Its a legitimate question if the gun does not belong to him. NC does not address the lending of guns in its law, but rather uses vague terms.
"§ 14‑402. Sale of certain weapons without permit forbidden.
(a) It is unlawful for any person, firm, or corporation in this State to sell, give away, or transfer, or to purchase or receive, at any place within this State from any other place within or without the State any pistol or crossbow unless: (i) a license or permit is first obtained under this Article by the purchaser or receiver from the sheriff of the county in which the purchaser or receiver resides; or (ii) a valid North Carolina concealed handgun permit is held under Article 54B of this Chapter by the purchaser or receiver who must be a resident of the State at the time of the purchase."
Does the loan of a gun fall under giving, transferring, or receiving? We're going to say no, since the law doesn't specifically address the loaning of a gun.
Maybe the guy wanted to cover his behind.
