I am just wanting to make sure, before I order some grips for this gun. Mine still has the original S&W rubber grips, and I would likke something better. I looked this gun up in the S&W catalog and it says this gun is built on the N-frame. And the grips for it would be the N frame round butt, is this right. I appreciate any advice and any recomendations on a set of grips. I have alot to learn about these guns....Thanks.....Ray
