While I do like vanity plates because they are about the only way to show a little personality without junking your vehicle up with bumper stickers, I certainly will not be letting everyone up and down the road know about my guns.
Yeah, all my extra money goes to reloading supplies, and I don't advertise, but...
My GF has TAC-IV on her plate, in honor of her Para Tac-Four.
When someone asks (depending who it is) she's been known to tell them that it stands for "Total Animal Count--4" which has an element of truth, as we have four dogs
The vanity plates are pretty cheap here in Missouri. I figure that most people will not even know what it means and if they do, they'll probably appreciate it. I am not worried about someone coming to take my guns. The fact that I have an NRA Life Member sticker on my truck and car probably tells them I have guns.
I will not put any advertisement of any kind on my car. Too much of an invitation to someone who doesn't share your opinion. If I had a plate like that on my car the next time I was pulled over would naturally be by an elitist cop with an axe to grind regarding the 2nd Amendment.
Around here though,the tag would get stolen and get your vehicle broken into because someone would want to steal the Sig 9mm they thought you left in the car.
I'm guessing for me to have "Hi-Point" wouldn't be as impressive.
I don't have a huge concern about break-ins or advertising, etc., but it does give me a slight pause of you putting your actual tag on the internet. Someone could ID you that way.
