It used to be mags were treated poorly and expected to take the abuse and keep working. experience has shown you are MUCH better offer treating your mags like you may need them, than as a piece of junk. Don't drop them, it takes nothing to catch them and keep them from unnecessary damage. dropping them free is needless, useless and will wear them out prematurely, its just not necessary especially in training. They are an integral part of the whole system look after them, there is no reason not too.
