what would be the lightest, most compact and easily concealable setup you can think of for jogging? I was thinking maybe some really small aluminum or titanium revolver with a built in clip on the handle or something along those lines. Thinking about picking something up at the gunshow this weekend. I would probably be content with a 22lr or 22mag even... Needs to be light enough to attach to gym shorts without any one noticing or having it fall off.
