Identification Requirements

Colorado requires a background check for almost all firearm transfers between private parties which would include proof of identification.

The waiting period does not apply to the sale of an antique firearm or a curio or relic; the sale of a firearm by a person serving in the armed forces who will be deployed outside of the United States within the next 30 days to any family member; or a firearm transfer for which a background check is not required pursuant to state or federal law.

Age Requirements in Colorado

Age requirements

According to CRS 18-12-108.5, a person between the age of 18-20 may legally possess a handgun and one could be transferred to them as a bona fide gift from an immediate family member.

As of August 7, 2023, the minimum age to purchase a firearm in Colorado is 21 years old. A new law, Senate Bill 169, also makes it illegal to sell a gun to anyone under 21.
