Not really a good home defense choice though. Put the .45LC rounds in it.

I agree that any most .410 shot shell loads are pretty useless except for snakes (or perhaps issuing a wide area wake-up call). I have worked with #4 and #7 shot loads at 15' thru my judge and they completely and evenly cover a large silhouette target (probably with considerable overspray.)
I agree that .410 slugs are useless when you have the option of using .45LC instead.
.410 000 is another matter. I have had absolutley no problem finding a variety of 2.5" handgun loads. In my area, I've had a lot more trouble finding .45LC than .410 handgun ammo. Winchester packs 3 pellets to the shell and Federal makes a 4 pellet load, each with a muzzle velocity over 1200fps. Each pellet is essentially the diameter of a .38 and I usually get about an 8-10" group at 15' on a large silhouette at the range. Five pulls of the trigger and target is pretty much destroyed. Precise shot placement is not an issue, it's pretty much point and click.
And the reviewer should note the Judge is available with a 2.5" chamber OR a 3" chamber.
