I have shot the Judge, and I would not recommend getting one for self defense. It is large, awkward, poorly balanced, and not very accurate with .45 Colt ammo. It's also awkward to carry in a holster. For those who live in an area where you see a lot of poisonous snakes near residences buildings, it would be a decent special purpose snake gun.
If you really want a Taurus self defense revolver, there are better choices than the Judge. IMO, one of their best choices is the stainless steel 7 shot, .357 mag Tracker with 4" barrel. Load it with Speer short barrel .357 ammo, and you have a lightweight, compact, well balanced, accurate, easy to shoot, handsome revolver that is easy to carry concealed in a holster. The ones I have fired have a good smooth trigger pull in double and single action. Only downside is the ported barrel makes it hard to clean if you shoot many lead bullets. Also, Speer warns that no handgun with a ported barrel (or comp) is safe to fire with any kind of shot shell ammo.
It's you money; get what you want. But IMO, you can do a lot better than the judge.
