Sorry, I've been out of town for a while.
My main concern here is not losing equipment at the range. I don't carry, I just shoot "for fun" with a couple of buddies. If I were in an actual gunfight, I'm pretty sure that I wouldn't be more concerned with getting rounds downrange than with damage to replaceable magazines.
Mainly, I just don't want to drop my magazines on the ground or in the snow. Y'all have given some great ideas, and I appreciate it!
