Ghost gun recoveries surged from 26 in 2015 to over 11,000 annually since 2021, fueling claims of a public safety crisis.

Action restricts law-abiding citizens’ ability to exercise self-manufacturing rights, echoing overreach seen under Biden-era policies now reversed federally.

Lawsuit Targets Online Gun Blueprints

California Attorney General Rob Bonta and San Francisco City Attorney David Chiu filed suit on February 6-7, 2026, in San Francisco Superior Court. Defendants Gatalog Foundation Inc., CTRLPEW LLC, Alexander Holladay, John Elik, and Matthew Larosiere face allegations of unlawfully distributing 3D-printable code for ghost guns, Glock switches, and large-capacity magazines. The complaint claims these files enable unlicensed individuals to bypass background checks. Investigators tested Glock-style handgun designs from the sites. This marks the first lawsuit specifically targeting digital code distribution, building on prior settlements with three ghost gun companies.

Ghost Gun Rise Sparks State Crackdown

Ghost gun recoveries in California jumped from 26 in 2015 to more than 11,000 annually since 2021. A 2024 incident involved a 14-year-old in Santa Rosa who manufactured multiple 3D-printed firearms. Plaintiffs cite these trends as a public safety crisis, arguing unserialized guns arm minors, felons, and abusers. Effective January 1, 2026, a new state law prohibits promotion or facilitation of illegal firearm manufacturing. Bonta and Chiu seek a court injunction to halt California access to over 150 designs. Defendants, Florida-based, have not commented as of February 9 publications.

Stakeholders Clash Over Second Amendment Implications

Rob Bonta leads the suit to protect communities from untraceable weapons and position California as a national model. David Chiu emphasizes local dangers, noting blueprints make guns quick and cheap for anyone, including teens. GIFFORDS Law Center’s Adam Skaggs praises the action against industry shifts to 3D code. On the other side, defendant Matthew Larosiere, a gun rights attorney, previously described ghost guns as a legal hobby in 2019. This dynamic pits state enforcers against online facilitators, raising concerns for hobbyists and self-defense advocates nationwide.

Potential Precedent Challenges Home Manufacturing

Short-term, an injunction could block California users from these platforms, testing the 2026 law’s reach. Long-term, success may inspire lawsuits against digital distributors elsewhere, strengthening gun control models despite President Trump’s federal reversals of Biden overreach. Affected communities include urban areas like San Francisco and Santa Rosa with high recoveries. Pro-Second Amendment citizens face restrictions on home fabrication, a practice rooted in individual liberty. Politically, the move advances state-level controls amid national shifts toward border security and reduced federal gun restrictions.

Broader effects target online file-sharing platforms evading regulations. Socially, fewer crime guns may result, but at the cost of limiting traditional American ingenuity in self-reliance. With President Trump restoring constitutional priorities, California’s actions highlight persistent blue-state resistance to limited government. Law-abiding citizens risk criminalization for lawful hobbies, underscoring the need for vigilance against erosion of gun rights.
