I would disagree with anybody that would claim the Judge is not a good choice for personal, home or vehicle defense.
And my opinion comes from owning and shooting the 3" chamber magnum model, unlike many that like to chime in with an opinion with no personal experience.
No, the Judge is not a good shotgun when compared to other shotguns. No, the Judge is not a long range tackdriver with .45 Colt either.
But let's be honest about what it can do, and do quite well.
5 yards is a lot more realistic in self defense scenarios than is 10 yards, and consider the facial damage with 3/4 ounce of off the shelf #4 shot. That amounts to over 100 pellets covering a 12-18" circle at 5 yards. Penetration ? Not the best, agreed, especially when trying to shoot through winter clothing.
But if we upgrade to 3" loads of 000 buck, now we're talking 5-.36" or 9.14mm lead balls, that add up to over 800 foot pounds of energy. Penetration ? You betcha, and at 5 yards it stays inside of a 8" circle. And we have only shot the first round. Fire the other 4, (and it can be done in under 2 seconds with a bit of practice) and that adds up to 25-9mm/38 cal holes that will for sure do some damage.
But where I think the Judge is underappreciated is if you can hand load .410 shells with either lead BB (32 or so .18"/4.57mm pellets) or even #2 lead shot (62 +/- .148"/3.76mm pellets) that still fit inside that 12" circle at 5 yards. Devastating does not adequately describe the effect.
Regarding .45 Colt performance, how does a 6" spread at 25 yards equate to poor performance in a defensive application, let alone when we again are honest about the typical 5-10 yard range with a 2" pattern ?
Quit trying to make the Judge into something Taurus never meant it to be, and quit bashing it until you try one out.
If you take the time to visit Taurus.com you'll find they really only designed The Judge for one purpose, and it performs that purpose quite effectively.
