No, the RS-Pro uses the Deltapoint Pro footprint. You would need the Romeo-RS Compact model which can be found linked below:

will this fit a Glock 43X MOS

Yes. It fits onto any GLOCK slide as long as there is a RMR cut. If not, on this site a few guys sell underplates to mount onto the rear sight cuts. then go for it.
