Yes, AIWB daily since 2020.
I installed a Striker Control Device on my Glock 19 MOS since I was used to thumbing the hammer on my HKs, holstering. In 2021 I switched to a P365X and sold the G19, as the small Sig just plain worked better for me all around. I use made-for-AIWB kydex holsters by either JM Custom Kydex or Dark Star Gear. Always condition 1.
Current EDC is my Sig Sauer P365X, 12+1 with Speer GD 124+p, Wilson Combat grip module+weights, and a HS 407k. I use a JM Custom Kydex AIWB 2.5 Wing Claw and a single DCC clip (I asked Tony to put in both upper and lower holes so I could try either DCC clips or PTD.) Belt is a Mastermind Tactics Specialist Pro.
I attached a Mastermind Tactics Appendix Carry Pillow on the reverse. The ACP helps cushion the holster against my, ah, gentleman area. I find the ACPs are a better fit and more comfortable than harder foam wedge type pads I've tried.
I don't wear an undershirt (Florida, too hot) so I velcro'd another ACP, this one without any stuffing, to act as a cloth spacer against my skin, on the upper part of the holster sweat guard.

I have another AIWB holster by DSG, I use for my Ruger LCR .38. This is for when I go to the gym. It has a single steel wide clip I attach to my gym shorts. T-shirt over. I wear it in the same AIWB position as the Sig. I don't go nuts a the gym, just elliptical or walk, and lift free weights. Otherwise I pocket carry the LCR in a Desantis Nemesis as a BUG.
I gravitated towards Appendix carry after I went on a low-carb diet and went from 215 lbs to 180, and 38" pants to 34". Having lost the weight made this a much more attractive option for me. I find it very comfortable walking, driving the truck, camping, eating dinner out, etc. etc.
I think Appendix isn't for everybody; whether its from perceived risk management (and I get that), or your body being a shape, not um, conducive to Appendix, or being already used to another carry type (behind the hip, say) that works for them. In that case, great. So it kinda depends on your personal circumstances.
