But a number of states have come up with their own exceptions to that rule. Alabama does not allow a non resident of Florida with a nonresident FL permit to carry in their state. If you live in FL with their CCW permit, you're fine. But if you live in MN and have a FL permit, forget carrying in Alabama. Same for others. Better check.
I’ve carried whatever I want, where ever and whenever I wanted, for the past 40 years, across multiple state boundaries while traveling between duty stations. The Constitution I swore an oath to uphold and defend was my guide. I don’t have to check jack shit.
