The Rock Island Armory Rock Standard CS – 45 ACP is part of RIA’s Rock lineup of M1911 semi-automatics based that uses the M1911 Series 70 as its foundation. This semi-automatic is a 7+1 single-stack, single-action, recoil-operated pistol. The CS is RIA’s delightfully efficient and logical shorthand for Compact Size.

The central measure is the 3.5" length of its button rifled barrel that’s supported by a full-length guide rod. The barrel’s 6-grooves spiral inside the bore at a 1:16” twist ratio.

The pistol is nice looking thanks to its detailing and classic features. For instance, it has seven nicely spaced slide serrations that tilt forward at back. The frame, slide, etc., are strong and hard high-grade SAE 4140 chromium-molybdenum alloy steel. Both frame and slide are then Parkerized for durability.

Otherwise, the gun echoes its Rock siblings with a familiar upturned beavertail, skeletonized hammer that loops in an oval, adjustable overtravel stop skeletonized trigger and fixed dovetailed sights that are angled for snag-free unholstering.

Both sights are also Parkerized and thus anodized for wear and corrosion resistance. The rear sight is cantilevered and ramped for an extended sight radius, which leads to higher accuracy. You also get an ambidextrous grip safety that feels just right.

The trigger is beautiful, triple ported, and has an adjustable overtravel stop. The factory-set trigger pull is 4 to 6 pounds. Unloaded weight is 2.5 pounds. Overall height is 5.125" and overall length is 7.125".

Finally, the grips are double diamond checkered matte black rubber. This means they have the up and down arrowhead shaped surrounds around the flat-head grip fastening screws and then a diamond texturing in between. These grips complete an ensemble that simultaneously marries classic lines with modernity of assembly and features.

Rock Island Armory’s experience pays off with its terrific lineup of M1911s that are solid, accurate, affordable and durable.
