I'll add my two cents. I carried forever in a Coronado concealment vest. I carried Kahr P40's. If there was only one carried on in the left inner pocket, I was constantly pulling down on the right side to even it out. But my solution was to carry my second P40 in the right side. Definitely needs counter balance. Secondly, I had a motorcycle accident last October and came down on my left side. Broken rib right about where the gun would ride in the pocket. I believe my arm was along my side also, judging by the road rash, but don't remember feeling it there. I believe if the gun weren't there I wouldn't have broken the rib. Not faulting the vest, but I never thought of that and happily wore the vest and carried as designed. I don't how to avoid this happening. Any way something for you to consider. Be careful out there.
