Please confirm your PDP version before buying the plate, v1 and v2 plates are not interchangeable.
From October of 2023, we've begun to transition T10 sight to plate screws to T15.
Trijicon's new RCR and RMR HD are both compatible with OPF-PDP, RMR. If you have an RCR, you must use the capstan screws that came with the RCR.
V2 PDP slides have a longer optics cut, the serial numbers start with FDL9203, FDM0001, FDN3124). V1 PDP optics cut is 1.85" at the longest, while v2 cut is 1.93 at the longest. Please be sure to check your serial number and/or measure the optics cut before choosing the correct plate.
The above V2 serial numbers made available by Walther are almost a year old, now please remove the cover plate and verify the version.
