Well, I just put a Viridian RFX45 (RMR to ACRO footprint) on my M&P 40 S&W 1.0 PC C.O.R.E. and love it!
My mounting plates are metal (as should be yours) and those basic footprints really haven't changed... There's nothing hard about mounting a red dot: just follow the brand's suggestions re: cleaning and torque values.
Cheers!
P.S. A Vortex Viper (Doctor/Burris footprint) is pretty hard to beat and there is one on $ale for under $125 at Optics Planet right now: the Vortex Warranty is really one of the best!
Cheers!
