I have to disagree here, sorry Zinc. I have had plenty of success with Kings and regular handling. My boy comes out almost daily with the obvious feeding/shed exceptions. Have I been tagged? Yes. But it was MY fault. I spooked him and my hand was right next to his face. not his fault.
Prior to getting back into keeping snakes this time, I used to have Kings and my buddy/neighbor did as well, all sweethearts handled regularly.
I've also known a few other Kings who were great when handled. In fact, I have only handled one that I would consider nippy besides a few juveniles who settled down very quickly. The nippy girl was in the store when I bought Django and I handled her for about 5 minutes and was tagged about 5 times (she only held on once for a few seconds and barely drew blood.). Needless to say, she wasn't coming home with me.
This is one of the reasons I personally like to meet an animal (any animal) before taking it home.
