The Taurus® Judge® Double-Action Revolver features a solid steel frame, cylinder, and barrel. The cylinder is chambered for 2-1/2″ .410 shotgun shells, or .45 Colt cartridges; and the barrel is rifled. An extended ejector rod kicks out fired cases with ease. Taurus rubber grip absorbs recoil and enhances user control. The fixed rear sight and a high-visibility, fiber-optic front sight are both rugged and easy to see. The Judge Defender can be used as both a double- or single-action revolver. An exposed hammer allows you to cock and fire the revolver in single-action mode; and a transfer bar safety mechanism prevents the hammer from striking the firing pin unless the trigger is pulled fully to the rear. The Judge Double-Action Revolver utilizes the Taurus Security System® (TSS), enabling you to disable the weapon completely with the turn of a key.
