Now do the other side , use just a little putty in the loose spot(s) , put both sides together and tighten screw, Now...remove the screw and double check that the epoxy is not oozing out and cementing both grips to each other....if all is ok, replace grip and screw and let cure. Don't wiggle the grips until the epoxy cures . Wax the metal ...putty will not stick to a waxed surface ( usually).
I've fixed many an ill fitting grip this way. Putty is easier to keep from flowing into places you don't want it.
If the grips still move on you , you just repeat the above, usually the first time does it but you might need to fine tune the fit with another treatment .
