2021 Colorado Code
Title 29 - Government - Local
Article 11.7 - Regulation of Firearms
§ 29-11.7-103. Local Regulations Governing Firearms Permitted

1. Unless otherwise expressly prohibited pursuant to state law, a local government may enact an ordinance, regulation, or other law governing or prohibiting the sale, purchase, transfer, or possession of a firearm, ammunition, or firearm component or accessory that a person may lawfully sell, purchase, transfer, or possess under state or federal law. The local ordinance, regulation, or other law may not impose a requirement on the sale, purchase, transfer, or possession of a firearm, ammunition, or firearm component or accessory that is less restrictive than state law, and any less restrictive ordinance, regulation, or other law enacted by a local government before the effective date of this section, as amended in 2021, is void and unenforceable. A local ordinance, regulation, or other law governing the sale, purchase, transfer, or possession of a firearm, ammunition, or firearm component or accessory may only impose a criminal penalty for a violation upon a person who knew or reasonably should have known that the person's conduct was prohibited.
2. Nothing in this section requires the Colorado bureau of investigation to consider anything other than state or federal law in its background approval process and determinations.
3. Nothing in this section authorizes a local government to restrict the manufacture or sale of items pursuant to a United States military or law enforcement procurement contract.
