IWB-Appendix here. I'm using a High Noon Hidden Ally (tuckable version of Mr. Softy, which is the non-canted version of the Bare Asset depicted in DawgFVR's post above). This is a very low-riding holster, which is what I wanted for concealment purposes. A higher riding holster would make for a faster draw, but it'd print against the front of my shirt more too.
Despite lacking a reinforced mouth, I can easily reholster one-handed with this when carrying appendix. If I were carrying strong side, I would definitely want a holster with a reinforced mouth for easier reholstering - makes for much easier fast-draw practice.
Love this holster. I'm 5'11", 170.
