The grips I bought are countersunk but are thicker than they could be. They are not the very nice Marschal grips but a set I got off EBay. Even though they were from Bangkok,Thailand they are made from one solid piece and are Padauk wood. They could be reworked and thinned down some later maybe when I get some time. I will call Bersa and get the longer screws for now. Thanks for the info on the screws.
