TRENTON -- State lawmakers on Monday will take up three measures aiming to tighten New Jersey's gun control laws -- voting at a time when the debate over firearms in the U.S. has once again grown tense.

Here's what's on the agenda:

DOMESTIC VIOLENCE BILL

In one vote, both the state Senate and Assembly will decide whether to override Gov. Chris Christie's veto of a bill to force those convicted of domestic violence in New Jersey to surrender their guns and their permits to buy new ones.

The legislation (S805/A1211), which initially passed with broad bipartisan support, would create a formal process to remove firearms from the hands of domestic abusers in the state, both in cases where a restraining order was in effect and upon conviction of a domestic violence offense. Christie, a Republican, vetoed it in May.

'SMART GUNS'

In another vote, the state Assembly will decide whether to give final legislative approval to a bill designed to encourage development of personalized handguns, or "smart guns."

The state Senate passed the measure (S816/A1426) in February.

The bill would loosen an existing New Jersey law that is said to have actually stifled production of smart guns.

CARRY PERMIT REGULATIONS

In the third vote, the state Senate will decide whether to give final legislative approval to a bill that would more strictly define the "justifiable need" New Jerseyans must show in order to obtain a permit to carry a handgun in the state.

The state Assembly passed the measure (S2165/A3689) two weeks ago.

Monday's vote comes after both houses gave final approval to a resolution to block changes the Christie administration unveiled to make it easier for residents to obtain a concealed carry permit.

Second Amendment advocates have argued for years that New Jersey's permitting process makes it nearly impossible for anyone who isn't a retired law enforcement officer to get such a permit.

THE DEBATE INTENSIFIES

The call for more gun control reform has intensified across the country since a gunman killed 49 people and wounded 53 others at a gay night club in Orlando, Fla. -- the worst shooting in American history. Authorities say the shooter had declared allegiance to terrorist group the Islamic State.

Democrats in Congress even staged a 25-hour sit-in to lobby for votes on legislation to prevent people on the terrorist watch list from buying weapons and to expand background checks to purchases at gun shows and over the Internet.

But Second Amendment supporters say more gun control will do little to stop criminals and terrorists from obtaining guns, while restricting the rights of law-abiding citizens.

Christie also accused Democrats of "exploiting" the Orlando massacre by pushing for more laws.
