Gov. Andrew M. Cuomo on Tuesday announced a series of actions his office says are “to prevent the distribution of dangerous 3D gun plans that allow individuals to cheaply create functioning and untraceable firearms, including weapons that are illegal in New York State.”

First, the governor’s office said he issued a cease and desist letter to Defense Distributed to block the distribution of plans for 3D guns in New York state after the Trump administration allowed unchecked distribution of the plans.

Second, the governor’s office said he directed state police to issue a notice reminding New Yorkers that manufacturing assault weapons—including with 3D printers—is illegal in New York.

Third, the Cuomo’s office said he announced the he would pursue legislation “to bolster the state's nation-leading gun safety laws and outlaw private production of all 3D and so-called ghost guns that are untraceable and invisible to metal detectors.”

"While the Trump administration tries to put more guns in the hands of criminals and dangerous individuals, New York is taking action to uphold our laws and keep our communities safe," Cuomo said in a prepared statement. "As the nation rises up and calls for action against gun violence, it is absurd and frightening that the federal government wants to make accessing an automatic weapon as easy as hitting print. New York is proud to have the strongest gun safety laws in the nation, and we won't let this federal government take us backwards."

The Trump administration reached a settlement with Defense Distributed in June allowing the organization to publish plans, files and 3-D drawings of guns beginning Aug. 1 that can be used to create functioning weapons. The settlement reversed the position of the previous federal administration, which banned the distribution of such content, Cuomo’s office said.

Cuomo issued a cease and desist letter to Defense Distributed, threatening legal action if the organization makes it available in New York. The Governor is demanding that the organization restrict accessibility of its site in New York to prevent New York residents from obtaining the files, according to the governor’s office.

New York has also joined other states to sue the Trump administration for reversing course and creating this significant public safety risk.

Governor Cuomo also directed state police Superintendent George P. Beach II to issue a notice reminding New Yorkers that it is illegal in New York for a person who is not a licensed gunsmith to manufacture assault weapons, including with 3D printers. Additionally, the possession of an assault weapon is a separate felony under New York state law pursuant to the NY SAFE Act, Cuomo’s office said.

“Moreover, the production of pistols and revolvers is also illegal in the absence of a license to own one. Even a valid pistol permit does not in and of itself authorize an individual to possess a 3D-printed pistol or revolver, since there is no guarantee that a local firearms licensing officer will allow a 3D-printed pistol or revolver to be registered on a pistol license,” according to Cuomo’s office.
