In the LEO world chest rigs are great because mos guys belts are already full with a few pairs of cuffs, gun, handgun mags, taser, baton, peper spray, radio flashlight etc. So for LEOs a quick chest rig or plate carrier that they can put on is best. for civilians who may be responding to an emergency in their neighborhood, work or for self defense a battle belt is great because it can be lower profile and can hold everything you need, Pistol, mags, blowout kit, flashlight dump pouch etc. Right now I have a plate carrier setup and a slim/light blueforce gear chest rig. The blueforce tenspeed chest rig is as light as air when not filled, is low profile and holds 4 mags. As long as you do not fill up the molle on both sides you can zip a jacket over it even fully loaded and none will be the wiser. In prone exercises i had no difficulty. However, I always run a primary reload in a rifle mag pouch on my belt and the 4 on my vest are secondary reload.
