S.C. Code Ann. § 23-31-245: Openly carrying a weapon.

A person openly carrying a weapon in accordance with this article does not give a law enforcement officer reasonable suspicion or probable cause to search, detain, or arrest the person. This article does not prevent a law enforcement officer from searching, detaining, or arresting a person when he has a particularized and objective basis for suspecting the particular person stopped of criminal activity. A person merely carrying a weapon in accordance with this article is not sufficient to justify a search, detention, or arrest.
