One of the best things about America is out Constitution and the Bill of Rights. These are our Country's founding documents, and guarantee us all certain Rights. Among those is the Right to bear arms. This means own guns. They have passed many laws that limit this Right, but yes, the short answer is that in America you are allowed to own guns.
Most of us on TFSF have many guns. We use them for sporting purposes and for self defense if necessary. I carry a little revolver every day, just in case I run into trouble. Never have so far, but it is nice to have it just in case.
