For years, my EDC has ridden in an IWB holster at about 3:30, now am thinking about trying AIWB carry. I put my kydex IWB holster in the AIWB position to see what it would feel like but it printed horribly. I would appreciate any suggestion for a good AIWB holster for a Glock 43X. I found the appendix carry very comfortable so it may become my preferred carry.

Try the Phlster Skeleton. I've had one for a 365 for over a year. It's pretty good.

I’m a big fan of Tenicor. https://tenicor.com/collection...wb-holster-for-glock

Or JM Kydex.

My G43 and G43X both ride in the same Mitch Rosen Independent.

AIWB can be an acquired taste. I've had good success with this combination. Whether it's a thing or my imagination, I've found leather to be more comfortable than Kydex.

The Go To folks in AIWB are Spencers Keepers, Dark Star Gear, and Tenicor. All three are well thought of in the combatives in a weapons based environment community.

Tenicor is what I currently use. I also have good results with G-Code, Zorn and JM Custom.

Thanks to all for the info and links, now I need to spend some time on the iPad. I am leaning toward the JM Custom for the soft loops/pull the dot snaps.

JM does good work, I have some of their OWBs.

Not sure if he is still making holsters as he had a medical issue, but I can definitely state a black label holster in aiwb (kydex with the belt bump) is not only comfortable but totally concealable for a 43x. If that is no longer an option, then email Kee at rmholsters and get a low rider specifically setup for aiwb (straight drop). I exclusively carry aiwb due to back issues and have a low rider for all of my carry guns.

Love my Veil Solutions Apex. Worn it every day for 4 years. I'll be looking at Tenicor as an alternative just to try new things.

I use a G-Code Eclipse with my Sig P365X in AIWB. The Kydex has a fuzzy exterior that is comfortable and a little bit grippy. AIWB is the most comfortable way for me to carry.

The Vedder Light Tuck with claw works best for me. I like having the option of being able to tuck in a shirt if needed.
