Understanding Gun Laws in Colorado: Lawyer Insight
Colorado’s firearm regulations represent a complex intersection of state constitutional protections, federal law requirements, and local ordinances that gun owners must navigate carefully. Whether you’re a long-time Colorado resident, a new transplant, or someone considering firearm ownership in the state, understanding these laws is essential to ensure legal compliance and responsible gun ownership. The landscape of Colorado gun laws has evolved significantly over the past decade, with several landmark legislative changes affecting how residents can purchase, carry, and store firearms.
Colorado maintains a unique position among states, balancing Second Amendment protections with public safety regulations. The state has implemented universal background checks, red flag laws, and magazine capacity restrictions while still preserving relatively accessible pathways to firearm ownership for qualified individuals. This comprehensive guide provides insights into the current legal framework governing firearms in Colorado, helping you understand your rights and responsibilities as a gun owner or prospective purchaser.

Colorado’s Constitutional Framework for Gun Ownership
Colorado’s approach to gun rights is grounded in both the Second Amendment to the U.S. Constitution and Article II, Section 13 of the Colorado Constitution, which explicitly protects the right to bear arms. The Colorado Constitution states that the people have the right to bear arms in defense of themselves and the state, providing a strong textual foundation for firearm ownership rights within the state.
The Colorado Supreme Court and federal courts have interpreted these constitutional provisions to protect an individual’s right to possess firearms for lawful purposes, including self-defense. However, this right is not absolute and can be subject to reasonable regulations designed to promote public safety. Colorado has exercised its regulatory authority by implementing several firearms restrictions that courts have generally upheld as constitutional. Understanding this balance between rights and regulations is fundamental to comprehending Colorado’s gun law landscape.
When examining Colorado gun laws, it’s important to recognize that the state has consistently held that certain regulations do not violate constitutional protections. The Colorado legislature has demonstrated its commitment to both protecting gun ownership rights and implementing safety measures, creating a regulatory environment that attempts to serve both interests. This balanced approach distinguishes Colorado from more restrictive states while maintaining stricter regulations than some neighboring jurisdictions.

Background Checks and Permit Requirements
One of the most significant aspects of Colorado gun laws is the universal background check requirement implemented through Senate Bill 13-197 in 2013. This law mandates that all firearm transfers, with limited exceptions, must be processed through a licensed firearms dealer who conducts a background check. Unlike many states that only require background checks for gun shop purchases, Colorado’s universal background check law extends to private sales, gifts between family members (with some exceptions), and transfers between friends.
The background check process in Colorado involves the Colorado Bureau of Investigation (CBI) conducting a comprehensive review of the purchaser’s criminal history, mental health records, and other disqualifying factors. The CBI has up to ten business days to complete the background check, though many checks are processed much more quickly. If the CBI cannot determine whether a person is qualified to possess a firearm within the ten-day period, the dealer may release the firearm to the purchaser, a provision known as the “default proceed” rule.
Colorado does not require a permit to purchase firearms, distinguishing it from states with more restrictive purchasing regulations. However, individuals who wish to carry a concealed handgun must obtain a concealed carry permit, which involves a separate application process. The permit application requires submitting fingerprints, completing a background check, and paying the associated fees. Understanding the distinction between purchase background checks and carry permits is essential for Colorado gun owners.
Certain individuals are prohibited from purchasing or possessing firearms in Colorado, including convicted felons, individuals with domestic violence convictions, those adjudicated mentally ill, and individuals subject to protective orders. These prohibitions align with federal law requirements and are enforced through the background check system.
Concealed Carry Permits and Open Carry Laws
Colorado permits both open carry and concealed carry of firearms, though with specific regulations governing each method. Open carry—carrying a firearm visibly on your person without a permit—is legal throughout most of Colorado for individuals legally allowed to possess firearms. However, local jurisdictions have the authority to restrict or prohibit open carry within their boundaries, which has led to a patchwork of regulations across different municipalities.
The concealed carry permit system in Colorado is administered at the county level, with each county sheriff’s office processing applications. To obtain a concealed carry permit, applicants must be at least eighteen years old (or twenty-one for handguns if not a military member), pass a background check, be a Colorado resident or have a residence in the state, and pay the applicable fees. The permit is valid for five years and must be renewed before expiration.
Colorado law does not require a permit to carry a firearm openly, but it does require a permit to carry concealed. This distinction is important because many individuals prefer concealed carry for safety and discretion reasons. The concealed carry permit process is relatively straightforward compared to some states, though applicants should be prepared to provide documentation of residency and submit to the background check process.
Out-of-state concealed carry permits are not automatically recognized in Colorado, though the state has reciprocity agreements with numerous other states. Visitors to Colorado who hold valid concealed carry permits from their home states should verify whether Colorado recognizes their permits before carrying firearms in the state. The Colorado Sheriff’s Association maintains current information about reciprocity agreements.
Magazine Capacity Restrictions and Ammunition Regulations
Colorado implemented magazine capacity restrictions through Senate Bill 13-197, limiting the sale and transfer of large-capacity magazines to those holding no more than fifteen rounds. This restriction applies to the sale, transfer, and possession of magazines manufactured or sold after July 1, 2013. Magazines manufactured before this date and lawfully possessed are generally not subject to the restriction, though selling or transferring them to others may violate the law.
The magazine capacity restriction has been subject to legal challenges, with courts examining whether the limitation constitutes a constitutional infringement on Second Amendment rights. Colorado courts have upheld the restriction as a reasonable regulation, balancing public safety interests with gun ownership rights. However, gun rights advocates continue to challenge the restriction in various forums.
