Advocates of stricter restrictions on gun ownership believe they can notch new wins in state legislatures across the country this year.

Advocates pointed to Massachusetts and New Jersey, the first two states to ban so-called bump stocks. Both bills were passed by Democratic legislatures and signed by Republican governors.

Bump-stock ban bills have been introduced in Pennsylvania, South Carolina, Indiana and Washington.

“States are really taking the lead on banning these weapons in the face of congressional inaction,” said Robin Lloyd, director of government affairs at the Giffords Law Center to Prevent Gun Violence. “There is a growing acknowledgement and recognition that we have a gun safety problem in this country, and there are common-sense solutions.”

Legislators in several states have also advanced measures that would prohibit those who pose a risk to themselves or others from possessing a firearm.

One version of those prohibitions would allow family members or law enforcement to petition for extreme risk protection orders, temporarily barring someone who poses a threat. Those measures have passed in California, Washington and Oregon.

Massachusetts lawmakers have heard testimony on an extreme risk protection order bill, and New York legislators rolled out their version on Wednesday. New Jersey and Delaware are also likely to take action on their versions this year.
