A holster for a weapon such as an electric discharge weapon is made from two pieces joined together to form the holster end wall. The holster right piece has a right end wall part that is molded with both thin wall and also selected thick wall areas that are intentionally molded as thick wall areas. The holster left piece has a left end wall part that is molded to have both thin wall and also selected thick wall areas that are intentionally molded as thick wall areas. When assembled, thin wall areas of the left end wall part overlap thin wall areas of the right end wall part to thereby form a first thick wall region of the holster end wall. Thick wall areas of the right piece end wall part interfit with thick wall areas of the left piece end wall part to form a second thick wall region of the holster end wall.
