Bought a beavertail to put on my RIA. Not sure of the maker as it was a spare takeoff part. Looks unused, but it's not gonna fit now that I have it. The inner tang on the GS that I purchased turned out to be flush with the side of the GS rather than offset inside by 1/16". With it flush to the side, it is hitting part of the trigger slot on the frame and not allowing it to fit in all the way. I know I can't alter the GS to get that offset, but can I buff down about an 1/8th inch of that slot and still have the GS function? Don't want to do it if it could cause other issues. I may have to just order another GS, but wanted to ask the experts here first.
