I appendix carry IWB about 95% of the time. I am 5'-9"/170 lbs. I never got comfortable carrying at the 4 o'clock position because I always felt like I was printing badly or it was uncomfortable while driving. Not to mention hard to access in a pinch in the car.
AIWB simply works best for me. Speed of presentation, comfort, on/off convenience, etc. Are optimum for me.
I don't use an appendix specific holster. But it worked out to be perfect for my application. The don Hume h715 is a gun specific molded leather holster with zero cant and a strong metal clip. I know for certain the trigger housing is securely enclosed, and the mouth of the holster is reinforced for easier reholstering. Best of all is the price! $35 on average. Handling them in person you would think they cost a lot more. I now have one for all my subcompacts. Here are a few.
