The state Assembly has approved a bill that would require Californians buying guns from out-of-state sources to go through the same steps required for in-state purchases.
AB1409 passed Wednesday on a 48-23, party-line vote and heads to the Senate.
The bill would require that firearms imported from other states be delivered to a California dealer. Under current state law, gun purchasers must wait 10 days, undergo a background check and have safety training.
Democratic Assemblyman Luis Alejo of Salinas says he is carrying the bill in response to mass killings, including the weekend slayings in Santa Barbara.
Republican Assemblywoman Shannon Grove of Bakersfield says Californians already must register guns purchased out-of-state.
The bill would take effect in 2015 if signed into law.
