S.C. Code Ann. § 23-6-240: Authority to carry pistols.

Notwithstanding any other provision of law, constables who have received the required training shall be authorized by the director to carry pistols on and about their persons unless otherwise restricted by the director in writing. However, the director, after hearing and for cause, may deny such privilege to any constable pursuant to this section who is guilty of using his pistol at any time in a manner inconsistent with accepted law enforcement procedures as determined by the director or who has been convicted of any crime for which a penalty of imprisonment for more than one year may be imposed. The term "conviction" shall include a plea of guilty, a plea of nolo contendere, or forfeiture of bail.
