For appendix folks, this is the most comfortable AIWB holster I've tried. It is full kydex with an offset belt clip. The wing is an option and I recommend it to aid in concealment.
Gun choices are limited to popular models, but Nate said that he will expand his line up. I specifically have the Skinny Rig holster with wing. I wear it at 12:00 for my Shield and P320C.
