Built into the body of the holster, (between the leather layers,) there is an integrated steel frame which can be bent with pressure on the sides or ends. After bending, it should hold its new shape. Holster is too round, pistol is loose If the holster mouth is too CIRCULAR, and your pistol feels loose and will not slide down far enough, Press down on the side of the Holster to make the opening more oval Holster is too flat, pistol is tight If the holster mouth is too FLAT, and tight against the sides of the pistol frame, Squeeze the ends to widen the opening.
