I don't even consider my TC contender's .410/45 colt barrel "useful" vs a real shotgun.
Inside 20 yards, it patterns well, but the screw on choke (must be off to fire .45 Colt) stops the rotation of the shot string AND chokes it full choke, so 20 yards or a smidge beyond, I can hit birds, rabbit, what not with it and have. When dove season starts, I have a real shotgun, though.
The Judge/Governor have limited use and NONE of that use is field or hunting use. That's not opinion, that's just plain fact. I'm a wing shooter big time. My smallest gun is a 20 gauge coach gun I use for doves. I have 3 12s for bird hunting and two of 'em made good duck guns, I hunt a lot of ducks. I have a 10 gauge for goose hunting, shoot large payloads of big T steel shot (mandated by law).
Yes, the .410 revolvers are meant for self defense, but give me a .357 magnum...or my .45ACP or one of my 9s or even a .38. A judge is HUGE, won't fit in a pocket, makes a stupid carry piece IMHO, so many better guns out there. For home defense, I have my coach gun loaded with 3 buck and my daily carry by the bed, either 9mm, .38 special or my 3" .357 Magnum or my Ruger .45ACP. None of those are broke and it's MHO that if they were, no .410 shell would be the fix.
