The Springfield Armory 1911 Ronin AOS 5" .45 ACP Gear Pac flawlessly fuses classic two-tone tactical elegance with modern high-capacity value and advanced optical precision straight out of the box. Configured in a full-size Government profile, this handgun features an ultra-robust footprint 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 elite downrange consistency. The signature feature of the PX9120LAOS-PAC package is the integration of the Agency Optic System (AOS) developed in partnership with Agency Arms. This slide-milled interface uses specific machined adapter plates to mount the included Viridian® RFX11 green dot optic incredibly low, promoting an intuitive sight picture and co-witnessing capability with the iron sights. Shipping entirely field-ready inside a heavy-duty nylon zippered range bag, this comprehensive factory configuration packs an expanded firepower payload of four 8-round factory steel magazines.
