I see that the members interpreted the question in two different ways. I choose to respond to what I would do about the legality of having a 6 gun limit.
I was born and lived in Chicago, Illinois. The firearms restrictions were coming into play and I had one of the first FOID (firearms owner ID) cards. I left Chicago at 17 years of age and never returned. That's what I would do about your regulations..................find another place to live!
That kind of regulation would never happen in Texas. We wouldn't allow it here and there is a sizable group of Texas citizens who would vote to succeed from the US if the Federal government imposed that kind of restriction. I don't see that actually happening but it does illustrate the mindset here. We are free and will darned sure stay free. Any FED who thinks differently will have a huge surprise coming!
