Semi-automatic gun ban nixed in Colorado’s Democratic-controlled statehouse after historic progress

Colorado’s Democratic-controlled Legislature has nixed a bill to ban the sale and transfer of semi-automatic firearms

A bill to ban the sale and transfer of semi-automatic firearms was nixed in Colorado’s Democratic-controlled Legislature on Tuesday as lawmakers pressed forward with a slew of other gun control bills on the 25th anniversary year of the Columbine High School massacre.

The western state has a deep history with firearms that is pockmarked by some of the most high-profile mass shootings nationwide. Both factors loom large over gun control debates in the Legislature, complicating attempts at such bans that nine other Democratic-controlled states have in place, including California and New York.

The Colorado House passed the ban in a historic first and what proponents see as a “tremendous achievement" after roughly the same proposal was swiftly nixed last year. But some Senate Democrats are wary of the efficacy and breadth of the ban, which prohibits the sale, transfer and manufacture of semi-automatic firearms.

Colorado’s blue shift is evident in part by a number of successful gun control measures passed last year, including raising the buying age for a gun from 18 to 21. Some half-dozen proposals are nearing passage this year, including a bill to put a measure on the November 2024 ballot to tax sales of guns and ammunition. Another would give the Colorado Bureau of Investigation more power to investigate gun sales that are already illegal.

The state’s purple roots have frustrated attempts at a broader ban.

A decade ago, two lawmakers were ousted in the state’s first recall elections over their support for bills that set limits on ammunition magazines and expanded background checks.

“That history, I think, lingers,” said Democratic state Sen. Julie Gonzales, one of the semi-automatic ban bill’s sponsors. She added that the proposal's success in the House “signals that there is a new space for us to have different conversations."

But for now, at a sparsely attended committee hearing Tuesday, Gonzales asked that the legislation be put to rest in the face of opposition from Senate Democrats.

On that committee sits Democratic state Sen. Tom Sullivan, who would have been a “no” vote, along with Republican lawmakers who have decried the bill as an encroachment on Second Amendment rights.

Sullivan’s son, Alex, was one of 12 killed in the 2012 Aurora theater shooting at a midnight screening of “The Dark Knight Rises.” The tragedy catapulted Sullivan into activism around gun control and then public office, where he has spearheaded many bills on the issue.

Sullivan said the weapons that the bill seeks to curtail are involved in only a small fraction of gun deaths and injuries. Those firearms include a long list of semi-automatic rifles, along with some pistols and shotguns, with certain characteristics, such as a threaded barrel or detachable stock.

Their prohibition wouldn’t make much of a dent in gun violence, Sullivan argued, and the proposal takes up immense political oxygen in the state capitol — energizing the opposition and detracting from more effective and less controversial gun control measures.

“The narrative is all wrong,” Sullivan said. “That’s what they want you to believe, that it’s assault weapons and schools. It’s not. ... It’s suicides and it’s domestic violence.”

Democratic state Rep. Tim Hernández, one of the bill's sponsors, said he'd had many discussions with Sullivan in the preceding months.

“We both agree that an assault weapons ban is not a silver bullet to the epidemic of gun violence,” Hernández said. “For us to get to a place where we are interrogating all the ways that gun violence shows up, we have to run policies for all the ways it manifests itself.”

The proposal is expected to be revived next year.

Meanwhile, other bills nearing the governor’s desk include a proposal to require more rigorous safety training for someone seeking a concealed carry permit. And one would require firearm dealers to obtain a state permit, not just a federal one, to give regulators greater power to enforce state gun laws.
