Auto-Ordnance 1911
The Auto-Ordnance 1911 is a family of Government-model 1911A1 pistols built to the original WWII military specifications, available in Parkerized, blued, stainless, and special edition finishes in .45 ACP and 9mm. Auto-Ordnance produced 1911A1 pistols for the U.S. military during World War II under government contract, and the current production lineup traces directly to that heritage — the same 5-inch barrel, GI sights, lanyard loop mainspring housing, and short trigger that defined the wartime pistol.

Full Auto-Ordnance 1911 Lineup
1911A1 WWII Parkerized (.45 ACP): The most historically accurate Auto-Ordnance 1911, finished in Parkerized matte gray to match the original wartime contract pistols. Features GI-style fixed sights, checkered plastic grip panels, 5-inch barrel, 7+1 capacity, and the original short trigger and flat mainspring housing. The closest production equivalent to an actual WWII-contract 1911A1.
1911A1 Blued (.45 ACP): The classic commercial configuration with a polished blue finish, checkered walnut grip panels, and standard GI specifications. A step up in aesthetics from the Parkerized model while maintaining identical mechanical configuration.
1911A1 Stainless (.45 ACP): The stainless steel variant offers corrosion resistance without sacrificing the original 1911A1 geometry. Ideal for humid climates, maritime use, or buyers who prefer stainless for long-term storage.
1911A1 9mm Government: The 9mm Government model brings the original 5-inch Government frame to the most popular carry caliber. Higher capacity than the .45 ACP model with lighter recoil, making it accessible for new 1911 shooters while retaining the classic GI profile.
Squadron 1911 and Special Editions: Auto-Ordnance produces limited WWII-themed special editions honoring specific military units and campaigns, with appropriate rollmarks, finishes, and packaging. These are both shootable firearms and collector pieces.

Auto-Ordnance 1911 vs Rock Island 1911: GI-Spec Compared
The Auto-Ordnance 1911A1 and Rock Island Armory GI models are the two most prominent GI-specification 1911s at the accessible end of the market. Rock Island offers broader model variety and slightly lower entry points on base models; Auto-Ordnance brings the historical authenticity of an actual WWII contract manufacturer and the Parkerized finish correct to wartime pistols. For buyers who specifically want a 1911 with WWII provenance behind the brand name, Auto-Ordnance is the only production option.
Why GI-Spec Still Makes Sense
The GI-specification 1911A1 — fixed sights, short trigger, flat mainspring housing, no beavertail — is the configuration John Browning designed and the U.S. military issued for over 70 years. For buyers who want a traditional 1911 without modern modifications, the GI spec provides a lighter trigger guard clearance for small hands, a flatter profile for carry, and lower overall weight than 1911s with extended beavertails and tall sights. Many competitive 1911 shooters train on GI-spec pistols specifically for the challenge. The Auto-Ordnance 1911A1 delivers all of this at a competitive price point.
