Majority (47) of states already have the local FFLs doing the background checks with the 4473. We are one of 3 states that require us to get a permit from the "state" first. And while I still hate waiting periods, I can't see why they just don't push BG checks out to the FFLs. But then I remember how stupid they are and how much they hate us.
I hate Giffords but it has a good summary. Most of their information is misleading for the uneducated. Take Nevada, they say that they don't require a Fed check, but that's not true. It's run through the State Police. Same check, different name.
SUMMARY OF STATE LAW
Twenty-two states and Washington DC have extended the background check requirement beyond federal law to at least some private sales.
Thirteen states (California, Colorado, Connecticut, Delaware, Nevada , New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Virginia, and Washington) and the District of Columbia require universal background checks at the point of sale for all sales and transfers of all classes of firearms, whether they are purchased from a licensed dealer or an unlicensed seller.
Two more states, Maryland and Pennsylvania, require point of sale background checks for handguns but not for long guns, like rifles and shotguns.
Instead of a point of sale background check, three states (Hawaii, Illinois, and Massachusetts) require all firearm purchasers to obtain a permit, issued after a background check, in order to buy any firearm. New Jersey requires firearm purchasers to both obtain a permit to purchase a firearm and, if the purchase is from an unlicensed seller, conduct the transaction through a federally-licensed firearms dealer. Four more states (Iowa, Michigan, Nebraska, and North Carolina) have this permit and background check requirement for the purchase of handguns, but not long guns. Illinois also requires a point of sale background check whenever a firearm is sold at a gun show.
