I have a 657 no dash that I bought used some time ago. The previous owner had rubber grips on it, a trend I have never understood and cannot tolerate. I bought a set of new Smith & Wesson square butt target grips to replace the ugly Hogues. However, when I removed the used tire grips, I was surprised to find a round butt grip frame. I didn't know that there were any 6" 657's from the mid 80's that sported a round butt grip. I guess I'll have to continue my search for the round to square conversion grips that Smith markets.
