Been using a Crye Lopro Blast Belt since 2011 or so. Inner/outer cop belts are popular now but I hate them and find war belts with standard PALS loop much more comfortable and secure. YMMV id just try a few you like and sell if you dont like it.
I like how comfortable and easy to rotate the blast belt it. Carries weight on the hips and you can use suspenders if you wanted. Clears the plate carrier easily and the inserts are piece of mind for taking shrapnel in thr bowls of my hips or lower back. Has slots underneath to route a mid ride holster and optionally a gas mask pouch on your weakside
I carry 4x rifle mags, 2 radios, 3 tqs, an IFAK in a dangler, an ATAK +meshtastic and water on my plate carrier and 2x pistol, 1x rifle, 1x tq, med kit, dump, utility (gerber, cleaning kit, etc) and holster plus a knife and grenade pouch on my Blast Belt. Replaced the inner belt with a Qore for more durability over the shitty plastic buckles.
I use an old issued JPC 2.0 primarily but also have an issued LV-MBAV I wear a Spiritus Mark IV over with a Thing 2. That can hold 4x rifle, 3-5x pistol, medical in a dangler, and an extra sustainment pouch plus radios but without the relocation kits. Also some room under the half flap if I only carry 2x pistol. Slap a Microbat candy pouch in front or AXL Sandwich bag in rear for extra admin room
More crap goes in a SATL but I could fight off my belt and stuff my radios and ATAK into my pockets if some ill fate should befall my plate carrier. Even more flexibility if I opt for the LVMBAV
