I am always amazed at the naivete of some fairly intelligent folks.
Here we are in the midst of the greatest fight in the history of the nation to preserve our Second Amendment Rights, with a President, Congress, most governors and state legislatures, the courts, the national media, and the UN all pushing to eliminate our right to own and use firearms, and some devoted firearm folks cannot see where this is headed.
It is possible that guns will become cheap, but if so it will only be because the government has banned the manufacture and selling of most types of ammunition.
