Finished in Coyote Brown Cerakote, the bobbed portion of the frame reduces potential printing while maintaining a comfortable grip. Typically reserved for custom firearms, the TRP features 20 line-per-inch (LPI) checkering for a firm grip as well as top slide serrations for reduced glare and faster sight alignment. Now enhanced with the Agency Optic System (AOS), the TRP supports a wide range of popular optics, including RMR, Shield, Delta Point Pro, and Docter. Each AOS plate integrates a black serrated rear sight that ensures optimal optic height and an intuitive sight picture, enabling visible co-witnessing in nearly all configurations.
