The full accounting of who lobbied Colorado's failed 2026 gun bills is public for the first time. State lobbyist disclosure reports — the last of them due July 15 — close the books on a session in which all three of the legislature's marquee firearms-rights bills died in committee, and the completed record shows national gun-control groups and Front Range city halls lined up against the state's most prominent gun-rights lobby1234.
The three failed measures reached broadly. HB26-1072, sponsored by Rep. Scott Slaugh, would have codified an individual's right to own, possess, and use a firearm to the maximum extent permitted by the state and federal constitutions, and would have repealed extreme risk protection orders — the "red flag" mechanism that lets courts temporarily remove firearms from people found to pose a risk1. HB26-1021 would have repealed a wide slate of existing firearms laws in a single measure, among them private-transfer background checks, the minimum purchase age of 21, the three-day waiting period, safe-storage requirements, gun-free zones in government buildings, schools, and child care centers, and restrictions on unserialized firearms2. HB26-1212, sponsored by Reps. Ava Flanell and Carlos Barron, would have allowed permitless concealed carry at 18, made permits lifetime, and repealed local governments' authority to regulate carry3. All three now carry the legislature's "postponed indefinitely" status — the committee mechanism that kills a bill.
The red-flag repeal drew the heaviest organized attention. Rocky Mountain Gun Owners registered in support of HB26-1072 within days of the session's start; Everytown for Gun Safety Action Fund, the Brady Campaign to Prevent Gun Violence, COMBINE, and the City of Boulder all registered in opposition4.
The same filings map positions across the wider slate of 2026 firearms bills. Local governments lined up behind two regulatory measures: Boulder County, the City of Boulder, the City and County of Denver, and Blue Rising registered support for HB26-1144, a proposed ban on three-dimensional printing of firearms and components, with Rocky Mountain Gun Owners opposed; Boulder County, the City of Boulder, and the League of Women Voters of Colorado backed SB26-043, on record-keeping and regulation of firearm-barrel sales, with Douglas County opposed4. County Sheriffs of Colorado and the Colorado District Attorneys' Council registered as monitoring SB26-085, on military protection orders, and Colorado Ceasefire Legislative Action monitored HB26-1302, on the Colorado Bureau of Investigation's InstaCheck background-check unit operating hours4.
Most of the registered positions closed out June 30, per the filings, and the July 15 reporting deadline swept in the season's final disclosures — before then, the lobbying record of the 2026 gun fight was a running tally; now it is a complete one4.
