Many IWB holsters are versatile and adjustable. Start with one of those. Mine is a Klinger but there are plenty of options. You can adjust the angle etc and it has a comfort pad. My question about appendix carry is taking a wizz. Will it dump the gun if you undo your pants for clearance? What about taking a crap. Life happens when you carry.
Taking a whiz or a dump is another reason to consider pocket carry. No worry about the gun falling to the floor or even resting on the floor while your pants are down around your ankles.
The only rule I would add if you decide to try pocket carry is that only the holstered gun should be in the pocket, absolutely nothing else. Then there is no reason to be reaching into that pocket except to put your hand on the gun and draw if needed. Some feel that a disadvantage of pocket carry is that drawing when seated is hard or impossible, but for many folks the same is true for IWB when seated. Another disadvantage, which hardly ever applies for me, is that wearing dress pants of lighter material can make pocket carry less than ideal as the weight of even a light gun will pull the pocket down. But in jeans or heavy cotton pants or shorts, pocket carry works just fine. And pocket holsters are easy to use and inexpensive.
