Colorado Gun Control Laws

By FindLaw Staff | Legally reviewed by Maddy Teka, Esq. | Last reviewed May 25, 2021

Getting a handle on Colorado gun laws can be tricky, especially when states and the federal government have separate and sometimes overlapping statutes. Where they intersect, federal law always trumps, so Colorado gun owners are also subject to the Brady Handgun Violence Prevention Act and the National Firearms Act, and should be familiar with both statutes.

Even under the Second Amendment, states can regulate the purchase and use of certain weapons and accessories. Sawed-off shotguns and silencers, for example, are illegal under Colorado's gun control laws. However, Colorado also has no waiting period for prospective gun buyers, so long as they meet certain eligibility requirements for gun ownership.
