ANNAPOLIS, Md. (AP) - Gov. Martin O'Malley has signed a comprehensive gun-control measure that supporters say makes Maryland's gun laws among the strictest in the nation.
O'Malley signed the bill on Thursday. One of the strongest provisions requires people to submit fingerprints to the state police to get a license to buy a handgun.
The measure also bans 45 types of assault weapons, but people who own them now will be able to keep them.
Gun magazines will be limited to 10 bullets.
The measure also bans gun ownership by people who have been involuntarily committed to a mental health facility.
The bill is scheduled to take effect Oct. 1. Opponents hope the law can be overturned in court.
