I agree with Kirk. This may be an essay way to conceal, but I have never found it comfortable. Try sitting down for a while or driving and seeing how well you can draw. In a situation where I need my cc the last place I want it pointed is my man business .
14 hour drive from Virginia with a G26 AIWB was no problem. I find AIWB even more comfortable than OWB at 3:00-4:00. The right holster in the right location on the body makes all the difference in the world. A G19 is even more comfortable since there is a larger surface area that's pressed against the body.
