It’s not explicitly enumerated more than anything else we’re talking about. It’s always up to interpretation. Does the constitution say where to draw line between me bearing a knife and a nuke? Nope, ‘arms’ is defined conveniently in the eyes of whoever’s in power when this is decided. That’s how all of this works!
All states with "shall issue" are still in effect because its a straight here are the requirements, if you meet them and are not a prohibited person, you get your permit.
Also, the right to bear arms is explicitly enumerated in the constitution, so taking that right away isn't up to the states. The right to an abortion is not. So it goes to each state to decide.
