Looks and feel. They just really look balanced on a short bbl gun (4" or less) and it feels better too. Probably the part that feels better about it is that I always thin the grips to almost the thickness of where the screw goes through and round the bottom edges also. This takes most of the flare out of them and you don't have the corners on the bottom to deal with under recoil. I also prefer to use an aluminum grip frame for this procedure as it also lightens up a compact gun. I had a SBH where the stock steel grip frame was roundbutted and the grips thinned and it improved the grip a lot (Of course, I have small hands, someone with large hands may feel different). Of course the best grip for heavy recoil is the Ruger bisley style, BUT I liked the rounded SBH grip better. The barrel was cut to 5" and I've never handled a better balanced gun. 44 Man
