Judge Upholds Colorado Firearm Age Restriction Law

Chief U.S. District Judge Philip A. Brimmer upheld Colorado's 2023 law requiring individuals to be at least 21 years old to purchase any firearm, dismissing a challenge from Rocky Mountain Gun Owners and two plaintiffs under 21. The law, signed by Governor Jared Polis, expands existing federal handgun restrictions to rifles and shotguns, with exceptions for active-duty military and peace officers on duty. Judge Brimmer cited prior 10th Circuit decisions, finding age-based purchase limits outside Second Amendment protections due to a legal 'safe harbor.' Colorado officials argue the measure is intended to reduce gun violence and youth suicides as part of broader public safety goals. The ruling prompted declines in gun manufacturer stocks and heightened attention among crypto traders to regulatory impacts on risk assets. Gun rights advocates, who challenged the law immediately after its enactment, may pursue further appeals as national debates over firearm age limits continue.
