Bill Overview
Analyzed Economic Effects
6 provisions identified: 0 benefits, 0 costs, 6 mixed.
Gun show organizers need insurance, security
Beginning January 1, 2026, organizers must send each local law enforcement agency with jurisdiction a security plan at least 14 days before each show. Plans must list vendors, expected attendance, security staff—including POST-certified officers—and entrances, exits, and cameras. Organizers must carry at least $1 million in liability coverage for qualifying attendee injuries through a Colorado-authorized or qualifying nonadmitted insurer. Every entrance and exit, including fire exits, needs guards or alarms. Video must cover event parking and the main entrance and exit throughout venue access, including setup and takedown; recordings must be kept for 6 months. Venue parking video can substitute if organizers keep it for 6 months. Unlawful management is a class 2 misdemeanor initially and a class 1 misdemeanor for later offenses; repeat convictions bring a five-year promoter ban.
Gun show sellers face licensing limits
Beginning January 1, 2026, vendors need a federal firearms license and a valid Colorado dealer permit. Their certification must include credential copies, promise compliance with listed firearm rules, and state they have no convictions for illegal firearm activity. Promoters must collect certifications at least 3 days before each show and keep them for 6 months afterward. Unlicensed people dealing with licensed vendors, including through consignment or help with private transfers, are excluded from vendor status—not other firearm laws. Unlawful vendor activity is a class 2 misdemeanor initially and a class 1 misdemeanor for later offenses; a second conviction bars vendor participation.
Minors need adults at gun shows
Beginning January 1, 2026, people under 18 must attend gun shows with a parent, grandparent, or guardian. Promoters may admit under-18 active-duty U.S. Armed Forces or Colorado National Guard members alone with valid military identification.
Gun show buyers face transfer checks
Beginning January 1, 2026, promoters must check and tag firearms brought in by anyone except vendors, security staff, or the promoter. The owner must sign the tag, which stays attached and states that private transfers require a licensed dealer. Transfers occurring wholly or partly on show grounds, including event parking, require dealer-run state background checks and approval, except for antiques, curios, and relics; dealers must keep required transfer records. Promoters must verify that buyers leaving with purchased firearms met the state’s three-day waiting period or qualify for an exception. Notices at every entrance and throughout the show must explain dealer background checks and legal storage requirements for firearms left in unattended vehicles.
Which gun shows face new rules
The law covers events with at least 25 firearms offered or publicly shown for sale, transfer, or exchange, or at least 3 firearm vendors. Covered grounds include event parking, but not adjacent street parking. Shows limited to antique firearms, curios, or relics are excluded. The rules apply to shows held on or after the law’s January 1, 2026 effective date. A qualifying referendum petition delays that date until official declaration of voter approval; voter rejection prevents the act from taking effect.
Gun vendors must secure firearm displays
Beginning January 1, 2026, vendors must prominently display their federal license and state permit. Firearms must stay unloaded and secured to a counter or wall with plastic ties or electronically monitored wire. Ammunition must require vendor help to access, and prohibited items include magazines over 15 rounds and unserialized frames or receivers. Each firearm buyer must receive written information on secure storage, unattended-vehicle storage, and reporting loss or theft within 5 days of discovery. Violations are class 2 misdemeanors initially and class 1 misdemeanors for repeat offenses, which also bar vendor participation.
