Springfield Armory 1911 Operator AOS | .45 ACP | 5.75″

The Springfield Armory 1911 Operator AOS is a full-size, optics-ready 1911 chambered in .45 ACP with a 5.75″ threaded barrel. It combines forged steel construction, G10 grips, and a match-grade barrel profile to serve shooters who value traditional 1911 ergonomics with modern optic compatibility. For an optic under $1,000 that pairs well with the AOS cut, consider a Trijicon RMR Type 2 for a durable, low-profile red dot that co-witnesses effectively with the integrated rear sight plate.

Recommended uses include precision-focused range training and competition where a steel-frame 1911 benefits from a tuned trigger and optics-ready slide.
