It honestly looks like you have/ have listed the bare essentials for a class. Everything else that you might be able to think of is optional. ie hydration pack etc.
Load is 3 in the chest rig, 2 on the belt. There is room on the chest rig for 2 pistol or light pouches. I am trying to figure out the best place to pit the pistol mags.
I can put one easily accessable on the minimav but the belt is running out of accessable room. I wonder if I should move the dump pouch further back. But then it would be very hard to access.
The pouches they use absolutely blow, but you can get just the innards and jam them into a no-kidding blow-out kit bag of your choosing. Tricky part is usually putting it in such a place, on your belt or your chest, that you can reach it with either hand.
I ended up going to both lines, given that my belt is the first thing I put on and is designed to act as a stand-alone. Belt’s got a TK and a wound dressing on it, forward of my holster close to the belt buckle. Plate carrier has a more complete kit (NP tube, 14ga needle, gloves, another TK) immediately above the belt’s med stuff. All reachable by either of my hands and still out of the way of the stuff I use all the time (ammo, tools)
