The Emissary 4.25” AOS in 9mm features a Cerakote® finish and custom 1911-style enhancements, offering a serious defensive pistol.

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.
