It's happening, slowly but surely.
Oklahoma just became the 17th "constitutional carry" state, no permit required for law-abiding citizens to carry a gun, open or concealed!
Soon SCOTUS will take-up a good carry case, (Young v Hawaii would be a good one) and sane gun laws, that forbid states and local governments from banning the carry of guns for self defense, will be imposed across the USA, NO EXCEPTIONS!
Again, that is not true, currently the 9th Circuit is waiting on the New York case before going anywhere, and the original decision based on five southern states after the Civil War is too weak even for Trump's Court to uphold, don't hold your breath on that one
