven manufacturing standards, this 5-inch barreled pistol delivers the classic lines and ergonomics that shooters still trust for duty, sport, or personal protection. Whether you're running it from a quick-draw holster or putting rounds downrange at the club, the GI Standard gives you a timeless design without the premium price tag.

The fixed low-profile GI-type sights are straightforward and fast to use—there's no fiddling with adjustments or complex optics mounts. The smooth rubber grips and slim frame profile make this a comfortable all-day carry or range gun, and the 5-inch threaded barrel provides the balance and velocity the 1911 design is known for. The black parkerized finish is tough, durable, and non-reflective—built for actual use, not the safe. Rock Island equips every GI Standard with a crisp factory trigger breaking in the 4- to 6-pound range, so you get a shootable gun straight from the box.

This is a working pistol for shooters who appreciate function over flash: 8 rounds of 45 ACP reliability in a compact footprint that fits proven holsters and gear from decades of 1911 adoption. Maryland-compliant and ready to shoot.

Frequently Asked Questions

What's the barrel? Is it threaded?

Yes. The GI Standard features a 5-inch threaded barrel, which matches the length and profile of the original GI-issue 1911 while allowing you to attach a suppressor or muzzle device if needed.

Is this 1911 good for carry and concealment?

At 2.47 lbs and 9.125 inches overall, the GI Standard is a traditional full-size frame 1911. It's not a compact model, so it works best for duty carry, waistband carry, or range use rather than deep concealment. The fixed sights and slim rubber grips make it very holster-friendly.

What sights come on this pistol?

The GI Standard is equipped with fixed low-profile GI-type sights—a front sight mounted on the slide and a rear sight in a dovetail cut. These are traditional combat sights designed for fast target acquisition and are not adjustable.

Will this work with standard 1911 holsters and magazines?

Yes. The Rock Island GI Standard is built to 1911 specification, so it accepts standard magazines and fits into gear designed for any mil-spec 1911 profile.
