Welcome to the forum from northern Illinois Kim9, I'm sorry to hear that because of California's laws Kimber can't service your gun. Can a gunsmith in California legally service it? I know that Kimber doesn't like to sell much in the way of gun parts to the public but maybe they will sell the needed parts to a local gunsmith considering the circumstances.
