I recognized the quality of the piece. The dimensions were perfect, aligning with holes, front and back, and sides. The enclosed screws fit perfectly. And the plate not only matched the firearm, but also the optic without any need for modification or adjustments. Installation videos are available and they were comprehensive. I also contacted C&H with some questions and they were very good to offer technical advice and help. I am very pleased with this product, glad I decided to get it, and I do recommend it. Review: Excellent fit...don't go cheap for an RMR - Excellent fit for my CA320 (California Legal P320 M18 made by Franklin Armory). No gap and the needed screws came with the plate. This was for a Trijicon type 2 RMR. Looks great! If you are thinking about a cheaper plate, don't do it. I bought 3 different plates. This one is higher priced but you get higher quality, feels more durable, same thickness, and a more confident fit. ## Features - COMPATIBILITY: ONLY compatible with SIG P320 RX Series, Pro series, and AXG Scorpion models with Romeo 1 Pro Optic Ready DPP Cut with RMR holes.