Colorado does not currently impose specific restrictions on ammunition purchases or possession, unlike some states that have implemented ammunition taxes or registration requirements. However, federal law prohibits the sale of certain types of ammunition, and Colorado enforces these federal restrictions. Additionally, local jurisdictions may implement ammunition regulations within their boundaries, so checking local ordinances is advisable.
Ammunition sales through federally licensed firearms dealers require background checks in Colorado, a requirement implemented through the same universal background check law that governs firearm purchases. This means that purchasing ammunition involves the same ten-day waiting period and background check process as purchasing a firearm.
Red Flag Laws and Firearm Removal Orders
Colorado’s “red flag” law, formally known as the Extreme Risk Protection Order (ERPO) law, allows law enforcement and family members to seek court orders requiring the temporary removal of firearms from individuals deemed to pose a significant risk of harm to themselves or others. This law, implemented through Senate Bill 19-038, represents one of Colorado’s most controversial firearms regulations.
Under the ERPO law, police officers, family members, healthcare providers, and school officials can petition a court for an order requiring someone to surrender their firearms temporarily. The law provides for both emergency protection orders, which can be granted ex parte (without the respondent present) for up to fourteen days, and longer-term extreme risk protection orders lasting up to one year. The law includes provisions for the respondent to request a hearing and present evidence challenging the order.
The ERPO law has generated significant legal debate regarding due process protections and Second Amendment implications. Supporters argue the law provides an important tool for preventing suicide and mass violence, while critics contend it may violate due process rights by removing firearms without adequate procedural safeguards. Colorado courts have addressed some of these concerns by requiring clear and convincing evidence before issuing extended orders.
Understanding the ERPO law is important for gun owners because behavior suggesting suicidal ideation or serious threats toward others could trigger an order. Additionally, individuals subject to ERPO orders have the right to petition for their termination and retrieve their firearms once the court determines the risk has been adequately mitigated.
Local Ordinances and Municipal Restrictions
While Colorado state law permits relatively broad firearm ownership and carry rights, local jurisdictions have significant authority to implement additional restrictions. Cities and counties can prohibit open carry, restrict firearm possession in certain locations, and implement additional licensing requirements. This creates a complex patchwork of regulations that vary significantly depending on where in Colorado you reside or travel.
Denver, Colorado’s largest city, has implemented some of the state’s most restrictive firearms ordinances. Denver prohibits the sale of semi-automatic weapons and large-capacity magazines, requires registration of certain firearms, and restricts open carry in most locations. These Denver ordinances have been subject to legal challenges, with ongoing litigation examining whether they conflict with Colorado state preemption laws.
Other Colorado municipalities have implemented varying levels of firearm restrictions. Some cities prohibit open carry in downtown business districts or public spaces, while others maintain relatively permissive policies aligned with state law. Before carrying a firearm in any Colorado jurisdiction, it’s essential to research local ordinances to ensure compliance. Many county sheriff’s offices and city police departments provide information about local firearm regulations.
State law preemption is an important principle in Colorado gun law, though the extent of preemption has been subject to legal debate. Generally, Colorado law prevents local governments from implementing regulations that are more restrictive than state law in certain areas, but Denver has argued for exceptions to this principle. Consulting local government resources or an attorney familiar with your specific jurisdiction can clarify applicable regulations.
Storage and Safe Handling Requirements
Colorado law does not mandate firearm storage in locked safes or with safety devices, unlike some states that have implemented strict storage requirements. However, gun owners have a legal and ethical responsibility to store firearms safely to prevent unauthorized access, particularly by children or individuals prohibited from possessing firearms. Safe storage practices are important both for legal liability purposes and public safety.
Colorado law does hold gun owners liable if a firearm is negligently stored and subsequently accessed by a minor or prohibited individual who causes harm. This civil liability exposure provides significant incentive for responsible storage practices. Additionally, some homeowner’s insurance policies require specific storage methods as a condition of coverage.
Best practices for firearm storage include using locked safes, gun cabinets, or lockboxes, storing ammunition separately, and using cable locks or chamber locks for additional security. Many firearm retailers and gun ranges in Colorado provide information about storage options and safety practices. Understanding your personal circumstances and the people who have access to your home is important when determining appropriate storage methods.
Colorado also emphasizes safe handling practices through the concealed carry permit process, which includes instruction on firearm safety. Anyone purchasing a firearm should invest in proper safety training from certified instructors. Many Colorado ranges and training facilities offer courses covering firearm safety, legal issues, and shooting proficiency.
Penalties for Non-Compliance
Violating Colorado gun laws can result in significant criminal and civil penalties. Possessing a firearm as a prohibited person—such as a convicted felon or someone subject to a domestic violence protective order—constitutes a felony offense. The specific charge and penalties depend on the nature of the underlying disqualifying factor and the circumstances of the violation.
Transferring a firearm to a prohibited person or failing to conduct a background check when required can result in felony charges and imprisonment. Magazine capacity violations are typically charged as misdemeanors but can carry jail time and substantial fines. Violating an Extreme Risk Protection Order by possessing a firearm can result in contempt of court charges with serious consequences.
Additionally, civil liability exposure exists for gun owners who negligently store firearms or fail to secure them properly. If someone uses your firearm to cause harm, you may face civil lawsuits seeking damages. Understanding the legal consequences of non-compliance should motivate careful adherence to Colorado gun laws and responsible firearm ownership practices.
The specific penalties for various violations are detailed in Colorado’s criminal code, and enforcement varies by jurisdiction. Consulting with an attorney who specializes in firearms law can help you understand the specific consequences of potential violations in your circumstances. Many attorneys offer consultations to discuss gun law compliance and potential legal issues.
