...The answer is almost certainly, “No!”
The plaintiffs in this case, the Hansons, were legally permitted to purchase a firearm in both their home “state” of Washington DC and the state in which the FFL Mance conducted business, Texas. Had they been prohibited from purchasing a gun in either location this Court’s analysis would not apply. The Court addresses this issue in a lengthy footnote on page 22, in speaking to a concern raised by the Defendants that an FFL in one state may not be familiar with the gun laws of a different state, running the risk that the FFL would be selling a handgun to a resident of that other state who is prohibited under that state’s laws:
A Texas FFL must ensure that a Sacramento, California resident who purchases a rifle is legally entitled to do so under federal, Texas, California, and Sacramento law. Similarly, a non-Texas FFL must ensure that a Texas resident who purchase a rifle is legally entitled to do so under federal law and the laws of both states. While a California FFL in San Diego might have to research the local handgun restrictions in place for a Sacramento California resident purchaser, some 500 miles to the north, nothing prevents an out-of-state FFL from Reno, Nevada, from conducting the same research to ensure that a handgun transaction with a Sacramento resident, some 100 miles away, comports with federal, Nevada, California, and Sacramento restrictions. Under current law, an FFL is not authorized to transfer any firearm to anyone until the state or federal authority confirms the transfer is legally permitted under state and federal law. See 18 USC § 922(t).
As a practical matter, if it turned out that yesterday’s court order represented a way around the Massachusetts restrictions on transfers of restricted handguns, I am confident the legislature would promptly make whatever statutory changes were necessary to bring those restrictions back into effect—and, again, no FFL is going to risk being caught on the wrong side of a volatile set of gun laws for the pittance of a profit they make on a handgun sale.
