Thanks for the help, everyone. After reading everyone's posts I've decided to abandon the 9mm idea and the small-enough-to-jog-with idea. I'd like to go with a 357, stainless, 3 or 4 inch barrel. I need something that will handle snake shot well and can stand up the the elements. I like S&W but prefer something without the new locking mechanisms that they're putting on now.
Any final suggestions before I go out and buy something?
A pre-lock 686 if you want the Smith. Again, for the money it's hard to beat a Ruger. Speed/Security Six or the GP100/SP101 for something easier to find.
