I have this idea in my head that I want a somewhat discreet messenger-style bag that would hold roughly 3 rifle mags and 3 pistol mags along with some basic survival stuff (fire starter, water tabs, power bars, etc). The idea being let's say I'm driving home from work and some stupid rioting/looting/terror event happens. I'd like to be able to grab and go without looking all kitted up with something like a chest rig. I use the Comp-tac clip-on mag carriers and the thought is to feed the gun from the belt pouch and then feed the pouch from the bag. Anyone have such a thing? I've looked at Maxpedition, London Bridge, and 5.11. Thanks for any thoughts/experience!
