My cali king only eats fingers when he is super hungry. I didn't handle him for about a 2 year span a few years ago and I was still able to handle him without a problem.
If your snake is a cali king, to me it sounds like it's still hungry. Especially if it's striking and coiling. These snakes can be pigs, mine would eat 7-9 decent sized pinkies or 5-7 fuzzies in one sitting on a 7-10 day schedule when it was a young. You may be feeding it generously, I would try an added prey item or 2 and/or increase how often you feed it.
