A gun holder includes a central shaft; and a holder part, which has slots formed such that a plurality of guns is respectively and radially held around the central shaft, and is rotatable around the central shaft. The gun holder enables a user to take out a gun assigned only to the user and simply prevents other guns from being withdrawn, and has a locking means corresponding to respective guns when the guns are stored, wherein the locking means is operated by one actuator, thereby enabling power consumption and manufacturing costs to be reduced.
