LOS ANGELES (AP) — A federal judge on Monday blocked key provisions of a California law that drastically restricts the sale of new handguns in the state, saying parts of the legislation violate the Second Amendment. In California, state law requires new handguns to have three components: A chamber load indicator, which shows whether the gun is loaded; a magazine disconnect mechanism that will stop the gun from firing if the magazine is not properly inserted; and microstamping capability so law enforcement can more easily link spent shell casings to the guns they were fired from. “For too long, the Second Amendment has been significantly infringed upon by elected officials who have taken every opportunity to put roadblocks in front of law-abiding citizens seeking to exercise their Second Amendment rights,” said Lawrence Keane, the organization’s senior vice president
