Why are you intentionally dropping magazines on a concrete floor? Just don't care, or trying to find out if they'll break?
Ever heard of a speed reload or training like you fight? You going to hang onto empty mags?
The fact that I'm most likely going to do an administrative reload (replace a partial mag with a full mag) if I need to means yes, I train to hang on to my mags. I'm not a gun gamer, all my training is for fighting not competition.
