I'm still new to this Forum, so I'm not sure if this question has come up before or not.

My wife & I used to travel extensively on vacation, via automobile. We are both in our 70s now & still like to explore the USA, but fly instead of drive.

I would like to start taking a small handgun with us for self-defense.
Any thoughts, suggestions or advice, regarding TSA procedures would be appreciated, from those who have done this before.
Thanks in advance.
