And Rat - you might go w/ +P loads for carry - but I don't think you'd want to shoot those hot rounds when you're just out plinking.

Andy W - wasn't trying to undercut your post - if I was going w/ even a mid sized revolver I'd agree w/ you on .357 - definately a little more knockdown and easier to find ammo - but on something pocket sized, I think that the .38 is a little better suited, and that the features of the 642 are crucial. Then again, I'm biased, since I pack one ever day. Definately handle one if you get a chance though - you'll be blown away.
