MS where I live is a Constitutional Carry State allowing both Concealed and Open Carry.
I still applied for and received a CCW so I can Carry in the other 30 or so Reciprocal States.
IMO the Unites States Congress is the only legislative entity that is allowed to regulate firearms in *any* way.And,of course,any legislation they pass is subject to scrutiny by Federal courts...sidestepping the thousands of petty little dictators in the states’ courts.
