Colorado's legislature is taking aim at the growing threat of 3D-printed firearms and loosely regulated gun barrel sales, advancing a pair of gun control bills through both chambers.

The Denver Post reported that lawmakers moved closer to banning 3D-printed firearms and more tightly regulating the sale of gun barrels during a Monday morning vote.

The legislation targets what gun safety advocates describe as emerging loopholes in existing firearms regulations. 3D printing technology has raised new concerns about the ability to manufacture firearms without traditional regulatory oversight or background checks. Meanwhile, gun barrels—key components of firearms—have historically been subject to less regulation than complete weapons.

These bills represent part of a broader national effort by states to adapt gun regulations to technological advances. Supporters argue that 3D-printed firearm production circumvents existing safety measures and background check requirements designed to keep weapons out of the hands of prohibited purchasers.

The measures have advanced through both the Colorado House and Senate, suggesting bipartisan or at least sufficient support to move forward in the legislative process. However, details about specific provisions and any amendments made during deliberation were not immediately available.

The legislation reflects ongoing efforts by Colorado to address gun violence through regulatory measures. The bills join other state-level proposals nationwide that attempt to keep pace with evolving firearms manufacturing technology.
