Here's a few:
Model 60 with the old "Lightning" grips by Bianchi. Kinda heavy, but makes the 36s and 60s snag-free. I use this one in a shoulder holster when appropriate.
This 642 has a set of Hip-Grips, made by Barami. They enable very useful pocket carry.
This 649 also has Barami Hip-Grips, seen from the other side.
Here's a 640 with a set of Herrett's "Shooting Star" grips which were custom made to my hand pattern way back in the '60s. Easily the most comfortable and effective grips for a J-frame I've ever used - at the expense of a bit more bulk.
I find the Barami Hip-Grips to be the most useful and versatile grips for concealed carry. Here's another set on a 442:
This Model 317 has a set of Dymondwood boot grips that used to be offered as an option by S&W. They are no longer made, but they are very light and compact. I like this setup for ankle carry. You might be able to scare up a pair on eBay or at gun shows.
Hope these pics will give you some useful options.
