Let's just get it done. 1.) Must be 21 years old to buy ANY firearm. 2.) No gun sales except by registered dealers, and with standard paperwork filed with law enforcement, including any waiting time imposed depending on the local policy and laws. This should apply at gun shows too, same registration, same waiting period. Those with no license should not be allowed to sell firearms. It won't keep people younger than 21 from obtaining firearms, but it will make it harder than just walking into a store and plopping down their drivers license. Also I think there should be a nation wide single policy regarding wait periods, perhaps 10 days. I just don't see this as a hardship, requiring the buyer to wait 10 days to get their gun. A friend recently remarked that the waiting period should be waived for those who already own guns. I disagree. I think we should have one national firearm purchase policy that applies to all gun sales, and that the regulations should be applied equally and identically in all jurisdictions. Let's just make it simple. One law governs all firearm sales.
