Sounds like a Fanny Pack to me...
My wife wants a form of storage pouch for ammo to keep on herself. We have Randy Cain's handgun course coming up in a couple of weeks. We already have extra mags. But, we don't have time during session to run back and reload. I use cargo shorts and pile up the ammo in the pockets. She isn't so keen on that idea.
Any ideas instead of getting a "Fanny Pack"?
