The issue isnt the gun part of the law its the magazine capacity restriction section part of the law. Either way the law is F'd up and everyone including lawyers and the state itself does not know how to interpret it. This along with many other reasons is why it needs to go away, and go away now.
"The way the SAFE Act was structured, it edited multiple sections of the NY legal code in a way where one section didn’t necessarily apply to other sections. So while there was a specific exemption for pump action shotguns and other manual firearms in the “assault weapons” section, according to the lawyers I spoke to it didn’t apply to the magazine capacity restriction section"
