Description
The Auto-Ordnance 1911A1 GI Spec .45 ACP 5-inch 7-round is a faithful reproduction of the classic sidearm that served our fighting men through two world wars, built right here in the U.S.A. with a matte black carbon-steel frame and slide, checkered wood grips with an integrated U.S. logo, and a beavertail grip safety. It comes as a Series 80 model with a firing pin block, low-profile sights, and one 7-round magazine, ready for the range or the field.

Key Features
- GI-Spec Dimensions: This pistol mirrors the original 1911A1 military specs with a 5-inch barrel and 7-round magazine, so you get that same point-and-shoot feel that’s won countless matches and battles.
- Checkered Wood Grips with U.S. Logo: The walnut grips are checkered for a secure hold and feature an embedded U.S. logo—a nod to tradition that also gives you a non-slip purchase even with sweaty hands.
- Series 80 Firing Pin Block: A drop-safety mechanism that blocks the firing pin unless the trigger is pulled, giving you peace of mind when carrying or storing the pistol.
- Low-Profile Sights: The front blade and rear notch are dovetailed and set low to the slide, which keeps them snag-free and authentic to the original design while still being usable for accurate shot placement.
- Beavertail Grip Safety: The extended beavertail prevents hammer bite and ensures a high, comfortable grip that helps you manage the .45 ACP recoil shot after shot.
Who It’s For
This Auto-Ordnance 1911 is for the traditionalist who appreciates the history and handling of John Browning’s original design. It suits the bird hunter who wants a reliable sidearm for the field, the collector building a World War II-themed safe, and the shooter who prefers a no-frills, all-steel .45 that just works.
Pros and Cons
- Pros: Authentic GI feel; all-steel construction soaks up recoil; Series 80 safety adds drop protection; price point under $800 makes it accessible.
- Cons: The low-profile sights are small for modern eyes—some folks prefer a three-dot upgrade. Also, the trigger pull is a bit heavy out of the box, typically around 6–7 pounds, which is true to the original but not as crisp as a tuned 1911.

FAQ
What does “GI Spec” mean for this pistol?
It means the dimensions, finish, and parts are made to the same standards as the original 1911A1 issued to the U.S. military. You get a 5-inch barrel, 7-round magazine, matte finish, and the same grip angle and trigger pull weight as the wartime guns.
Is the Auto-Ordnance 1911A1 GI Spec compatible with aftermarket 1911 parts?
Yes, it accepts standard 1911 parts including triggers, hammers, grips, and magazines. Because it’s a Series 80 model, be sure any replacement firing pin or safety parts are specifically for Series 80 pistols.
How many magazines come with it?
One 7-round magazine is included in the box. Extra magazines are widely available and affordable.
What is the finish like?
It’s a matte black oxide-type finish on carbon steel that’s durable and non-reflective, just like the original military parkerization but in black.
