On 06/19/2021, Colorado House Bill 21-1298 went into effect. This means that “It is unlawful for a licensed gun dealer to transfer a firearm to a transferee until the dealer has obtained approval for the firearms transfer from the Bureau, after the Bureau has completed any background check required by State or Federal law.” This applies to background checks that take longer than 3 business days to complete.

You can review the details of the bill at https://leg.colorado.gov/bills/hb21-1298

Thank you.
