Open and Concealed Gun Carry Laws in South Carolina by Monica Steiner, Contributing Author
South Carolina protects the right to bear arms under Article I, Section 20 of the state constitution, but this does not mean that everyone may carry a gun, or that you may always carry a gun wherever you like. South Carolina requires a concealable carry permit to carry a weapon openly or concealed on (or near) you body or vehicle unless you are in your house, at your place of business, or on your own property. (S.C. Code Ann.§ 16-23-20.)
