No guns signs (private property)
'No guns' signs do not have the force of law. If you carry past a 'no guns' sign on private property, you may be asked to leave or disarm. Failure to comply would be trespassing. Signs on private property may cite 18-4-504 (trespassing). Local governments must post 'no guns' signs to ban open carry in public buildings. 29-11.7-104

Federally Prohibited Places
Firearms, loaded or unloaded, concealed or openly carried, are prohibited in the following places
Interstate Transportation Protection 18 USC § 926A
This section was intended to protect innocent passage of travelers who might have a firearm prohibited by local jurisdiction. For instance, a resident of a frontier state driving through California with an 'assault weapon' to another free state. The trip must be from one free state to another, the firearm unloaded, and neither the firearm nor any ammunition is readily accessible from the passenger compartment. In the case of a vehicle without a compartment separate from the driver’s compartment the firearm or ammunition shall be contained in a locked container other than the glove compartment or console.
Airports/Aircraft 49 CFR 1540.111 and 49 USC § 46505
Under federal law (local laws may differ), firearms are prohibited beyond the TSA checkpoints. You also cannot attempt to enter a TSA checkpoint while armed, even by mistake. Check your bags! Even loose ammunition, empty magazines, spent cases, and miscellaneous gun parts have caused problems and prosecutions for travelers. Learn more about the TSA regulations.
Military Bases
Self-defense firearms are generally prohibited on base. Almost uniformly, civilians may not possess firearms on base. Service-members may be required to store their weapons as their commanding officer directs. Check individual base and service branch regulations. Additionally, army regulations are here and the oft-mentioned Bush-era directive is here (reaffirmed in 2011).
National Park
Section 512, Credit CARD Act of 2009 (and 54 USC § 104906) changed federal law to make park firearm regulations reflect state law. Typically, the only restrictions on firearm carry are state and local laws. If it is legal elsewhere in the state, it is legal in the park and sections that conflict with state law regarding carrying and possessing firearms (but not shooting bans) do not apply. So though on National Park Service lands (National Parks, Monuments, etc.) carrying a firearm or possessing loaded firearms are prohibited in vehicles (unless one has a special park permit, usually for hunting), this does not apply if the state allows open and/or concealed carry, or loaded/unloaded firearms in vehicles.
The park buildings (visitor centers, offices, etc.) are still federal facilities and off-limits to firearms. Discharge of firearms, except when lawfully hunting, is generally prohibited. Discharge of firearms, except when lawfully hunting, is generally prohibited. NPS pamphlet here. The same applies for National Wildlife Refuges, 16 USC § 1a–7b.
National Forest or Bureau of Land Management (BLM) lands in Colorado have no ban on the carry of firearms.
Indian Reservations
Firearm carry on Indian reservations is a gray area. Some reservations do permit concealed carry with a valid concealed firearm permit, however, it may vary. Tribes cannot enforce tribal law on non-tribal members, though they can enforce state and federal law. You may be trespassed from the reservation and have your firearm confiscated. One should contact individual reservation authorities for clarification of their regulations.
- Inside federal facilities (including courthouses and offices like a Social Security office);
- On military bases (military personnel should refer to DoD policy and post orders regarding storing personal weapons on base);
- The Post Office property (includes the parking lot), but not post-office windows in stores (contract stations);
- VA hospitals/facilities including federal veterans' cemeteries (carrying).

Denver
Denver is a special case. The following special exemptions apply and locals laws may be more restrictive than above.
'Assault weapons' (including the modern sporting rifle and shotguns with more than six shells capacity) and magazines exceeding 21 rounds in capacity are banned (state law is 15). This does not apply to grandfathered guns with a permit or to non-residents traveling through Denver. Open carry within Denver limits is illegal.
The City and County of Denver is a home rule city created and organized under Article XX, Section 6 of the Colorado Constitution (the “home rule amendment”). Under the home rule amendment, a home rule municipality has the supreme power to legislate in matters of local concern. Historically, Denver has had a range of ordinances controlling various aspects of the possession, use and sale of firearms in the city. (CO Denver Ruling)
The Supreme Court's opinion allowing Denver's strict gun control regime is based on the fact it is organized differently than most cities. Under home rule, it is not subject to certain limitations that other cities are subject to. While that issue is one unique to Colorado, the arguments to support the validity of the anti-gun ordinances are specious and are a stunning abuse of logic.
Denver has banned open carry since 1973, under the premise that Denver is 'special' and somehow different than the rest of the state. Arguments seemed to be based on the fallacy that an openly carried handgun equates target shooting and that allowing open carry in the city would lead to people getting shot. The Supreme Court found that Denver has the right to regulate open carry because it is urbanized.
When it comes to assault weapons the judge literally found that 'Denver is special' and upheld the laws. " Like open carry, there is little need for statewide uniformity given the unique characteristics of Denver, and the impact of the ordinances on people living outside of Denver is minimal." In other words, Denver residents are less entitled to full Second Amendment rights than other Colorado residents.

State Preemption
Colorado's state preemption of local firearm laws is rather weak. As you have read above, Denver's exemptions border on ludicrous. Additionally, unlike other states, which usually reserves firearm regulation power to the legislature and grants limited authority to local governments, Colorado only prohibits local governments from making certain laws in a very narrow field. Local governments are prohibited from regulating concealed carry only.
There exists a widespread inconsistency among jurisdictions within the state with regard to firearms regulations. This inconsistency among local government laws regulating lawful firearm possession and ownership has extraterritorial impact on state citizens and the general public by subjecting them to criminal and civil penalties in some jurisdictions for conduct wholly lawful in other jurisdictions. Inconsistency among local governments of laws regulating the possession and ownership of firearms results in persons being treated differently under the law solely on the basis of where they reside, and a person's residence in a particular county or city or city and county is not a rational classification when it is the basis for denial of equal treatment under the law. This inconsistency places citizens in the position of not knowing when they may be violating the local laws and therefore being unable to avoid violating the law and becoming subject to criminal and other penalties. 29-11.7-101(d)-(g)
29-11.7-102 Firearms database-prohibited
(1) A local government, including a law enforcement agency, shall not maintain a list or other form of record or database of:
(a) Persons who purchase or exchange firearms or who leave firearms for repair or sale on consignment;
(b) Persons who transfer firearms, unless the persons are federally licensed firearms dealers;
(c) The descriptions, including serial numbers, of firearms purchased, transferred, exchanged, or left for repair or sale on consignment.
29-11.7-103 Regulation-type of firearm-prohibited
A local government may not enact an ordinance, regulation, or other law that prohibits the sale, purchase, or possession of a firearm that a person may lawfully sell, purchase, or possess under state or federal law. Any such ordinance, regulation, or other law enacted by a local government prior to March 18, 2003, is void and unenforceable.
29-11.7-104 Regulation-[open] carrying-posting
A local government may enact an ordinance, regulation, or other law that prohibits the open carrying of a firearm in a building or specific area within the local government's jurisdiction. If a local government enacts an ordinance, regulation, or other law that prohibits the open carrying of a firearm in a building or specific area, the local government shall post signs at the public entrances to the building or specific area informing persons that the open carrying of firearms is prohibited in the building or specific area.
18-12-105.6 Limitation on local ordinances regarding firearms in private vehicles
Notwithstanding any other provision of law, no municipality, county, or city and county shall have the authority to enact or enforce any ordinance or resolution that would restrict a person's ability to travel with a weapon in a private automobile or other private means of conveyance for hunting or for lawful protection of a person's or another's person or property while traveling into, through, or within, a municipal, county, or city and county jurisdiction, regardless of the number of times the person stops in a jurisdiction.
