Bumping this topic. Still piecing together my gear, but here's what I have so far.
Plate carrier has 3 AR mag holder across the front and a small zipper pouch for "stuff."
Belt has a 2 AR mag holder on left side, and 1 AR mag/1 pistol mag holder on right side.
I think I might put a small roll up dump pouch on the back side of the belt, but I'm trying to keep things simple and not overload.
The plate carrier doesn't have any plates in it yet. Still doing some research and deciding exactly what I want.
Also still need to get my backpack loaded up. It will have first aid in it for sure, but other that that I might go through a couple different iterations of what exactly I keep in there.
