Q. Can I legally possess a semi-automatic, so-called "Assault Weapon" in Colorado?
A. Yes. Colorado has no state laws which regulate semi-automatic firearms any differently from other firearms. Colorado does have a state law regulating certain ammunition magazines, as noted above. Denver purports to regulate assault weapons. As noted above the state law pre-emption of this ordinance was rejected in the City & County of Denver v. State trial court decision. The Denver ordinance reads:
Sec. 38-130. Assault weapons.
(a) Legislative intent. The city council hereby finds and declares that the use of assault weapons poses a threat to the health, safety and security of all citizens of the City and County of Denver. Further, the council finds that assault weapons are capable both of a rapid rate of fire as well as of a capacity to fire an inordinately large number of rounds without reloading and are designed primarily for military or antipersonnel use. The city council finds that law enforcement agencies report increased use of assault weapons for criminal activities. This has resulted in a record number of related homicides and injuries to citizens and law enforcement officers. It is, therefore, the intent of the city council to place reasonable and necessary restrictions on the sale and possession of assault weapons while placing no restrictions on the right of citizens to use weapons which are primarily designed and intended for hunting, target practice and other legitimate sports or recreational activities and the protection of home, person and property.
(b) Definitions. The following words and phrases, when used in this section, shall have these meanings respectively ascribed to them:

(2) Any assault weapon which is being used as a movie prop for any motion picture or television program which is being filmed in whole or in part within the City and County of Denver if, prior to such use, the police department is notified in advance in writing of the date, time, location, production schedule and days upon which such use shall take place and the type and serial numbers of the firearms.
(3) It shall be an affirmative defense to charges brought under this section that the transportation of an assault weapon:

(1) Said weapon is properly identifiable and contains its original serial number.
(2) An application for a permit for each assault weapon is filed with the police department within sixty (60) days of the effective date of this section pursuant to such procedures as the department may establish. The application shall contain a description of the firearm that identifies it uniquely, including all identification marks and numbers, the full name, address, date of birth and fingerprints of the owner and the address where such assault weapon will be stored and such other information as the department may deem appropriate. The place of storage and possession shall not be changed without notification to the department of the proposed change in location and when said weapon will be transported.
