Featuring an unyielding commitment to strength, reliability and quality, the Ronin 1911 combines a legacy of service with the features modern shooters demand. Strength is a core element of the Ronin line, with all models featuring forged steel slides, hammer-forged barrels, and forged frames. The steel slide features a beautiful hot salt bluing finish that contrasts nicely against the forged stainless steel frame of the 5" model and the forged alloy frame of the 4.25" and EMP model, the latter of which features a satin aluminum Cerakote finish. Designed and built for a lifetime of service, the Ronin family of pistols offers 1911 enthusiasts a highly refined handgun with unparalleled durability and strength. Now, Springfield Armory has taken the precision and shootability of the 1911 and added modern optics integration direct from the factory. Developed in collaboration with Agency Arms, the Agency Optic System (AOS) employs a series of plates fitting a wide variety of today's most popular optics following the RMR, Shield, Delta Point Pro, and Docter footprints.
