Overview

The Springfield 1911-A1 45 ACP Professional Light Custom Shop Pistol represents a refined evolution of the classic 1911 platform, engineered by Springfield Armory’s Custom Shop for discerning shooters who demand precision, reliability, and reduced weight. Built on a forged carbon steel frame and slide, this pistol incorporates a lightweight aluminum trigger and an ambidextrous thumb safety, delivering a balanced handling profile without sacrificing the structural integrity expected from a duty-grade firearm. Each unit is hand-assembled and inspected by Custom Shop armorers, ensuring tolerances that exceed standard production models.

Features & Specs

This Custom Shop pistol is designed for shooters who prioritize low-mass operation and rapid target reacquisition. The lightweight slide configuration, combined with a flat-wire recoil spring system, reduces felt recoil and muzzle rise while maintaining reliable cycling under adverse conditions. The frame incorporates an integral accessory rail for mounting lights or lasers, and the slide is fitted with low-profile Novak tritium night sights for low-light engagement. Below are the core specifications:

• Caliber: .45 ACP; Barrel Length: 5 inches (forged stainless steel, match-grade with fully supported ramp); overall length: 8.6 inches; weight: 36.5 ounces (unloaded)
• Frame: Forged carbon steel with black Armory Kote finish; slide: forged carbon steel with matching Armory Kote; includes integral 1913 Picatinny rail
• Sights: Novak LoMount tritium front and rear; trigger: lightweight aluminum, 4.5-5.0 lb pull; safety: ambidextrous thumb safety and grip safety

Additional Custom Shop features include a lowered and flared ejection port, a polished feed ramp, and a one-piece stainless steel guide rod. The pistol ships with two 7-round magazines and a Custom Shop hard case. The springfield 1911-a1 45 acp professional light custom shop pistol is hand-fitted to ensure slide-to-frame fit, barrel lockup, and trigger break consistency—attributes that distinguish it from off-the-shelf 1911s.

Who It’s For

The Springfield 1911-A1 45 ACP Professional Light Custom Shop Pistol is intended for experienced shooters who require a lightweight, full-size 1911 for concealed carry under structured clothing, competition use in limited divisions, or as a defensive sidearm where weight reduction matters without compromising capacity or caliber. The Custom Shop’s focus on reliability and accuracy makes this pistol suitable for law enforcement officers, competitive shooters, and discerning collectors who demand factory-level customization. It is not recommended for novice shooters due to the single-action trigger system and manual safety; proficiency with the 1911 platform is assumed. The lightweight frame and reduced slide mass are specifically designed for users who carry for extended periods or engage in high-volume training sessions.
