Springfield Armory has introduced an upgraded version of its single-stack 1911 Operator chambered in .45 ACP, adding modern tactical features while maintaining the platform’s traditional design. The new 1911 Operator AOS Threaded models feature suppressor-ready threaded barrels, the AOS optics-mounting system and corrosion-resistant Cerakote finishes.

At the core is a forged carbon steel frame and slide, paired with a 5¾-inch stainless steel barrel featuring .578x28 threading for attaching muzzle devices. Plus, a knurled thread protector comes standard.

These new pistols also feature the AOS (Agency Optic System) developed in collaboration with Agency Arms, which supports multiple red-dot sight footprints via modular steel plates—including Trijicon RMR, Leupold DPP, Shield and Docter-style optics. Buyers get a cover plate, which includes a rear sight, and can order one optic plate at a discounted rate of $49.

Additionally, each 1911 Operator AOS Threaded .45 pistol includes G10 grips, an accessory rail, tritium front sight, ambidextrous safety and two eight-round extended base pad magazines.

This update positions Springfield Armory’s 1911 Operator AOS Threaded pistols as a bridge between classic designs and modern handgun expectations.
