The Emissary AOS in .45 ACP features an all-black Cerakote finish and custom 1911-style enhancements for a serious defensive pistol. Its 5 barrel is paired with a Tri-Top cut slide with 40 LPI flat-top serrations and a heavy-profile bull barrel for maximum accuracy and reduced muzzle flip. With a forged slide and frame for strength and durability the Emissary seamlessly blends form and function. The pistol also includes the Agency Optics System (AOS) with plates compatible with popular footprints like RMR Shield Delta Point Pro and Docter. Each AOS plate has an integral rear sight for proper optic height and an intuitive sight picture providing a visible co-witness in nearly all configurations. - Caliber .45 ACP - Color Black - Barrel 5 Forged Stainless Steel Nitride Match Grade Bull 1:16 - Slide Forged Carbon Steel Black Cerakote Optics-Ready - Frame Forged Stainless Steel Black Cerakote - Sights Tritium/Luminescent Front Black Serrated Rear - Recoil System One Piece Full Length Guide Rod - Grips VZ Grips Thin-Line G10 - Magazines (2) 8-Round - Weight 43 oz - Length 8.4 - Height 5.25
