NY State, had the same kind of law starting in 2000 (not sure of this date); the outcome was the same. This article was from 2012
(2 yrs after the law had been passed):
--------------------------------------------------------------------------
With virtually no public notice or legislative debate, a centerpiece of ex-Gov. George Pataki's controversial multimillion-dollar anti-gun-crime program was shot dead Friday by Gov. Cuomo's new state budget.
The budget killed off the so-called CoBis, or Combined Ballistics Identification System, which was rolled out with much fanfare by Pataki in 2000 in what was widely seen as an attempt by the politically ambitious Republican "moderate'' to appeal to anti-gun Democrats nationally, possibly for a future presidential run.
Pataki claimed CoBis would use state-of-the-art technology to establish a "DNA database for handguns'' by requiring manufacturers of new semiautomatic pistols to file spent cartridge shells with the State Police, so that their markings could be kept in a traceable registry and compared to any found at crime scenes.
Trouble is, the Pataki program NEVER worked. Despite the hundreds of thousands of spent shells submitted, not one criminal was ever captured using the extensive and costly-to-maintain database, state officials concede.
"We are ending a program that doesn't solve crimes or make our streets safe,'' said Cuomo spokesman Josh Vlasto.
"That's what we said would happen from the start,'' crowed Tom King, president of the New York Rifle and Pistol Association and a National Rifle Association board member. "I think Andrew Cuomo is a very intelligent guy who didn't want to waste money, and this wasn't working."
Vlasto said CoBis cost about $1.2 million a year, but King said it was more like $40 million because of equipment, staff and related expenditures to get the system up and running.

In the end..... everything revolves around money and re-electability... Cuomo enacted severe gun control legislation (in 2012) in a state that already had severe gun control legislation; and he did it in an overnight legislative vote when 'nobody' was present in Albany....
