The original .410 Judge is basically useless, as a .410 won't do much more than irritate most people. It's only use is killing small birds and snakes.

As for this gun, the ATF has determined it to be a short-barrelled shotgun and not a pistol, so it's not going to be sold.

Well, whatever floats his boat, I guess...

Another bit of hint: look at the keychain.
