The Auto-Ordnance 1911A1 series incorporates GI specs, and features a matte black finished frame, barrel, and slide. The carbon steel slide, sear, and disconnector are machined from solid bar stock, then heat treated properly for durability over many thousands of rounds. Models are available in .45 ACP, and 9mm. Barrel lengths are offered in the original 5”, and the Commander length 4.25”. The low-profile sights feature a blade front sight and a rear drift adjustable for windage.
