I understand the intent, but feel that there are so many other loopholes that put much worse weapons on the street than a printer. Besides, my prints can barely sustain normal use, much less a bullet being fired from them. I would think that this is more of a risk to the person holding the gun than who it’s pointing at.
A big part of the increase in “ghost guns” is that New York’s definition of “ghost gun” includes not only the scratch made guns that most people think of as “ghost guns” but also any gun without an easily read serial number. So regular guns with obliterated serial numbers count as “ghost guns” in New York.
