Physical work and concealed carry
I still to this day do not know how I have hurt myself but there were times that I was carrying IWB and bruised my hips and couldn’t carry the gun for awhile. I think it was possible from driving in a car for a long time and had the seat belt kind of squeeze the gun up against me a little more. That is still to this day the most annoying thing about driving is having to put a seat belt on and carrying a medium or large firearm on your belt.
I much rather carry on a shoulder rig, but that is not a very good CCW method in warm weather and the should harness can be a dead giveaway. Galco holsters makes the nicest leather holsters and the Miami Vice Classic should holsters looks the best when when wearing a suit and tie. I think the real reason everyone is moving towards pocket carry as an option is there is really very little discomfort for every day carry.
