The New York legislation was signed by Gov. Andrew Cuomo on Tuedsay.
Among other things, It tightens a ban on assault-style rifles, calls for background checks on ammunition purchases, outlaws large-capacity magazines and tries to keep guns out of the hands of mentally ill people deemed to be a threat.
Supporters say it's a model for the nation while gun-rights activists are condemning it as a knee-jerk piece of legislation that won't make anyone safer and is too extreme to win support in the rest of the country.
