Colorado State Laws for Private Sales

In Colorado, private gun sales between two non-licensed individuals are generally legal, but there are regulations in place to ensure compliance with state laws and federal background check requirements. Specifically, the majority of private gun transfers must be facilitated through a Federal Firearms Licensee (FFL), who conducts a background check on the buyer to verify that they are eligible to possess firearms. This requirement was implemented in 2013 to help prevent firearms from falling into the wrong hands and protect both the buyer and seller. However, there are some exceptions to the requirement, such as transfers between immediate family members or temporary transfers for hunting or sporting events. Overall, private gun sales in Colorado are legal, but subject to certain regulations to help ensure public safety.

Background Check and Approval Process

To sell a gun to a private party in Colorado, you must follow these steps:

  • Arrange for a background check and Colorado Bureau of Investigation (CBI) approval for the private gun transfer through an FFL.
  • The FFL is required to record and retain transfer records. Both the transferor and transferee should receive a copy of the background check results.
  • The transferee is prohibited from accepting possession of the firearm until the background check is completed and approved.

Failure to comply with the background check requirement can result in severe consequences, including:

  • A class 1 criminal misdemeanor
  • Civil liability
  • Prohibition of future firearm possession

However, there are exceptions to the background check requirement. These include:

  • Transfers between immediate family members
  • Temporary transfers (e.g., for hunting or self-defense purposes)
  • Transfer of antique firearms, curios, or relics

  • Individuals subject to certain restraining orders
  • Individuals with a mental health adjudication or commitment

In addition, the state bans specific types of firearms, such as:

  • Assault weapons
  • Large-capacity magazines
  • Bump stocks

Failure to comply with firearm ownership and transfer laws can result in criminal charges, fines, and forfeiture of firearms.

Federal Laws for Gun Sales

In Colorado, federal laws govern the sale and possession of firearms, but state laws also play a role in shaping the state's approach to gun regulation. Understanding the laws that govern firearms sales in Colorado is important for both gun owners and those who wish to purchase a firearm. In this context, this article will explore the federal laws that regulate gun sales in Colorado, and how these laws interact with state regulations.

A. Purchasing from a Licensed Dealer

When buying a gun from a licensed firearms dealer, you must complete an ATF form 4473 and undergo a National Instant Criminal Background Check System (NICS) check. The Federal Brady Law mandates this background check. If the check disallows the sale without a warranted reason, an appeal process is available. Licensed firearms dealers are prohibited from selling firearms to anyone prohibited from possessing them.

B. Federal Legislation Updates

Colorado's universal background check law is more restrictive than current federal law relating to private firearm transfers. H.R. 8, the Bipartisan Background Checks Act of 2021, passed the U.S. House of Representatives and is now before the U.S. Senate for debate. The final version of the bill remains uncertain.
