The Taurus 4510 is a five shot revolver designed and produced by Taurus International, chambered for .410 bore shot shells and the .45 Colt cartridge. Taurus promotes the Judge as a self-defense tool against carjacking and for home protection.
There have been two model number designations for this firearm, the 4410 (no longer produced) and the 4510 (current). Both model numbers are essentially the same revolver, and any 4410 or 4510 will yield basically the same performance. taurus 4510
It got its name “The Judge” in 2006 when Bob Morrison, Executive Vice President, learned that judges in high-crime areas of Miami, Florida,
were purchasing the revolver for personal defense in their courtrooms, and after Morrison investigated further, the model designation was changed from 4410 to 4510 to more accurately reflect the revolver’s versatility (.45 Colt + 410 shot → “4510”) Taurus International reports that the Judge is their top-selling firearm.
