I have 4 S&W J-frames.The model 60 is is the cream of the crop in its class. But be prepared for stiff recoil in .357 magnum especially with small wood grips. If you are looking at smooth rosewood grips they are beautiful but too slick to be practical for shooting.
I carry .38 +P. You will need to try it yourself to see what your limits are.
I like Pachmayr Compac grips for shoot-ability. They cushion recoil and have a place for the pinkie finger. They do add a little weight and bulk. If deep concealment is the objective of the day I go with factory wood grips and a Tyler T-grip adapter.
The "weight" of the model 60 has never been a problem for me. I prefer it over the lightweights.
