I heard somewhere that if you pee on your feet you wont get athlete's foot.
I'm pretty sure whoever told me that just wanted to see if they could get me to pee on myself.
I guess, the moral of the story is this.... don't believe everything you hear. The best way to break in a holster is to get it to form to the gun. The best way get the holster to form to the gun, is to have the gun in it, whether you're wearing it or not. That is my experience after having broken in (no lie) a dozen or so holsters.
YMMV of course.
