The Springfield Armory 1911 Emissary AOS Pistol features a Cerakote finish and custom 1911-style enhancements, offering a serious defensive pistol. Its "Tri-Top" cut slide with 40 LPI serrations houses a heavy-profile bull barrel for accuracy and reduced muzzle flip. The forged slide and frame include a Picatinny rail, merging form and function. The Agency Optics System (AOS) adds versatility, fitting popular footprints like RMR, Shield, Delta Point Pro, and Docter. Each AOS plate has an integral rear sight for proper optic height and a visible co-witness in nearly all configurations, enhancing precision and defensive capability.FeaturesTri-Top SlideOptics ReadyTritium Front SightMatch Grade Bull BarrelNote: AOS optics plates will need to be purchased separately.
