A permit recognized by SC gives you the ability to carry a concealable weapon while out in public. Here is the definition of a concealable weapon - SECTION 23-31-210 (6):
"Concealable weapon" means a firearm having a length of less than twelve inches measured along its greatest dimension that must be carried in a manner that is hidden from public view in normal wear of clothing except when needed for self-defense, defense of others, and the protection of real or personal property."
Places "off limits", even with a permit, Section 23-31-215 (M):
