About 1,500 state gun bills have been introduced since the Newtown massacre.
178 passed at least one chamber of a state legislature. 109 have become law.
In the 12 months since the mass shooting at Sandy Hook Elementary School in Newtown, Conn., almost every state has enacted at least one new gun law. Nearly two-thirds of the new laws ease restrictions and expand the rights of gun owners. Most of those bills were approved in states controlled by Republicans. Those who support stricter regulations won some victories — mostly in states where the legislature and governorship are controlled by Democrats — to increase restrictions on gun use and ownership.Select categories from the table below to see all gun bills that passed at least one chamber of a state legislature.
