CO Dems Advance Bill to Prohibit 3D Printing of Ghost Guns

Legislation would strengthen Colorado’s law to crack down on ghost guns


DENVER, CO - The House today advanced legislation on a preliminary vote to prevent gun violence by prohibiting the three-dimensional printing of firearms, large-capacity magazines or other firearm components.


“Three-dimensional printing technology has become much more accessible in recent years, which has been taken advantage of by bad actors who print firearms and firearm parts to avoid background checks and other gun violence prevention laws,” said Rep. Lindsay Gilchrist, D-Denver. “3D printed guns and gun components are an increasing threat in our communities because they lack identification that law enforcement can use to track the weapon back to a suspect, and they undermine life-saving guardrails like background checks and waiting periods. Our legislation would crack down on this illegal practice to protect our communities from gun violence and save lives.”


“We’re being responsive to new technology that threatens the safety of our communities by bringing legislation to ensure that everyone must adhere to Colorado’s laws before they can access a firearm,” said Speaker Pro Tempore Andy Boesenecker, D-Fort Collins. “I proudly passed Colorado’s ghost gun ban in 2023, which helped prevent unserialized guns and gun parts from terrorizing our communities. This legislation strengthens our 2023 law to keep ghost guns out of the hands of dangerous individuals and protect Coloradans from gun violence.”


HB26-1144 would prohibit the use of a three-dimensional printer, or similar devices, to make a firearm or a firearm component. An initial violation of this provision would be a class 1 misdemeanor, and any subsequent violation would be a class 5 felony. The bill would also prohibit the sale or distribution of instructions on how to use a three-dimensional printer to create a firearm or a firearm component. A violation of this provision would be a civil infraction. This does not apply to the three-dimensional printing of non-functional or prop firearms.


Since 2016, the number of ghost guns used in crimes throughout the country increased by 1000-percent, yet over 99-percent of those guns cannot be traced back to a user, owner or producer. Between 2016 and 2021, law enforcement reported recovering over 45,000 privately-made firearms, including in nearly 700 homicide or attempted homicide investigations. When an untraceable gun is used in a crime, it can be impossible for a gun violence victim and their family to seek accountability.


Speaker Pro Tem Boesenecker passed the original “ghost guns” law back in 2023, which prohibited the possession, sale or transfer of unserialized firearms, frames and receivers.
