If you mean 'snubby grips'...
Since my snub is a 3" Taurus 85 stainless .38, it doesn't really qualify as a J-frame exactly, but mine wears Pachmayr Compac rubber grips.
The place I bought them from let me try everything they had in stock for it (without firing the gun). I tried Uncle Mikes, Pachmayr, Eagle, and one other make I can't remember the name of right now. Different styles, composition, etc. The Pachy Compac rubber just felt 'right' to me at the time. I've never felt it was a bad choice.
