I have a push button lock unit (Simplex lock) and the main compartment holds the gun, along side is another smaller compartment just large enough for a mag. The top locking cover when opened allows access to the gun, it also at the same time allows the top of the smaller mag holder to open as well. It was sold to be mounted in a car and at that time since the gun was in a locked box, and the mag was in a different locked container, as long as the gun was not loaded, it was legal in Calif. I keep a copy of the dated receipt in it as a few months later it was not legal to be sold in Calif. I was wondering if this would be legal these days? And wonder if it has to be in the trunk, or would it be legal in the passenger area? They are both locked, and are not in the same container. Anyone know? Speaking mainly in Calif. but, other states which it would not be legal in?
