If you want a shotgun, buy a shotgun. If you want a .45, buy a .45. As a compromise, the Judge fails at both.
The only valid argument I've seen in its favor, is that a load of birdshot directly in the face will strongly discourage a carjacker (or at least render him blind). Other than that, it sucks as a defensive weapon. It appeals to emotion, not logic.
The .410 shotgun is on the very low end of marginal when it comes to defensive use, and that's with an 18"+ barrel. Why do people project some magical qualities onto this same marginal caliber when it's delivered from a 2.5" handgun?
Muzzle energy is muzzle energy. Do the math, not the marketing hype.
