S.C. Code Ann. § 16-23-405: Definition of "weapon"; confiscation and disposition of weapons used in commission or in furtherance of crime.

(A) Except for the provisions relating to rifles and shotguns in Section 16-23-460, as used in this chapter, "weapon" means firearm (rifle, shotgun, pistol, or similar device that propels a projectile through the energy of an explosive), a blackjack, a metal pipe or pole, or any other type of device, or object which may be used to inflict bodily injury or death.

(B) A person convicted of a crime, in addition to a penalty, shall have a weapon used in the commission or in furtherance of the crime confiscated. Each weapon must be delivered to the chief of police of the municipality or to the sheriff of the county if the violation occurred outside the corporate limits of a municipality. The law enforcement agency that receives the confiscated weapon may use it within the agency, transfer it to another law enforcement agency for the lawful use of that agency, trade it with a retail dealer licensed to sell pistols in this State for a pistol or other equipment approved by the agency, or destroy it. A weapon may not be disposed of until the results of all legal proceedings in which it may be involved are finally determined. A firearm seized by the State Law Enforcement Division may be kept by the division for use by its forensic laboratory.
