Look at something in the way of a belly band holster. Brave Response Appendix Holster is one. This conceals better than any "traditional" belt mounted holster I have tried. There are draw backs to belly band holsters. The holster will collapse when the gun is drawn. If it is mandatory for you that the holster stay open for re-holstering, this is a concern. Belly bands, and leather holsters for that matter, will soak up sweat. Leather holsters can taken hours to dry out. A belly band not so long. One good thing about belly band type holsters is that you don't get rigid portions of the holster poking you. This can happen with some leather holsters as well as kydex. Design of a specific holster plays a big part in this. I have been using appendix carry for almost 30 years, with it being 99% exclusive for the last 25 years, so it really isn't that difficult.
Carrying IWB in any position is impossible for some. I guess it is a matter of just deciding that you want to and go with it.
At any rate, just experiment, that is a small part of the fun of the whole thing.
Chances are you will wind up with a drawer full of holsters, like a lot of us.
