What about the states where no conceal carry permit is required, i.e., Constitutional Carry?
In some of those States, citizens still get the permit so as to carry legally in less enlightened States which have a reciprocity agreement with their home State.
Example: West Virginia is a constitutional State. I still get the permit, so that I can legally carry concealed in Virginia, Kentucky, Pennsylvania, Ohio, and other reciprocal Shall Issue States. Maryland is hopeless.
If Trump and the republicans weren't such douche bags on guns, we would be demolishing the commies gun control arguments, incentivizing through grants and the tax code gun ownership and training, and fining and suing any public official, with personal liability, for any 2A infringements. The 13 states that have it right need to be copied elsewhere and Trump should make that a national priority.
But he wont.
