i have a question for those who know CA and CO law. My brother is a very big hiker and often hikes alone(yeah i know not that bright) he is wanting to buy a pistol for protection from wildlife mostly Mt. lions. My question is this he is currently in CA and wanting to buy one, but is a Washington state resident, what are the rules regarding him buying on as an out of state resident. Then also what are the laws for him to carry as an out of state resident in both CA and CO. Thanks
