Police returned the .32-caliber semiautomatic pistol to Columbia lawyer James Corley.
The local prosecutor said this month that Mr. Corley's shooting of 18-year-old Kayson Helms of Edison, N.J., was justifiable self-defense of himself and others at the center.
The 61-year-old Mr. Corley has a concealed-weapons permit.
Police say Mr. Helms already had robbed one person at gunpoint and was about to rob others when Mr. Corley shot him.
