The Senate State, Veterans and Military Affairs Committee on Thursday approved the measure on a 3-2 party-line vote after a three-hour hearing.

The bill proposed by Sens. Chris Hansen, D-Denver, and Rhonda Fields, D-Aurora, would ban ghost guns in Colorado. For those who already possess ghost guns, the bill provides a compliance period through the end of 2023 to get the firearm serialized, which could be done by licensed firearm dealers.
