oldhenry, I had a pair of N frame target grips from the 1960's that were in rough shape when I got them on a used S&W 1937 .45acp. I decided since they were in bad shape anyway to try and see what I could do to make them fit my hand. I stripped them, and then started slowly removing a little wood at a time until I got the fit that I wanted. Worked out great for me. I finished them with by first filling the grain and then a rubbed oil finish and I now have a set of N frame grips that fit me like a glove. If you can find an old trashed set of the Target grips, you might want to try doing the same. It is not very hard if you take your time and work slowly. james
