Colorado firearms laws govern how residents and visitors may purchase, possess, carry, and use firearms within the state. This guide covers the most important aspects of Colorado gun laws as of 2026, including purchase requirements, carry permits, waiting periods, and self-defense statutes. Always consult official state statutes and legal counsel for binding legal guidance.
Permit to purchase: No permit required to purchase. Colorado does not require a separate state-level permit to purchase firearms beyond the standard federal requirements. Buyers must be at least 21 years old for handguns and 18 years old for long guns (rifles and shotguns). All purchases through licensed FFL dealers require a federal NICS background check.
Background checks: CBI background check (state-run, not just NICS). When you purchase a firearm on WeaponDepot, it ships to your chosen FFL dealer in Colorado who handles all required paperwork and background check processing.
Waiting period: No waiting period (3-day delivery delay for some).
Open carry: Legal in most areas (Denver prohibits).
Concealed carry: CHP required from county sheriff. Colorado operates under a permit-based carry system. Residents must apply for and obtain a concealed carry permit before legally carrying a concealed firearm in Colorado. Check local requirements for application procedures, fees, and training requirements.
15-round magazine limit, universal background checks. Federal restrictions on NFA items (short-barreled rifles, suppressors, machine guns) still apply and require ATF approval through the appropriate tax stamp process.
Colorado follows the duty-to-retreat doctrine, which generally requires individuals to retreat if safely possible before using deadly force in public. The state also provides Castle Doctrine protections, protecting individuals who use force against intruders in their home, vehicle, or place of business.
Colorado has enacted a red flag law (Extreme Risk Protection Order). This law allows law enforcement or family members to petition a court to temporarily remove firearms from individuals deemed a danger to themselves or others. Additionally, Colorado allows local municipalities to enact their own firearms regulations.
When you purchase a firearm on WeaponDepot, it ships directly to a licensed FFL dealer in Colorado. At the dealer, you complete ATF Form 4473 and undergo the required background check. FFL transfer fees in Colorado typically range from $15 to $75 per firearm. Use our FFL dealer directory for Colorado to compare fees and find the best dealer near you.
