In this article, our Denver Colorado criminal defense lawyers will address the following key issues regarding open carry laws:1. Eligibility
In Colorado, you may openly carry a firearm unless:- You are under 18 years of age,1
- You are legally prohibited from owning a firearm (for example, you are a convicted felon),2 or
- You are subject to a Colorado protective order that prohibits firearm possession,
- You are on federal property (such as a National Park, courthouse, airport, post office or federally subsidized housing),
- You are in your car with a loaded firearm that is not a pistol or revolver,3
- The firearm is loaded and you are in a public transportation facility,4
- You on are on the grounds of a school or university (whether public or private), or
- You are on government property (such as police stations or city parks) within the limits of Denver or another jurisdiction that prohibits open carry under the “home rule” powers of cities and counties (see below).

2. CCWs
Your Colorado concealed handgun permit (CCW permit) has nothing to do with Colorado open carry. However, if you possess a concealed carry permit, you may carry weapons both openly and concealed wherever not prohibited by law. Colorado is a “must-issue” concealed carry permit state. The local sheriff’s office will issue a state permit to carry a concealed firearm to anyone who is- at least 21 years of age and
- not prohibited by law from possessing a firearm.
3. Penalties
Since open carry is legal in Colorado (other than in Denver), there are no penalties unless you openly carry a prohibited weapon or are legally prohibited from possessing a handgun. A first-time violation of carrying a prohibited weapon under 8-12-106 C.R.S is usually a class 1 misdemeanor in Colorado. The punishment is:- Up to 364 days in jail, and/or
- Up to $1,000 in fines.
- 1 to 3 years in Colorado State Prison (with 2 years mandatory parole), and/or
- $1,000 to $100,000 in fines.
- 1 to 3 years in prison, and/or
- $1,000 to $100,000 in fines.
4. “Home Rule”
Under Article 20, Section 6 of the Colorado Constitution, local cities and counties have the right to pass laws affecting their own jurisdictions as long as they do not directly contradict state or federal law. Denver tested this clause when it passed Section 38-117(b) of the Denver Revised Municipal Code, which makes it unlawful for any person “to carry, use or wear any dangerous or deadly weapon, including, but not by way of limitation, any pistol, revolver, rifle, shotgun . . . or any other dangerous or deadly weapon” unless specifically permitted under state law. Denver’s law was challenged in the landmark case Denver v. State of Colorado. The judge sided with Denver, noting that “the State’s interest in allowing the general open carry of firearms is insubstantial and is far outweighed by Denver’s local interest in regulating firearms more strictly in an urbanized area.”
