Each plate is precision-machined in the USA from 6061 aluminum and finished with a MIL-SPEC Type III Hard Anodizing. This high-performance mount is engineered to provide a precise fit across the Walther PDP 1.0 platform, ensuring reliability for all calibers, including 9mm and .40 S&W. To guarantee a secure, long-lasting zero even under heavy recoil, this plate utilizes a patented 416 Stainless Steel T-Nut system that provides an industry-leading six to seven threads of engagement. Included: The T-nuts (provided) fit into small pockets under the plate before the plate is seated in the optic cut on the slide. Then install the plate mounting screws (provided) and torque to 11-in lbs. Finally, install the ROMEO1PRO and use the 4-40 screws (provided) and torque to 11-in lbs.
