What are we talking here? About 1/4 inch of steel at the heel of the butt? I don't know about all of you, but on my 200+ lb. body, and the clothes I wear over my CCW, a little extra steel on the heel isn't going to get noticed by anyone. They are either going to see my gun "print" in general, or, probably, not at all. I would go with whatever you like, aesthetically, or if it truly gives you a better feel, or point shoots better, but that might mean shooting both styles to some extent before you know. I find I can shoot with either style in a K-frame, but have come to prefer the square with a grip adapter or boot style grips.
