The Department of Justice filed a federal lawsuit against California on Wednesday, moving to strike down the state's ban on Glock handguns just hours after the restriction took effect. The suit marks the sharpest confrontation yet between the Trump administration and Sacramento over firearms regulation, and it arrived exactly when DOJ officials said it would.
Acting Attorney General Todd Blanche and Assistant Attorney General for Civil Rights Harmeet Dhillon announced the action on July 1, 2026, the same day California Penal Code 27595 went into force. The law bars dealers from selling certain semiautomatic pistols the state has classified as "machinegun-convertible pistol[s]", a category that sweeps in Glock handguns, which Blanche called "the most popular type of handgun in America."
The DOJ had warned California this was coming. Dhillon sent a formal letter to Gov. Gavin Newsom and California Attorney General Rob Bonta before the effective date, demanding the state halt enforcement and enter pre-suit negotiations. Fox News reported that Dhillon gave state officials until 5 p.m. on the Tuesday before the filing deadline to agree to talks and acknowledge the law's unconstitutionality. California let the clock run out.
Blanche framed the suit in unambiguous terms, as Breitbart News reported:
"The Second Amendment is a sacred right belonging to all Americans, even those in California. California cannot ban the most popular type of handgun in America. We will work to stop this blatant trampling of our rights by the California government to protect the rights of lawful gun owners."
Dhillon, who heads the DOJ's Civil Rights Division, the unit that filed the complaint, was equally direct:
"The Civil Rights Division will defend law-abiding citizens from states that seek to disarm them illegally. This lawsuit is yet another example of this Justice Department enforcing the Second Amendment by protecting citizens against unconstitutional state regulation of firearms."
The DOJ's argument is straightforward: California cannot reclassify one of the most widely owned handgun platforms in the country as a machine-gun component and then ban it from sale. The Civil Rights Division is treating the matter as a constitutional-rights enforcement action, not merely a policy dispute.
The law traces back to Assembly Bill 1127, which California Democrats pushed through the legislature in 2025. Newsom signed the measure on October 10, 2025. Sponsors sold it as a response to the criminal use of "Glock switches", small, illegal devices that convert semiautomatic pistols to fire in fully automatic mode. Those switches are already prohibited under federal law.
But the legislation went far beyond switches. By labeling standard Glock pistols as "machinegun-convertible," California lawmakers effectively banned the sale of the handguns themselves. The distinction matters. Criminalizing a device that is already federally banned is one thing. Prohibiting dealers from selling a lawful, factory-standard handgun to law-abiding buyers is something else entirely.
Dhillon appeared to anticipate this argument in her earlier warning to state officials. Fox News reported that she told Newsom and Bonta that Californians "should not be forced to settle for decade-old models of handguns to ensure that they remain safe inside or outside the home."
A spokesperson for Newsom pushed back before the suit was filed, telling reporters: "This is fake news. There is no Glock ban." That claim is difficult to square with the text of a law that bars dealers from selling pistols the state itself categorized as machinegun-convertible, a label that captures Glock models by design.
Just The News reported that the DOJ's complaint also takes aim at California's Handgun Roster, a longstanding regulatory mechanism that has effectively prevented new handgun models from being sold in the state since 2013. The roster requires manufacturers to meet a set of technical requirements, including microstamping technology that no major manufacturer has adopted, before a pistol can be approved for retail sale in California.
The practical result: Californians have been locked into purchasing handguns from a shrinking, outdated list for more than a decade. By challenging both the Glock ban and the roster in a single action, the DOJ is mounting a broad Second Amendment offensive against Sacramento's firearms regime.
Newsom, already facing a separate DOJ investigation into his personal and political conduct, now finds himself defending his gun-control agenda in federal court at the same time.
The Glock ban suit landed alongside a parallel DOJ action against Virginia. The Associated Press reported that the department sued Virginia's Democratic Gov. Abigail Spanberger on the same day her state's ban on the sale and manufacture of certain semiautomatic firearms took effect. Blanche tied the two cases together with a single principle: "The Constitution is not a suggestion, and the Second Amendment is not a second-class right."
Spanberger's office defended the Virginia law, stating the governor believes "firearms designed to inflict maximum casualties do not belong in our communities, near our kids and schools, or on Virginia's streets." Both states' attorneys general have signaled they intend to fight.
The twin filings signal a deliberate strategy. The Trump DOJ is not picking off isolated local ordinances. It is confronting blue-state firearms restrictions head-on, using the Civil Rights Division as its enforcement arm, a choice that reframes gun rights as a civil-rights matter, not merely a regulatory disagreement.
Newsmax noted that the California suit challenges both the new Glock restrictions and the state's Handgun Roster, while the Virginia suit targets a ban on certain semiautomatic rifles, including AR-15-style firearms. Together, the cases cover handguns and long guns, a comprehensive challenge to the two most common categories of Democrat-backed firearms bans.
The lawsuit adds another front to the growing legal and political confrontation between the federal government and California's Democratic leadership. The DOJ has already opened investigations touching California governance, including federal election fraud probes in the state and scrutiny of officials at multiple levels.
Newsom, widely seen as positioning himself for a 2028 presidential bid, has responded to the pressure by casting himself as a defender of California values against federal overreach. But the Glock ban presents a particular problem for that narrative. The governor's own spokesperson denied the ban exists, an odd posture for an administration that signed the legislation and let it take effect on schedule.
Meanwhile, California Republicans have demanded their own investigations into Newsom's conduct, creating additional pressure from within the state. The governor is fighting on multiple fronts simultaneously, and the Glock ban suit ensures the Second Amendment will be one of them.
Several questions remain unanswered. The DOJ has not disclosed the specific court or district in which the complaint was filed, nor has it released a case number. It is unclear whether the department is seeking emergency injunctive relief, a temporary restraining order or preliminary injunction, to block enforcement while the case proceeds. If it does, the timeline could move fast.
Neither Newsom nor Bonta has issued a formal public response to the filing itself, as distinct from the pre-suit posturing. How aggressively California chooses to defend the law, and whether the state attempts to enforce it while litigation is pending, will shape the next chapter.
The DOJ warned Sacramento exactly what would happen. Sacramento ignored the warning. Now the suit is filed, and California's leaders will have to defend a law that bans one of the most common handguns in America by calling it a machine gun.
Good luck with that in front of a federal judge.
