The roster is a gun ban, plain and simple. It places commonly owned arms beyond the reach of lawful gun owners in Massachusetts, including Glock handguns. Because Massachusetts law prohibits the sale of arms that are in common use, it conflicts with the Second Amendment’s text as interpreted by the Supreme Court. AdvertisementAs Dhillon notes, the district court held that, because Massachusetts' Approved Firearms Roster doesn't ban all handguns, it doesn't violate the right to keep and bear arms. If that's the standard, though, then Massachusetts could theoretically have an AFR with just one gun approved for sale.
