The Rock Island Armory Rock Standard ECS 1911 in .45 ACP, stainless (brand part no. 51868), is a compact-size 1911 built in the traditional Series 70 design with Rock Island Armory’s production and engineering standards. Armscor/Rock Island Armory chambers the pistol in .45 ACP with a 7-round capacity and a 3.63-inch button-rifled barrel, and the slide carries rear slant serrations over a traditional roll-over ejection port. The matte stainless slide and frame use SAE 4140 high-grade steel, with parkerized front and rear sights and internal parts, and the smooth-angled, snag-free low-profile rear sight allows for a quick draw. A skeletonized hammer, beavertail grip safety, and conventional safety lock pair with double-diamond checkered wood grips and a crisp factory 4-to-6-pound trigger pull. Among compact semi-auto handguns, this Rock Standard ECS configuration favors shooters who want a compact stainless 1911 for carry.
