I am NOT confident that SCOTUS would rule correctly and, if we lose in a 5-4 ruling with a ghastly anti-carry opinion written by Roberts, then those states' concealed carry protections MAY be in jeopardy.
I feel for my brethren Deplorables in blue "may issue" states. But I would rather suffer the sporadic injustices of "may issue" statism when there ARE many surrounding states that permit freedom, than gamble and lose at the federal/SCOTUS level level unless we get two liberal retirements and good replacements.
But those few states contain about half of the nation's population.
