That’s why you need a cheap one to give up and the good stuff stored in a secure location.
DING! Winnner!!! Always have one "throw-away" registered gun so when they come to take away your arms, they can only take what they KNOW about.
Not sure if other states register guns, Illinois does. I have two (that they know about.) They can have 'em, without a fight. The rest that I purchased out of state and brought home with me are the ones I'm interested in keeping.
My dad's cousin in Norway was a teenager in the resistance against the Nazi's. As an adult he was a successful business man and owned hunting property and a big outdoors-man. Officially he only owned one gun. A single-shot shotgun. Some lessons are learned the hard way.
