New York is extending the waiting period to buy guns from three days to 30 days to allow more time for background checks under a law approved Monday by Gov. Andrew Cuomo.

The pro-gun safety law is a response to a rash of shootings across the nation.

The bill originally passed both legislative houses in January.

It expands the time period for national instant background checks, currently set at three days, to 30 days.

Currently gun dealers perform background checks before making a sale, which typically takes three days before a recommendation is given.

Inspection results either recommend to proceed, deny or delay a sale — and if determinations recommend to delay, sellers must wait three days.

But supporters of the legislation argue that a three-day period is problematic as often the checks take longer than three days to process, after which point sales can be made before the delayed inspection is completed.

“For too long gun violence has plagued communities across our nation and while the federal government turns a blind eye, New York continues leading the way forward to protect our families and our children,” Cuomo said.

Cuomo also signed legislation banning the sale of bump stocks, devices that attach to automatic weapons and accelerate a shooter’s ability to fire — a measure that is already law on the federal level.

“By signing these measures into law we are strengthening our nation-leading gun laws — banning devices whose sole purpose is to create the most bloodshed in the shortest time frame and providing law enforcement the tools they need to stop firearms from falling into dangerous hands.”

“Common sense gun safety reform will save lives, period. Stronger background checks will keep guns away from dangerous people,” said state Senate Deputy Majority Leader Michael Gianaris (D-Queens), a sponsor of the safety background bill.
