Features & Specs

Built to the exact tolerances of the original 1911A1 design, the springfield 1911-a1 mil-spec 45acp stainless steel delivers consistent performance with .45 ACP ammunition. The barrel length, frame dimensions, and grip safety profile all match the government-issue specifications that have proven reliable for over a century.

• Caliber: .45 ACP with a 5-inch stainless steel barrel, 1:16 twist rate, and a feed ramp polished for reliable cycling with hardball and hollow point ammunition
• Frame and slide constructed from 416 stainless steel with a brushed satin finish, providing resistance to rust and corrosion while maintaining the parkerized appearance of the original military finish
• Seven-round magazine with steel body and polymer basepad, plus a second magazine included; both magazines feature a flat follower for proper slide lock on empty

The trigger system uses a standard mil-spec single-action design with a three-hole aluminum trigger, offering a consistent 5- to 6-pound pull weight. Sights are the original military-style dovetailed front blade and rear drift-adjustable notch, designed for quick acquisition and reliable point-of-impact at 25 yards. The thumb safety and grip safety are both functional and ambidextrous, with the grip safety featuring the original raised pad.

• Overall length: 8.6 inches; height: 5.5 inches; width: 1.25 inches; weight unloaded: 35 ounces (approximate)
• Slide features forward and rear cocking serrations, a lowered and flared ejection port for reliable extraction, and a loaded chamber indicator

Who It’s For

This springfield 1911-a1 mil-spec 45acp stainless steel is designed for shooters who prioritize mechanical reliability and historical accuracy over modern ergonomic modifications. It is well-suited for competitive shooters in Single Stack or Limited divisions, as the mil-spec dimensions allow for direct compatibility with holsters, magazine pouches, and spare parts from the aftermarket. Law enforcement personnel and armed citizens in Illinois who prefer a traditional hammer-fired single-action platform will appreciate the consistent trigger reset and manual safety engagement. Collectors seeking a stainless steel variant of the original 1911A1 pattern will find this model retains the parkerized-style finish while offering the practical benefit of corrosion resistance. It is also appropriate for shooters who intend to customize their firearm, as the mil-spec frame and slide accept most commercially available grips, triggers, sights, and internal parts without modification.

• Suitable for range shooting, defensive carry, and historical collection; not recommended for concealed carry without a proper holster due to full-size frame dimensions
• Operates with standard pressure .45 ACP ammunition; avoid +P or +P+ loads to preserve service life of the barrel and recoil spring
• Break-in period of 200 to 500 rounds recommended for optimal function; stainless steel surfaces may require light lubrication during initial use
