Hi Bud.
I've tried well over a dozen different grips on various J-Frames and always come back to these Uncle Mikes, as shown on a 360PD.
A tad longer than some prefer, but with the right holster cant, they work very well for me.
Discontinued, but can often be found on e-Bay. Similiar, if not identical grips can be found on the Smith & Wesson Mfg. site, as well.
