    The M1911A1-FS follows the Government-pattern format with a 5" barrel and full-size steel frame and slide. It wears a matte dark gray/black finish with the Rock Island Armory crest on the slide, and carries import markings "APINTL-PAHRUMP NV" and "ACP PHILIPPINES." Sights are GI-pattern with a staked small front blade and a low-profile rear notch in a dovetail.

    Controls and operation are true to the platform: single-action, short-recoil, locked-breech system with a manual thumb safety and grip safety. It has a standard magazine release, a short, solid 1911-style trigger, and a spur hammer.

    The slide features rear-only vertical serrations and a standard ejection port. It uses a standard barrel bushing and a checkered recoil spring plug. The front strap is smooth, and the arched mainspring housing has vertical serrations.

    Furniture consists of smooth hardwood grip panels. Capacity is 8+1, supported by the included single-stack steel magazine with numbered witness holes (2-8). The barrel hood is marked "CAL .45 ACP."
