I live in Pennsylvania and have a CC permit (LTCF). PA. is also an open carry state as is many around the country. As I understand it OC is permitted (except Philly) with the OC on the waist, shoulder holster, etc. but must not be covered as in CC. This begs the question, why bother to obtain a CC if OC is legal ? I can understand many reasons why someone would want to conceal, what I don't understand is if you CC and your gun shows are you violating the law, and if so how can that be if OC is permitted ?
