Those really look good. The "thin-ness" of the grips don't seem to be a factor for me when shooting 357. So far i've shot over 400 rounds of straight 357 & its eating them up like crazy. Love the 627-5 PC & could shoot it all day. The pair of these grips on my 686-4 snubby also makes 357 not bad either. Best of luck.
