Depending on what receiver you're using, and how the production of your SD grip was, you may also have to modify the area where the beavertail sits, as well as the tops of all external edges and all internal features that contact the bottom of the receiver. It's not so cut and dry to identify the specific areas. There were certain runs of the grips that required ZERO modification at all, but I suppose the dies used for moulding the grips began to wear down with time and is causing these tolerance issues.
