I've used every possible configuration to hold gear. Including having everything on a huge Batman Belt.
The Batman Belt is simply too heavy and bulky for my taste.
A handgun, pistol mags, rifle mags, and shotgun ammo all on one belt is really uncomfortable for me.
Also the fact that ammo ends up all the way around the belt, so now I need to reach behind my back to grab it.
I would much rather move some of that stuff to a small chest-rig.
Much less strain on my lower back. And everything is easy to see, and easy to grab.
Blue Force Gear makes some really nice chest-rigs. Very light and comfortable.
Pouches do not have velcro flaps, or anything else to slow you down.
