ALBANY, N.Y. -- "The universal background check, that's one of the big holes in the system now," said Schenectady Mayor Gary McCarthy.

And one this coalition of mayors wants to see closed nationwide, with comprehensive federal gun control legislation similar to the law passed in New York.

"The federal government, as they've always done, need to follow what's happening in the Empire State," Jamestown Mayor Sam Teresi said.

Governor Andrew Cuomo signed the New York SAFE Act last month, banning military style weapons and high ammunition magazines. The mayors say more relaxed rules in other states make it easier for criminals to circumvent the law.

McCarthy said, "They go to those states, they acquire those weapons and they end up in our cities here in New York State and in other urban areas throughout the country."

But as the mayors urge congressional leaders to act, legal challenges to New York's new law are already mounting.

"The suit that we're filing against the law is going to be telling to see what exactly happens," said Tom King of the New York State Rifle and Pistol Association.

King says he's expects that suit and the Second Amendment issues it will raise to make it to the Supreme Court and he expects that leaders in Washington will be watching.

"I think that there are some cooler heads in Congress who are going to take a more in depth look at this and I don't think you're going to see anything that's near what the New York SAFE Law was," King said.
