Abstract: A holster for a handgun comprises a case for receiving the handgun and a flap member mounted on the case. The flap member provides a cover member for the handgun having an offset hinge associated therewith. The offset hinge comprises a pair of spaced apart arms extending from the cover member and pivotally mounted to the case to provide for swinging movement of the cover through a path clear of the case between open and closed positions. In the open position the cover member is clear of the top of the case and at an over-center position relative to the axis of pivot so as to be maintained thereat. Snap fasteners, separate from the offset hinge, secure the cover to the case in the closed position to assure a maximum degree of safety, security and protection to the holstered handgun.
