Only the Taurus haters think it's a bad idea .
I don't hate Taurus, I own and love one of their firearms and it has given me no reason to not like Taurus products.
That being said, I just have an aversion to polymer framed revolvers. I think they look like toys. It is a cheaper gun, and that is all it really proves. I am not sure about the polymer judge, but their other polymer guns seem about the exact weight of their metal framed revolvers.
I don't dislike the standard judge, just the plastic judge. Kept loaded with 000 buckshot, home, car, personal defense ranges it will kill a threat. You, me and everyone else either likes it or they don't, but I bet a whole lot of people are going to hate the polymer judge because it looks like a toy.
