South Carolina is now a constitutional carry state. I am very grateful that I have a card in my wallet that says that I have passed a background check and can intelligently do this versus all the MFs that are going to get themselves into trouble because they didn't take a class proving that they know what they're doing and learning when they can and cannot use a weapon. Things are about to get interesting in South Carolina.
From my reading of the law it only allows open carry by people that do not have a permit to conceal carry. And a very key thing to remember is that you can only use a gun to defend yourself or someone else in a life threatening situation. This is not the same as using a gun to protect property. I have sat through multiple classes on when you can and cannot pull a weapon and a lot of people in those classes do not understand that fine detail. If someone is trying to steal something you cannot pull a gun. Only if you or someone else is in a life-threatening situation is it permissible to pull a gun. Anything else could land you in jail.
