Concealed and open carry 
Colorado is a "shall-issue" state for concealed carry. Permits are issued by the county sheriff, and are valid for five years. Applicants must demonstrate competence with a handgun, either by passing a training class or by other means.
Open carry, as well as possession of a handgun in an automobile, is generally permitted without a license. However, local governments may prohibit open carry, and the city of Denver has done so. When a rifle or shotgun is transported in a vehicle, there may not be a round in the chamber.
Other laws 
Colorado has state preemption for firearm laws. However, due to a court ruling, Denver can regulate open carry in the city limits. The ruling only applies to Denver as the court decision did not rule on any other areas outside of what ordinances were covered by Denver.
Effective July 1, 2013, Colorado will require background checks for all firearm sales. Magazines that can hold more than 15 rounds, cannot be sold or transferred.
Gun control lawsuit 
A lawsuit over the legality of the magazine ban and background check laws has been filed by 54 of the 62 elected county Sheriffs and 21 sporting and outdoor groups and Colorado companies. The suit alleges that the laws violate the Second and Fourteenth amendments, and state that the laws would be impossible to enforce.
