Thought about it a few years ago, but never saw the need. Not to mention, my friends getting harassed by having one when pulled over.
I have never been harassed. Simply show your DL and LTC and no problems at all.
My daughters and my wife all carry 9mm, I carry 40 or 45.
You fellas that carry .380s, my father in law did till he was attacked by a dog one night and unloaded on that dogs head. None penetrated till one went in his neck. The dog was a bull terrier.
He quit carrying the .380s after that.
