Springfield 1911-A1 Mil-Spec 45ACP Stainless Steel

When you need a factory-fresh 1911 that honors the original military design while delivering modern reliability, the Springfield 1911-A1 Mil-Spec 45ACP Stainless Steel stands as the definitive choice. Built on Springfield Armory’s proven platform, this pistol combines forged carbon steel and stainless steel components with a parkerized and bead-blasted finish that resists corrosion. Chambered in .45 ACP with a 5-inch barrel, it offers the exact balance of weight, trigger pull, and sight picture that defined the sidearm of the U.S. Armed Forces. Whether you are a collector, a competitive shooter, or a concealed carrier who values traditional ergonomics, this firearm delivers consistent performance at a price point that respects your budget.

Overview

Springfield Armory’s 1911-A1 Mil-Spec is a direct descendant of the pistol that served through two world wars. The stainless steel variant offers enhanced durability without sacrificing the original dimensions, including a standard government-length slide, a military-style spur hammer, and a flat mainspring housing. Every component is machined to mil-spec tolerances, meaning you get the same lockup, trigger reset, and magazine release as the original 1911A1. The satin stainless finish reduces glare and simplifies maintenance, making this .45 ACP pistol suitable for both range use and daily carry.

• Caliber: .45 ACP with a 5-inch forged stainless steel barrel and 1:16 twist rate
• Overall length: 8.6 inches, height: 5.5 inches, empty weight: 35 ounces
• Magazine capacity: 7+1 rounds, includes two 7-round stainless steel magazines

Features & Specs

Every aspect of the Springfield 1911-A1 Mil-Spec 45ACP Stainless Steel is built for function. The frame and slide are forged from 4140 steel and then bead-blasted for a non-glare finish. The mil-spec barrel features a standard bushing and a lowered, flared ejection port for reliable extraction. The trigger is a standard long, curved military trigger with a crisp break, while the sights are a standard GI-style front blade and rear notch, drift-adjustable for windage. All internal parts are machined to interchange with original USGI 1911A1 components.

• Forged carbon steel frame and slide with satin stainless finish
• Standard mil-spec grip safety, thumb safety, and hammer
• 7-round magazine with flat base pad; magazine release is standard GI length

• Trigger pull weight: 5–6 pounds, factory-certified
• Overall width: 1.25 inches at the safety, 1.0 inch at the slide
• Includes OEM lockable case, cable lock, and owner’s manual

Who It’s For

This pistol is designed for shooters who demand the original 1911A1 configuration without modern modifications. It fits the collector who wants a faithful reproduction of a WWII-era sidearm, the practical pistol competitor who prefers traditional iron sights and a 7-round magazine, and the civilian defender who trusts the .45 ACP cartridge and the 1911 platform for home defense. Because it is built to mil-spec standards, it is also an excellent base for custom work if you later choose to upgrade grips, sights, or internals. However, if you require a rail, an ambidextrous safety, or an extended beavertail, this model is not for you.
