Rock Island Armory M1911A1 Rock Standard FS in .45 ACP with a 5″ button-rifled barrel, parkerized steel frame and slide, full-length guide rod, ambidextrous safety, and an 8-round magazine.

The Rock Island Armory M1911A1 Rock Standard FS (MFG #51431) is a full-size, steel-frame 1911 chambered in .45 ACP with a 5″ button-rifled barrel and a parkerized finish. The design follows the 70-series 1911 pattern and includes a full-length guide rod, skeletonized hammer and trigger, and an ambidextrous safety for modern handling. Its factory trigger is specified in the 4–6 lb range, and it ships with an 8-round magazine and a plastic case.

For an optic that pairs well with this platform and stays under $1,000, a compact pistol red dot such as the Trijicon RMR or a comparable micro reflex sight is a suitable choice for sight acquisition without significantly altering holster options.
