How to Sell a Gun in Colorado?

Selling a gun in Colorado requires knowledge of the state’s laws to ensure gun owners are in compliance and don’t make any mistakes. The state of Colorado has various laws concerning the ownership, transfer, and the carrying of firearms. If you’re considering selling a gun to another individual, make sure you’re up to speed with the laws that regulate transfers to ensure you’re in compliance and not breaking any laws.

The following information is from the Colorado Bureau of Investigation.

Buying and Selling a Firearm in Colorado

Anyone purchasing a firearm from a licensed firearms dealer must complete a Bureau of Alcohol, Tobacco & Firearms form 4473. A firearms purchaser must, under the permanent provisions of the Federal Brady Law, also undergo a National Instant Criminal Background Check System check, which will be performed by the licensed firearms dealer.

The check will indicate to the dealer whether the purchaser’s background allows for the person to complete the purchase of the firearm. If the check disallows the sale for no warranted reason, there is an appeal process the purchaser can pursue to receive the necessary clearance to complete the purchase.

Selling a Gun to a Private Party in Colorado

Selling to a Federal Firearms License (FFL) is much easier but if you want to sell to a private party you’ll want to be informed.

Colorado gun owners who are selling to a non-immediate family member must conduct a background check through a Federal Firearm Licensee.  However, immediate family members do not need background checks done to transfer firearms between one another.  Immediate family is defined as spouses, parents, children, siblings, grandparents, grandchildren, nieces, nephews, first cousins, aunts, and uncles (in-laws do not apply). The firearm sold should not be transferred to any family member who is prohibited from purchasing and/or possessing firearm (CRS 18-12-112)

A person who violates a provision of this section commits a class 1 misdemeanor and shall also be prohibited from possessing a firearm for two years per state law. C.R.S. 18-12-112 (9)(a)
