Beginning in August 2023, it will be a misdemeanor for a person under the age of 21 to purchase firearms.1 It will also be a misdemeanor to sell a firearm to a person under the age of 21.2

In Colorado, any person under age 18 may not knowingly possess a handgun, except:

  • When in attendance at a hunter’s or firearms safety course;
  • During lawful firearm or target shooting;
  • During certain organized competitions or performances;
  • When hunting or trapping with a valid state license;
  • When traveling to or from such activities as previously noted;
  • When on property under the control of the person’s parent, legal guardian or grandparent with the permission of such person’s parent, legal guardian or grandparent; or
  • When at the person’s residence, with the permission of the person’s parent or legal guardian, for the purpose of lawful self-defense.3

Colorado does not provide a minimum age to possess rifles or shotguns. Colorado also provides no minimum age for the purchase of a handgun or a long gun, although federal age restrictions  still apply.

For additional age-related restrictions, see the Colorado Child Access Prevention section.
