Anybody have any ideas for easy to access ammo pouches? I'm thinking something that might clip onto your belt, have some king of hold-open mechanism, and also a hold-closed mechanism. I was thinking of getting a rock climbing "chalk bag". Something like this: http://www.rei.com/product/801346 I don't know how big this particular one is, but the ones I've seen my daughter using climbing are baseball to softball sized. Anybody tried something like this? Worthwhile, or a waste of time/money? I'm getting tired of bending over to my can of ammo on the ground after every shot.
