The Double Dog features a steel frame for increased strength along with a ported barrel to vent gasses upwards, fighting recoil and allowing for a flatter shooting revolver. The revolver also comes with an additional cylinder for different chamberings allowing for a wide variety of ammunition to be used. This model features an all-black finish with walnut grips and is chambered in .357 Magnum. One 9mm Luger cylinder is also included.
