Abstract: This invention relates to a reinforcing arrangement for strengthening the back seam and outer face of a holster for guns or like items. The reinforcing arrangement of the present invention is comprised of a reinforcing piece which is attached to the inner surface of the holster's outer wall. The reinforcing piece includes a protruding arm which extends outward from the back seam. The protruding arm is folded around the back edge of the holster's outer wall so that a portion of the arm overlaps the outer surface of the outer wall. A rivet is then used to further secure the inner and outer walls of the holster to each other. The rivet passes through a channel which is formed by a hole in the portion of the arm which overlaps the outer surface of the outer wall, a hole in the outer wall of the holster, a hole in the portion of the arm which passes between the back edges of the holster's outer and inner walls, and a hole in the holster's inner wall.
