For CCW guns, its boot grips for me.
I order Ahrends Cocobolo finger grove grips for my J frame. I order them unfinished. That way I can work on them with some 80 grip to get a fine, personal fit. Then, after working down to 220 grit, I apply several coats of Tung oil. I don't see the logic of big grips on a small concealable revolver. If I use larger grips, I can also use a larger gun (K frame snub). I have a similar philosophy about barrel length. 2 inches for a J frame and 2.5 or 3 inches for a K or L frame, for CCW.
Best,
Rick
