Not surprised, either that Moonbeam signed the law or that he waited until the last day to do so.
It puts CA's "may issue" into a different light versus Heller/McDonald, as at least one justification for the caprice and unequal treatment has been that open carry was an alternative for self-defense when a sheriff or chief was clearly using his "may carry" authority to prevent concealed carry or limit it to friends and the "right people".
Moonbeam may have made a mistake. We'll have to see.
Loyalty to petrified opinions never yet broke a chain or freed a human soul in this world — and never will.
— Mark Twain
