I'll second or third or whatever a S&W in either .38 or .357. Being a BUG, you'll be point shooting if you need to use it, the .357 will be a hand bruiser. I had a J frame (model 60) with a three inch barrel, didn't care to fire magnums in it.
I carry a Taurus Ultra-Lite .38 special.. love it!
I have a J-Frame Ultralight S&W and it kills me to shoot it. The recoil drives me nuts. I do like the fact that it's easy to carry, though. My other J-frame is heavier, but it's so much easier to fire.
