New Jersey’s already strict firearm laws got even tougher Tuesday as Gov. Phil Murphy signed four new gun control bills into law — including one designed to make personalized “smart guns” more easily available in the state.

It comes a little more than a year after Murphy signed six firearm laws, vowing to make New Jersey a national leader in “common-sense” gun safety. The Democratic governor has championed the latest laws as his “Gun Safety Package 2.0.”

“Even though there’s more to do, we must take great pride in what we are doing today,” Murphy said at a signing ceremony at Governor Livingston High School in Berkeley Heights. “These new laws will send the message we take gun safety and the safety of our communities seriously.

The laws expand the list of crimes that bar someone from owning a gun in New Jersey, attempt to curtail gun trafficking from other states, and aim to prevent suicides.
