   Gun Show Vendor

   Certification of Compliance

   As a vendor of firearms or firearm components at the gun show operated by [promoter's name] to be held [date or dates of gun show] in [city or town, if applicable], _______ county, Colorado, I certify to the promoter of the gun show that:

   I am a federal firearms licensee and I am permitted by the state of Colorado to sell firearms at retail.

   I will display a copy of the federal license and state permit at my booth at the gun show.

   I have never been convicted of illegal activity involving firearms.

   I will ensure that all firearms and frames or receivers of firearms sold by me at the gun show will be preceded by a background check of the purchaser and comply with the three-day waiting period required in state law.

   I will display and offer for sale or transfer ammunition in compliance with any applicable state or federal law.

   I will not sell or transfer any weapons or ammunition that I am prohibited from selling pursuant to federal or state law, including, but not limited to:

   Ammunition magazines that allow for more than 15 rounds of ammunition;

   Firearms that have fixed magazines that allow for more than 15 rounds of ammunition;

   Firearms or frames or receivers of a firearm, including unfinished frames or receivers, that are unserialized; and

   Dangerous weapons, as defined in section 18-12-102, C.R.S., and illegal weapons, as defined in section 18-12-102, C.R.S., unless the transferee presents a valid permit for possession of the weapon.

   Furthermore, I am aware of additional prohibited items in the city or town and county in which the gun show will be held, and I will not engage in the sale of those items.

   I understand that if I sell prohibited items or conduct sales in dangerous or illegal weapons without the transferee presenting a valid permit, I may be subject to criminal penalties under federal, state, or local laws and may be prohibited from participating in future gun shows in the state of Colorado.
