The Cuomo proposal would appear to already have momentum with lawmakers in Albany, who start their 2020 session next Wednesday. Members of the state Legislature, under control of Democrats in both houses for the past year, were already talking in 2019 of additional measures needed to address sales of gun components, as well as other new gun control initiatives.

Cuomo has made gun control a policy priority since 2013 when he pushed through the SAFE Act; its provisions included an expanded ban on assault-style weapons, making it more difficult for guns to be purchased by individuals who are mentally ill and requiring private gun sales to be subject to background checks.

Last year was an especially busy one for gun-related measures in Albany. Cuomo and lawmakers jockeyed to press new gun laws onto the books; in the end, a series of approved bills included the 3D gun bill, additional weapon storage mandates for gun owners, additional restrictions on rapid-fire bump stock devices and extending the waiting period for gun purchases in certain instances. Last January, lawmakers quickly approved a measure – signed a month later by Cuomo – to allow family members, school administrators and law enforcement officials to seek a court order to confiscate guns possessed by people deemed to be an "extreme risk" to themselves or others.
