I ordered this for my Walther PDP 9mm... They said they is for the 1.0 not the new style 2.0. It was ordered for the following optics:

TRIJICON RMR, SRO & HOLOSUN 407C, 507C & 508T and the Riton X3 PRD

After getting the plate, i ended up getting a  LEUPOLD DELTA POINT PRO from a friend which requires a different plate so i do not need this one. It is brand new and never mounted. I got it from Optics Planet for $103.99. See pics and make sure it looks right for your pistol. I added a screenshot from walthers page to determine if yours is a 1.0 or 2.0.

You can order these through Optics Planet but, as mentioned, they are early $104.00 and they are back ordered with an unknown ETA. Some other places are $69.99-$99.99 but they are back ordered as well. Selling for $60.00 in Topeka.
