The law, introduced by Gov. Martin O'Malley after the Newtown, Conn., shooting, drew headlines for banning the sale of assault weapons and limiting magazines to 10 bullets. But it also requires handgun purchasers to submit fingerprints and get a license. And it creates penalties for people who don't notify police when their firearms are lost or stolen. O'Malley, a Democrat, is scheduled to sign the bill Thursday morning.
