Privately Selling a Firearm

Anyone can privately sell a firearm in the state, but if the private owner does not have a proper license to sell, they must utilize a licensed gun dealer to run a proper background check on the buyer.[1]

Prohibited from Buying

Under Colorado state law,[2] an individual is not permitted to purchase or own a firearm in Colorado if that person:

  • Has been arrested for or charged with a crime for which the prospective transferee, if convicted, would be prohibited under state or federal law from purchasing, receiving, or possessing a firearm and either there has been no final disposition of the case or the final disposition is not noted in the other databases; or
  • Is the subject of an indictment, information, or a felony complaint alleging that the prospective transferee has committed a crime punishable by imprisonment for a term exceeding one year as defined in 18 U.S.C. sec. 921(a)(20), as amended, and either there has been no final disposition of the case or the final disposition is not noted in the other databases.

Registering a Firearm

Firearm registration is strictly prohibited in Colorado.[3]

Concealed Carry

A Concealed Handgun Permit is required to carry a concealed weapon in the state of Colorado.[4]

How to Apply
