Springfield Armory 1911 Ronin AOS Pistol, 9mm, 5-Inch, Blued/Stainless

The Springfield Armory 1911 Ronin AOS pistol in 9mm with a full 5-inch barrel and blued/stainless finish (brand part no. PX9119LAOS) combines a legacy of service with modern optics compatibility through Springfield’s Adaptive Optics System. Springfield Armory forges the carbon steel slide and stainless steel frame separately for lasting durability, and the 5-inch hammer-forged barrel uses a traditional recoil spring assembly and barrel bushing. AOS mounting plates fit a wide range of popular optics including RMR, Shield, Delta Point Pro, and Docter, each with an integral rear sight for proper co-witnessing. Crossed cannon wood laminate grips and a GI-style recoil system complete the build. Among full-size optics-ready semi-auto handguns, this Ronin AOS configuration favors 1911 shooters who want a traditional 5-inch platform with modern red dot compatibility.
