The Springfield Armory 1911 Ronin AOS 5" 9mm Gear Pac fuses retro two-tone styling with modern high-capacity range utility and advanced optical precision straight out of the box. Configured in a full-size Government profile, this handgun features an ultra-robust architecture constructed from a premium forged stainless steel frame and a contrasting, deep hot-salt blued forged carbon steel slide. Beneath its masterfully machined exterior surfaces sits a 5-inch match-grade forged stainless steel barrel and a traditional recoil spring bushing assembly to maintain premier mechanical accuracy. The focal point of the PX9119LAOS-PAC bundle is the cutting-edge Agency Optic System (AOS) developed alongside Agency Arms. This slide-milled interface uses specific machined plates to direct-mount the included Viridian® RFX11 green dot optic incredibly low, promoting an intuitive sight picture and seamless co-witness capabilities. Shipping entirely field-ready inside a heavy-duty nylon zippered pistol bag, this comprehensive factory configuration packs an expanded firepower payload of four 9-round factory steel magazines.
