I too use a Circuit Judge for home defense. A small easy to move around with package is what I'm after. It has an 18 1/2 inch barrel and a pistol grip style stock. It's very easy to move around with this gun, I even took mine deer hunting this year. The sights are great and the overall feel of the gun is unmatched. It's also extremely light. I absolutely love this gun.
I was using 3 inch 000 in mine for home defense, but currently it's loaded with LeveRevolution .45 Colts.
For what it's worth, I also use an o/u 12 gauge with 3 inch #4, Winchester turkey loads.
Next idea is to use my Rifled Mossberg with mini slugs. Or maybe just Sabot Remington hollow points. They do incredible damage.
