For work I found one of the KDH carriers and modified it with a Mayflower cummerbund adapter. It's not a perfect solution but makes it more bearable that the garbage issued side plate carriers it comes with. If I get forced to wear the 8lbs of issued side plates I use the SKD PID side plate pouches. They hold the plates pretty securely but take up a lot of space on the outside of the cummerbund. I found an extra cummerbund front flap from Eagle for cheap, chopped off the front piece so it was just exposed Velcro on the front. bought a placard adapter buckles from downrange gear. Now Ive got the issued POS set up in a way that works and is fairly comfortable. I just run 3 mags on a placard on the front, a nods pouch, maybe a camelback then the rest of my shit on a belt. I need to put some miles on it and try it out at the range but I think it will work for me and not get to much attention from uniform Nazis if I ever get back to the line.
There are some new slick PCs out that that look pretty interesting. I really want to get my hands on one of the spiritus systems rigs.
I think it would be pretty handy for classes and as a contingency type PC.
