First gun in 50+ years and you’re worried about it getting stolen and used in a crime? The probability of that happening is pretty remote. Assuming you’re buying a pistol, buy a safe to store it as well. Never leave a gun unsecured and unattended. Know where it is at all times and you’ll be fine. There is USCCA insurance which is a good to have if you have to defend yourself.
Yes,it’s unlikely...but it is possible.And of course other bad things can happen with a gun. I could use it in self defense only to be sued by the heirs of the guy I shot. If I was required to reveal my ownership and didn’t the company might say “sorry,you’re on your own”.
