I throw in with Snubbyfan. I don't have particularly meaty hands but mine are very long and I have always preferred the Pachmayr Compac on round-butt J-frames, if a rubber grip is to be used.

You might also look at the Hogue Tamer model. Both of these grios, though of fairly different styles, feel good in my hand. I don't have a lot of experience with the Tamer just now, but it looks promising - if it's unusual attachment mechanism works over the long haul. Testing it now.
