Found out California bans the .410/.45LC combination specifically. Go figure. It's a state thing but not a federal thing.

Check that out. There aren't much of any pistol based .410 performance data that's worth doing. Out of a full sized shotgun, there are some decent performers, BUT I can't think of any reason to do it UNLESS the .410 shotgun was ALL you had.
Another funny thing about the Judge is the "snake" thing. People carry it for snake protection, but given the tests, what you'd have to do is shoot 2 or 3 rounds REALLY close and HOPE the snake doesn't strike. The .410 just doesn't have enough payload to reliably get snake kills with one shot. So, in direct terms, here are your choices if you run across a dangerous snake. You stand still in the danger zone, pull the gun, shoot once, hope the snake doesn't strike and/or you kill it, fire again and AGAIN hope you kill it and/or it doesn't strike, rinse and repeat . . . OR . . . you can take 2 steps away and both of you leave unharmed.
Meh . . .
THAT BEING SAID, by all accounts the Judge is a well made gun . . . and I'm a Taurus fan to boot. LOL!
