I just rounded the msh on my new kimber ultra carry ,it took about a minute to do on my disk/belt sander and a little touch up by hand. very easy job looks close to Tim Brian one ie:not as rounded as the Tussey. It helped alot as the msh was diging into my palm.
Here's a better picture of the round-butt gun and another CCO with a butt that is original. The rounded gun feels sooo much better in your hand. As far as anodizing goes, if you are limiting your metal work to that bottom rear corner, I see no reason to get in too big a rush to re-anodize it. Carry it until it needs refinishing from fair wear & tear. In the meanwhile (if it's a black gun) fog a little barbeque grille paint on it, in that corner.
