The Kimber Compact I just got last week has a nasty sharp edge on the corner of the grip where the mainspring pin is. This sharp edge just happens to stab directly into my strong side love handle. My New Agent has a rounded corner, and I can carry it all day and not know it's there. The Kimber's checkered mainspring housing doesn't feel very nice against the side either, but that is easily fixed by buying a new one.
My question is, is there an approved DIY way to do this. In the past, I have re-blued a grip safety after fitting, refinished 5 handguns with Moly Resin, and done a good bit of part fitting. Would it be as simple as using a stone to round the edge, then a touch-up refinish?
