! For each customer who leaves with a purchased firearm,
verify that each firearm sold at a gun show is delivered in
compliance with the required the 3-day waiting period; and
! Post certain notices at the gun show.
Violating any of these provisions is unlawful gun show management,
which is a class 2 misdemeanor; except that a second or subsequent
offense is a class 1 misdemeanor and, in addition to a criminal penalty,
the promoter is prohibited from acting as a gun show promoter for 5
years.
The bill prohibits a person from participating in a gun show as a
gun show vendor if the person is not a federal firearms licencee, does not
hold a valid state firearms dealer permit, has been convicted of a second
offense of unlawful gun show vendor activity as described in the bill, or
has not completed a gun show certification for the gun show promoter as
required in the bill. Unlawful participation in a gun show as a gun show
vendor is a class 2 misdemeanor; except that a second or subsequent
offense is a class 1 misdemeanor.
Before participating in a gun show, a gun show vendor is required
to certify to the gun show promoter that the vendor satisfies the
requirements to be a gun show vendor and will comply with federal, state,
and local laws while participating in the gun show.
While participating in a gun show, a gun show vendor shall display
copies of the vendor's federal firearms license and state firearms dealer
permit, keep firearms unloaded and securely affixed to the vendor's
countertop or wall, secure ammunition in an enclosed display case or
behind the vendor's counter or other customer access prevention device,
and include with each sold firearm written information describing secure
storage and lost or stolen firearm reporting requirements in state law.
Unlawful gun show vendor activity is a class 2 misdemeanor; except that
a second or subsequent offense is a class 1 misdemeanor and the person
is prohibited from participating as a vendor at a gun show.
The bill maintains the requirement in existing law that a gun show
vendor conduct a background check for each firearm transfer at a gun
show.
Be it enacted by the General Assembly of the State of Colorado:1
SECTION 1. Legislative declaration. (1) The general assembly2
finds and declares that:3
(a) Gun violence remains a significant threat to public safety in4
Colorado, causing harm to individuals, families, and communities across5
1238-2- the state. Effectively addressing gun violence requires a comprehensive1
strategy that includes both preventing illegal firearm transfers and2
ensuring responsible ownership practices.3
(b) Gun shows serve as important venues for the lawful sale and4
transfer of firearms. However, these events present unique challenges for5
regulating the movement of firearms and preventing illegal trafficking.6
While gun shows are lawful and cater primarily to responsible gun7
owners, they can also provide opportunities for firearms to be transferred8
without proper oversight, potentially leading to unlawful possession and9
misuse.10
(c) It is essential for Colorado to implement strong regulatory11
measures at gun shows to mitigate the risks associated with unregulated12
or improper firearm transfers and the unlawful sale of large-capacity13
magazines, including magazines that are designed to be readily converted14
to accept more than 15 rounds of ammunition, and unserialized firearms15
or frames or receivers of a firearm. The regulatory measures include the16
requirement for gun show promoters and vendors to follow security17
protocols, conduct background checks, and ensure firearms are stored and18
handled safely.19
(d) This legislation requires gun show promoters to develop and20
implement security plans, secure liability coverage, and verify that21
firearms are sold or transferred in compliance with state and federal laws.22
In addition, vendors are required to comply with mandatory background23
checks and adhere to federal, state, and local firearm laws and proper24
firearm storage practices.25
(e) By fostering responsible practices at gun shows, Colorado can26
reduce the potential for illegal firearm trafficking and decrease the27
1238
-3- likelihood that firearms will be misused in criminal acts or violence; and1
(f) Reducing gun violence and ensuring the safe and lawful2
transfer of firearms is a shared responsibility between the state, local3
governments, and communities. This act represents a step toward4
ensuring the safety of all Coloradans, while balancing the rights of5
responsible gun owners.6
(2) Therefore, the general assembly declares that regulating gun7
shows to ensure the safety, security, and lawful transfer of firearms is of8
both local and statewide concern, aimed at reducing gun violence and9
promoting responsible firearm ownership practices throughout Colorado.10
SECTION 2. In Colorado Revised Statutes, repeal and reenact,11
