DENVER (KDVR) — Colorado is one of 16 states that have sued the Trump administration over its plan to allow the sale of forced-reset triggers that make semiautomatic rifles fire more rapidly and return devices already seized to their owners.
The suit announced Monday argues that returning the triggers would violate federal law, pose a threat to residents and law enforcement and worsen gun violence. It was filed in federal court in Maryland.

'It's hard enough for our local law enforcement officials to protect Colorado communities from gun violence without the federal government willfully ignoring the law,' said Attorney General Weiser. 'The law is clear: machine guns, and devices that turn a semiautomatic weapon into a machine gun, are illegal. We're suing to stop the ATF and the administration from making our communities more dangerous by distributing thousands of devices that turn firearms into weapons of war. These weapons have no place in our communities, and I will continue to fight to keep Coloradans safe from gun violence.'
The Colorado law banning the sale of rapid-fire conversion devices, including forced-reset triggers, was signed into law in April and will go into effect on Aug. 1, 2026. Second Amendment supporters have called on the U.S. Attorney General to investigate the measure as an infringement on the U.S. Constitution.
Weiser said in a release announcing the state's participation in the lawsuit that machine gun conversion devices like the forced-reset triggers are frequently used in violent crimes and mass shootings. The state attorney general said that by using these devices, firearms can exceed the rate of fire of many military machine guns.
'ATF has noted a significant rise in the use of these types of devices, leading to incidents of machine-gun fire increasing by 1,400% from 2019 through 2021,' Weiser said in a press release.
There had been several legal battles over the devices, which replace the typical trigger on an AR-15-style rifle. The Biden administration had previously argued the triggers qualify as machine guns under federal law because constant finger pressure on the triggers will keep a rifle firing, essentially creating an illegal machine gun. The ATF previously classified the triggers as machine guns, but under a directive from the Trump Administration, the bureau signed the settlement agreement that promises to stop enforcing federal law against the devices.

Rare Breed Triggers, the maker of the devices, had argued that the Bureau of Alcohol, Tobacco, Firearms and Explosives was wrong in its classification and ignored demands to stop selling the triggers before being sued by the Biden administration.
The Justice Department reached a deal announced last month with Rare Breed Triggers to allow the sale of forced-reset triggers. The company was previously represented by David Warrington, Trump's current White House counsel.
Under the settlement, Rare Breed Triggers agreed not to develop such devices to be used on handguns, according to the Justice Department. The settlement requires the ATF to return triggers that it had seized or that owners had voluntarily surrendered to the government.
The states' lawsuit is being led by the attorneys general of Delaware, Maryland and New Jersey. Other states involved are Colorado, Hawaii, Illinois, Maine, Massachusetts, Michigan, Minnesota, Nevada, Oregon, Rhode Island, Vermont, Washington, along with the District of Columbia. The attorneys general in those states are all Democrats, though the office in Hawaii is technically nonpartisan.
