The 1911 Operator features a forged frame and slide paired with a match-grade barrel for the perfect combination of toughness and performance demanded of a no-nonsense duty and defensive pistol. Tactical rack sights allow for easy one-handed manipulation while the front sight uses a tritium insert for visibility in low light environments. The frame also features an accessory rail for attaching lights and lasers along with ambidextrous safety levers for left-handed or off-hand shooting. The AOS series upgrades the pistol with Springfield's Agency Optic System (AOS). Developed in collaboration with Agency Arms, the AOS employs a series of adapter plates to allow for easy fitment of a wide variety of today's most popular optics. AOS adapter plates are machined from billet steel for durability and precise fitment. The plates also feature integrated rear sights for easy co-witness with the chosen optic. This model is chambered in .45 ACP and features a 5.75-inch threaded barrel and a FDE Cerakote finish. Two 8-round magazines are included along with Springfield's soft double-zipper case.
