The Rock Island Armory 1911 series is a product line of single-action recoil operated semi-automatic pistols. They are designed and manufactured by Armscor in Marikina, Philippines,[1] and distributed in the United States by Armscor USA, located in Pahrump, Nevada.

RIA (Rock Island Armory) 1911s are clones of the US Military G.I. M1911-A1, the standard issue US Service pistol from 1911 to 1985.[2] Most RIA models are targeted for the low-end price point of the 1911 pistol market and are basic entry level MIL-SPEC versions of the 1911,[3] however, the RIA Tactical,[4] Compact, and Match models offer additional semi-custom high end features. The Compact model features a skeletonized hammer and beavertail grip safety while the Tactical model also adds a target-grade hammer and trigger as well as an ambidextrous safety, and enhanced contrast combat sights. Armscor is an ISO 9001 certified-compliant company which manufactures Rock Island pistols using CNC (Computer Numerical Control) equipment.[5] RIA 1911 series pistols are constructed of 4140 chromoly steel with a cast frame, and are available in .45 ACP, .38 Super, 9mm Luger, and .22 TCM chamberings.[6][7]
