The C & H Precision Kimber KDS9C Steel Plate is a heavy-duty, professional-grade mounting adapter engineered specifically to attach the Holosun 509T enclosed-emitter optic onto the optics-ready Kimber KDS9c pistol. Precision CNC-machined from solid steel and protected by a durable corrosion-resistant finish, this rugged plate replaces factory multi-optic kits with a much tighter, movement-free interface designed to withstand harsh defensive and competition recoil. A standout feature is the integrated rear sight built directly into the back of the plate, ensuring shooters maintain a reliable backup iron sight picture after the factory rear sight cover plate is removed. Its ultra-low-profile architecture minimizes the optic's height over bore to guarantee a fast, intuitive point of aim during rapid target transitions. Proudly made in the USA, this duty-rated plate delivers maximum structural integrity to prevent screw failure and preserve an unyielding, repeatable zero.
