The optic ready S2 from CZ uses sight specific plates for mounting red dots. Also the slide is contoured differently ( wider at the top ) at the rear than standard. Check to see if they make a plate for your sight. The slide is milled long for the plate, but the plate itself is cut for a snug fit to the optic. I actually bought two plates for the S2 optic ready, one for a Leupold DPP and one for a Burris fastfire. Don’t even have a S2 yet! Maybe a direct to slide cut would work better for you if possible on the S2 ?
