Key Features
- GI-Spec Dimensions & Profile: The Auto-Ordnance 1911A1 matches the original military blueprint—short trigger, arched mainspring housing, and lanyard loop. Why it matters: You get the same ergonomics and handling as the sidearm carried by generations of American servicemen, with no modern compromises.
