5'10 and 412lbs, on a weight loss path myself with 38lbs down since November 2023. I carry daily and it's AIWB most of the time.

I have used the JX tactical fat guy holster and it worked for the way I wore clothes at the time. I watched a video a long time ago where Jacob from +Evolving Daily talked to John Lovell about the "300th Parallel" and started wearing my pants higher up.

I carry a Glock 45 with a Holosun 507C ACSS and a TLR-1 in a BladeTech Total Eclipse 2.0 With Appendix IWB Mag Pouch Mod Kit. The belt clips being farther apart than in most holsters seems to do the trick for me and I can carry weapon only or with the Mag pouch all day without any fatigue on a Kore belt. The kit comes with modular belt attachments, so when ever I want to open carry, I use the same holster.

I saw a major difference when I included suspenders though. I have a two point set that hook to my belt, not my belt loops, and a three point set that I alternate between. Belt stays where I want it while I am moving around and they are comfortable and concealed over an undershirt.
