The GI Standard configuration delivers a traditional 1911 layout with single-action, short-recoil operation and a Series 70-type firing system without a firing-pin block. Controls include a left-side thumb safety and a grip safety, and the hammer is the classic spur type.
The slide and frame are steel with a uniform matte Parkerized finish. The slide has rear-only vertical serrations. Black checkered synthetic grip panels with Rock Island Armory medallions provide a secure, GI-style feel.
GI-pattern fixed sights consist of a staked front blade and a square-notch rear. This straightforward sight setup supports the model’s GI theme.
Markings include the Rock Island Armory crest/logo on the right side of the slide and a model roll mark "M1911 A1 – FS" on the frame. Import and proof markings read "APINTL – PAHRUMP NV" and "ACP PHILIPPINES." The factory inspection/assembly card is dated April 22, 2022.
