In response to the OP's original post I carry my full size PX4 9mm in a Theis holster with a 5.11 belt then my basketball shorts over that. I also usually have a kershaw leek on my wasitband also. Now I don't really run, I go for walks and occasionally jog and this setup works fine for that. If I were running I would probably would carry something smaller. As far as odds of attack who knows but if it happens I have options to protect my self whether from a BG, dog, coyote or anything. I've never had a gun drawn on me or my life threatened by someone else doing any activity so far but will do my best to be prepared regardless of when or where it may happen.
