Shop for Rock Ultra FS – 10mm online at

The Rock Island Armory Rock Ultra FS – 10mm 8+1 capacity is part of RIA’s Rock lineup of Series 70 M1911 semi-automatics. The FS means Full Size. Overall height is 5.5", overall width is 1.3" and overall length is 8.75". Unloaded weight is 2.5 pounds; this climbs to 2.87 pounds when the gun is loaded.

This semi is a single-stack, single-action, recoil-operated semi-automatic wrapped around a 1:16” twist ratio 5" barrel. Its bore is 6-groove button rifled.

The slide has classic M1911 looks. The top is barrel vaulted with dovetail cuts for Parkerized (anodized for wear and corrosion resistance) dovetail sights that are angled for snag-free unholstering. The front sight is a high-contrast red tube fiber optic. In back is an LPA MPS1 type adjustable rear sight. It is cantilevered and ramped, giving you improved usability and a better sight radius, which leads to higher accuracy.

Moving further back, you narrow vertical rear slide serrations. This gun also features a skeletonized loop hammer, nicely upturned beavertail, and an ambidextrous grip safety.

The frame, slide and other exposed parts are strong and hard high-grade SAE 4140 chromium-molybdenum alloy steel. The frame wears a black oxide finish while the slide is Parkerized.

Moving down you get to the adjustable overtravel stop skeletonized trigger. The trigger is triple ported with stacked trapezoids and has an adjustable overtravel stop. RIA factory sets trigger pull to 4 to 6 pounds.

Finally, the grips are wonderfully wavy and nicely textured white to black grayscale G10 polymer tactical grips. G10 is noted for its light weight and durability. Rock Island Armory’s experience pays off with its terrific lineup of M1911s that are solid, accurate and durable.
