Not sure what they could have done in a state like NY but they did say and do this:
"This law does nothing but go after law-abiding gun owners, turning hundreds of thousands of New Yorkers into potential felons. Cuomo has attacked law-abiding citizens while failing to address violent crime or public safety. The NRA is providing significant support to the litigation by our state association, the New York Rifle and Pistol Association. NRA attorneys have also submitted an amicus brief in the lawsuit, challenging the constitutionality of this draconian law."
iirc the one case brought to court that nixed the seven round mag provision had nothing to do with the NRA
nothing in Connecticut either, so much for the power of the NRA
