A bracket mountable on a door hinge for supporting a gun holder behind an open door. The bracket includes a docking station and an adapter. The docking station mounts to the hinge. The adapter attaches to any gun holder, such as a holster. The gun is stowed in the gun holder on the docking station until needed. When needed, the gun is withdrawn from the mounted holster. Or, the holstered gun with the adapter attached can be lifted out of the docking station to carry or relocate it. Alternately, the gun holder may be a magnet with or without a magnetically transparent holster. The magnet stays attached to the adapter, which is left in the docking station. The gun—holstered or unholstered—adheres magnetically to the bracketed magnet. When needed, the gun is pulled off the magnet and returned to a carry position.
