 You know, it's legal in all 50 states. You don't need a permit. There's no background check. It's part of my self-defense strategy. I like the idea of having lethal and non-lethal options. If I can use a non-lethal option or no option, that's my first option. Anyway, no background checks needed. And by the way, you can check with Berna, but they will assure you that you can even, you know, pack it and check luggage, for example, if you're traveling.
