HB1238 revises Colorado law governing gun shows and gun show vendors. The bill defines gun shows more broadly, excludes gun collectors shows focused only on curios, relics, and antique firearms, and establishes a new regulatory framework for promoters and vendors. It requires promoters to prepare and submit a security plan to local law enforcement, carry at least $1 million in liability insurance, maintain video surveillance of entrances, exits, and parking areas, control firearm check-in/tagging at the door, restrict unsupervised entry by minors, verify waiting-period compliance for firearm purchasers leaving the show, and post notices about background checks and safe storage. It also requires vendors to be federally licensed and hold a Colorado state firearms dealer permit, certify compliance before participating, and follow rules on firearm display, storage, and written disclosures to buyers.
The bill also strengthens background-check requirements at gun shows by requiring licensed gun dealers on-site to process transfers, mandating that any firearm transaction occurring at the show go through a background check, and requiring dealers to keep records as if the transaction occurred at retail. It expressly exempts antique firearms and curios or relics from the background-check section. The bill updates related statutes to align with the new gun show definition and to clarify that dealers may conduct gun-show sales outside normal business hours. The act takes effect January 1, 2026, and applies to gun shows held on or after that date, subject to referendum.
The bill’s impact on state law is substantial: it replaces the prior gun-show provisions in Title 18 with a more detailed regulatory scheme and adds criminal penalties for noncompliance. Promoters and vendors can be charged with misdemeanors for violating the new requirements, and repeat violations can lead to higher misdemeanor penalties and, for promoters, a five-year ban from acting as a gun show promoter. The bill also affects law enforcement notification, dealer recordkeeping, and the handling of firearms, magazines, and serialized/unserialized components at gun shows.
Overall sentiment in the recorded votes appears mixed but ultimately favorable in both chambers, with the bill advancing despite several close and failed amendment votes. It passed the House and Senate on third reading and the House later concurred in Senate amendments. The pattern of votes suggests significant support for tighter gun-show regulation, but also meaningful opposition, especially during committee-of-the-whole amendment votes and final passage in the House and Senate.
The main points of contention are the scope and burden of the new requirements. Supporters frame the bill as a public-safety measure aimed at reducing illegal firearm transfers, trafficking, and gun violence through stronger oversight, background checks, and security standards. Opponents appear to have focused on the practical and legal burdens on promoters and vendors, including insurance costs, surveillance requirements, mandatory dealer participation, restrictions on minors, and the treatment of private-party transfers and prohibited items such as large-capacity magazines and unserialized firearms. The bill also reflects tension between statewide regulation and local control, as it requires compliance with local laws and law-enforcement coordination while declaring gun-show regulation a matter of statewide and local concern.
The bill repeals and reenacts Colorado’s gun-show statutes in Title 18, creating new definitions and compliance obligations for gun show promoters, vendors, and licensed gun dealers. It imposes security planning, insurance, surveillance, notice-posting, vendor certification, background-check, and recordkeeping requirements, and it creates misdemeanor offenses for violations. It also amends related statutes to conform to the new gun-show framework and clarifies that certain dealer sales may occur at gun shows outside normal business hours.
The bill appears to have drawn strong support from lawmakers who favor tighter gun-show regulation, but it also faced notable resistance, as shown by several failed amendment votes and close roll calls. It ultimately passed both chambers and the House concurred in Senate amendments, indicating enough support for enactment despite controversy. The recorded votes suggest the measure was politically divisive rather than broadly unanimous.
The biggest disputes center on whether the bill’s requirements are necessary public-safety measures or overly burdensome regulations on lawful gun commerce. Supporters emphasize background checks, security plans, insurance, and controls on trafficking, large-capacity magazines, and unserialized firearms. Opponents are likely to object to the cost and operational complexity for promoters and vendors, the mandatory use of licensed dealers for transfers, the surveillance and tagging requirements, and the restrictions on minors and certain firearm types. The bill also raises concerns about how far the state can go in regulating gun shows as a matter of statewide concern versus local or private commercial activity.
