A size up from the standard Taurus Judge the Judge Magnum has a 3 chamber rather than the Judges 2.5 chamber. The Judge Magnum is capable of firing 45 Long Colt or 410 shotgun shells and is available with either a 3 or 6.5 barrel. The more powerful 6.5 barrel provides added power while maintaining flexibility in ammunition selection. The double-action Judge Magnum comes standard with a rubber grip fiber optic front sight and the key operated Taurus Security System. Shallow rifling of the barrel means the Judge is not a short barrel shotgun under the NFA though it is illegal in California due to that states more stringent gun laws.DetailsFinish Blue Steel - Caliber .45.410 (3 chamber) - Grips Ribber - Capacity 5 - Weight 37 oz - Rate of Twist 112 - Barrel Length 3 - Frame Compact - Action DASA - Front Sight Red Fiber Optic Fixed - Length 9.5 - Grooves 6
