Good quality, well designed, functional holsters for concealment are very difficult to find, especially locally. Ordering on line is a pain because unless you can talk to the maker and describe body differences and personal desires, you may be waiting a considerable time for a holster that ends up in a drawer.
I have found a local engineer who does good work and understands what it takes to wear a holster concealed for extended periods of time. I highly recommend his products. Here is the front and back view of one of the inside-the-waistband-tuckable holsters he made for my backup gun, which I carry cross draw-left side. This design also worked right side appendix.
Send him an email and describe what you need/want. You will not be disappointed.
