The Springfield Armory 1911 Operator 5" AOS .45 ACP Tungsten pairs full-size duty authority and classic single-action performance with modern low-profile optical adaptation. Configured as a standard Government model, this firearm utilizes an incredibly strong forged carbon steel frame and slide coated in a protective, matte Tungsten Gray Cerakote® finish to combat environmental abrasion and hard holster wear. Nestled inside its robust frame is a 5-inch match-grade forged stainless steel barrel optimized for exceptional downrange mechanical precision. The structural highlight of the PO9230TAOS configuration is the advanced Agency Optic System (AOS) developed in partnership with Agency Arms. This slide-milled footprint utilizes pin-keyed machined steel adapter plates that house an integrated rear iron sight, seating your favored micro red dot deep within the steel to lower height-over-bore metrics and ensure a completely natural co-witness. Complete with an integrated dustcover Picatinny rail, forward slide serrations, texture-matched VZ Grips® G10 panels, and an ambidextrous safety, it ships completely duty-ready from the factory with two 8-round bumper-padded steel magazines.
