The state of California and the city of San Francisco have filed a lawsuit against two Florida companies that provide computer code and designs for making 3D-printed guns and ammunition magazines. The lawsuit alleges these products are enabling people to create untraceable 'ghost guns'.
Why it matters
The proliferation of 3D-printed ghost guns has become a major public safety concern, as these untraceable firearms can be easily obtained and used by criminals and other prohibited persons. This lawsuit aims to crack down on the distribution of the underlying code and designs that facilitate the creation of these ghost guns.
The details
The lawsuit targets Deterrence Dispensed and Polymer80, two Florida-based companies that sell computer-aided design (CAD) files and other technical information that can be used to 3D print firearms and magazines. The state and city allege these products violate California's laws prohibiting the manufacture of untraceable guns.
- The lawsuit was filed on February 10, 2026.
