Abstract: A quick-release lockable long gun case encloses the breech, trigger guard and trigger of a long gun allowing the barrel and stock to protrude through oppositely disposed openings. A keypad may be preprogrammed with a combination that must be entered to allow access to the long gun. A key operated override mechanism is also provided. An internal chamber contains a removable insert having the outer configuration conforming to the breech, trigger guard and trigger of the long gun. The lid is hinged to the body with a spring biasing the lid in the direction of opening. The latch mechanism includes a strike attached to the lid of the long gun case and a latch mounted within the body of the long gun case. The latch is pivotable and has upper and lower structures that are balanced about the pivot point thereof.
