Here in Florida, we just get a permit to carry. We don't disclose what weapons we have, or that we have any at all. Being former military I didn't even have to take the CCW course.
Word to the wise: Despite the carry laws being overbearing, you would be very ill advised to carry without a permit if in fact one is required where you live. If you ever get caught with it or, God forbid, you must use your weapon in self defense, you could wind up spending a long time in jail away from your loved ones.
Get the permit if you're going to carry. You can worry later about what to do in the highly unlikely scenario where door-to-door gun confiscation becomes reality.
Have you never met an immigrant to the USA from Cuba, the former USSR, or a Holocaust survivor?
Have you never lived in any foreign country?
The standard human scenario of corrupt political despotism is unfolding right before our very eyes in the USA, and some will still stubbornly refuse to “believe” it is happening, yet again.
Have a nice day!
