Colorado Gun Laws 2026

Purchasing a Firearm in Colorado

Colorado does not require a special permit or license to purchase a firearm. Buyers must be at least 18 years old for long guns (rifles and shotguns) and 21 for handguns when purchasing from a licensed dealer, in accordance with federal law. All buyers must be able to pass a background check and must not be a prohibited person under federal or state law.

Colorado requires background checks for all firearm sales, including private transactions between individuals. This universal background check requirement means that even sales at gun shows between private parties must go through a licensed dealer or state-run system. This is one of the more comprehensive background check requirements in the country.

Colorado imposes a 3-day waiting period on firearm purchases. After completing the background check, the buyer must wait 3 days before taking possession of the firearm. Some exemptions may apply, such as for current concealed carry permit holders, law enforcement, or in cases of documented threats.

Concealed Carry in Colorado

Colorado has a permit-based concealed carry system. Colorado requires a concealed carry permit or license to carry a concealed handgun in public. The state operates a shall-issue system, meaning the issuing authority must grant the permit if the applicant meets all legal requirements. There is no discretionary denial. Requirements typically include minimum age, background check, and in some cases a firearms safety training course.

Concealed carry permit holders (where applicable) should be aware of restricted locations where carry is prohibited regardless of permit status. These typically include federal buildings, courthouses, schools and school zones, polling places on election day, and any private property where firearms are prohibited by the owner. Posted signage requirements vary by state — in Colorado, always look for posted signs at building entrances.

Open Carry Laws

Open carry of firearms is legal in Colorado. A permit may be required in certain areas. Open carry refers to carrying a firearm in a manner that is visible to others, such as in a belt holster. While legal at the state level, some municipalities or specific locations (government buildings, schools, courthouses) may restrict open carry. It is important to be aware of local ordinances and posted signage.

Assault Weapons and Magazine Restrictions

Colorado does not have an assault weapons ban. Semi-automatic firearms of all types may be legally purchased, possessed, and carried (subject to general firearms laws). There are no state-level restrictions on specific firearm features such as pistol grips, adjustable stocks, or flash suppressors.

Colorado limits magazine capacity to 15 rounds. Magazines that can hold more than 15 rounds of ammunition are prohibited from sale and, in some cases, possession. Magazines lawfully owned before the restriction took effect may be grandfathered. This applies to both handgun and rifle magazines.

Red Flag Law

Colorado has enacted a red flag law, also known as an Extreme Risk Protection Order (ERPO) law. This allows family members, law enforcement, or in some states other designated individuals to petition a court to temporarily remove firearms from a person who is deemed to be a danger to themselves or others. The process involves a hearing, and the subject has the right to contest the order. If granted, firearms are temporarily confiscated and the individual is prohibited from purchasing new firearms for the duration of the order, typically 6-12 months.

Gun Show Regulations in Colorado

Gun shows in Colorado follow the same laws that apply to all firearm sales. Licensed dealers (FFLs) at gun shows must conduct background checks on all purchases, just as they would at their retail location. All sales at gun shows, including private sales between individuals, require a background check under state law. Gun shows typically require all firearms brought in for sale to be unloaded and secured with cable ties or similar safety devices. Individual show promoters may set additional rules.

FFL Transfer Rules

When purchasing a firearm online, the firearm must be shipped to a Federal Firearms Licensee (FFL) in Colorado for the transfer. The buyer then completes the standard Form 4473 and background check at the FFL's location. FFL transfer fees in Colorado typically range from $20 to $75 per firearm.
