Abstract: A handgun holster includes a strap which is adjustably positionable on a wearer's belt, and a bluing protection pad having one end adjustably secured to the strap and the other end to the belt. In use, the bluing protection pad is folded between the belt and the strap to define an adjustable gun receiving pocket capable of securing a wide variety of handguns. The interior of the gun receiving pocket is lined to protect and preserve the gun's blued finish, and such protection is enhanced by the treatment of the liner with a light film of oil.
