Purchasing a handgun in Colorado is a relatively straightforward process, but there are important legal requirements and restrictions every buyer should know before heading to a licensed dealer.
Whether you’re a first-time gun owner or an experienced buyer, understanding eligibility rules, background checks, and cost expectations can help you navigate the process smoothly.
In this guide, we’ll break down everything you need to know, including who can legally buy a handgun, what disqualifies someone from purchasing, and how much you can expect to pay.
You’ll also learn about Colorado’s firearm laws, processing times, and what to do if your background check is delayed.
Before making a purchase, here’s a quick overview of the key requirements:
- You must be at least 21 years old
- A background check is required (even for private sales)
- Valid identification is necessary
- Certain criminal convictions and restraining orders can disqualify you
- There is no waiting period in Colorado—you can take your handgun home once approved
In the following sections, we’ll cover these points in detail, providing a step-by-step breakdown of the process and what to expect when purchasing a handgun in Colorado.
What is the Minimum Age to Purchase Firearms and Ammunition in Colorado?
According to Public Safety, to buy a handgun in Colorado, you must be a resident of Colorado and at least 21 years old. To purchase a rifle, you must be at least 18 years old, and residency in Colorado is not required. The same age requirements apply to purchasing ammunition [1].
Is There a Waiting Period & Background Check to Purchase Firearms?
There is a waiting period & background check to purchase firearms. This background check is carried out by the Colorado Bureau of Investigation (CBI) and the NICS federal system.
This involves completing an ATF form 4473 and typically takes around twenty minutes for approval, though current high demand can extend this to about three days [2].
The waiting period does not apply to the sale of an antique firearm or a curio or relic; the sale of a firearm by a person serving in the armed forces who will be deployed outside of the United States within the next 30 days to any family member; or a firearm transfer for which a background check is not required pursuant to state or federal law
What Does the CBI Review?
The CBI reviews multiple records to determine if an individual is eligible to own a firearm.
This includes:
- Criminal Record: Any past convictions or pending charges that could prohibit firearm ownership.
- Mental Health Holds: History of involuntary mental health holds that may legally restrict gun ownership.
- Juvenile Delinquency and Probation Records: Colorado law allows access to juvenile records for firearm background checks.
- Federal and State Prohibitions: Verification against all legal restrictions that could prevent the sale from proceeding.
By thoroughly reviewing these records, the CBI ensures compliance with both state and federal laws, helping to prevent firearms from being sold to individuals who are legally prohibited from owning them.
Common Issues and Solutions When Buying a Handgun in Colorado
Purchasing a handgun in Colorado can sometimes be a complicated process, especially if you encounter unexpected delays or legal hurdles. Understanding these common issues and their solutions can help make the process smoother and more efficient.
1. Delays in Background Checks
One of the most frequent problems buyers face is delays in the background check process. While some checks clear within minutes, others may take hours or even days.
Why It Happens:
- Incomplete or incorrect information on the ATF Form 4473.
- High volume of background check requests, especially during peak buying periods.
- Additional review required for individuals with complex records.
How to Solve It:
- Verify your information before submitting the ATF Form 4473 to prevent errors.
- Check with the dealer for updates on your background check status.
- Be patient—Colorado law mandates that the firearm cannot be transferred until the check is complete. If the process takes longer than three business days, contact the Colorado Bureau of Investigation (CBI) for more details.
2. Missing or Incomplete Documentation
Proper documentation is required to complete a firearm purchase, and missing paperwork can lead to unnecessary delays.
Common Missing Documents:
- Valid government-issued ID (such as a Colorado driver’s license).
- Proof of Colorado residency if required.
- Military orders (for service members purchasing in Colorado).
How to Fix It:
- Double-check that you have all necessary identification before heading to the dealer.
- Contact local authorities or the issuing agency to replace lost or missing documents.
3. Purchasing a Handgun from Out of State
Colorado residents may only purchase handguns from dealers within the state. However, some buyers attempt to purchase from another state, which introduces additional legal requirements.
What You Need to Know:
- Handguns purchased out of state must be transferred through a licensed Colorado FFL (Federal Firearms License) dealer.
- You must comply with both Colorado and the state of purchase’s firearm transfer laws.
How to Proceed Legally:
- Use a licensed dealer to ensure compliance with firearm transfer regulations.
- Understand waiting periods and background check procedures in both states before making a purchase.
4. Common Reasons for Background Check Denials
Sometimes, a background check results in a denial, which prevents the sale from proceeding. Understanding why this happens can help you determine whether you are eligible for an appeal.
Top Reasons for Denial:
- Prior felony convictions or active criminal charges.
- Restraining orders or past domestic violence offenses.
- Mental health prohibitions, including involuntary commitments.
- Errors in criminal history records leading to incorrect disqualifications.
How to Resolve It:
- Review firearm eligibility laws to confirm whether you are legally allowed to own a firearm.
- Check for mistakes—if you believe you were denied due to incorrect information, you may be able to correct errors on your record.
5. How to Appeal a Background Check Denial
If you were denied a firearm purchase due to a background check rejection, you have the right to appeal the decision.
Steps to File an Appeal:
- Obtain an appeal form from the gun dealer at the time of denial or request one from the Colorado Bureau of Investigation (CBI).
- Submit the appeal along with any supporting documentation, such as proof of mistaken identity or court documents showing a record has been expunged.
- Wait for review—CBI has up to 30 days to complete the appeal and provide a final decision.
Cost and Processing Time for Background Checks
The cost of a background check in Colorado is set by the CBI and is typically paid by the buyer. This fee is subject to annual appropriation by the state legislature to cover administrative costs.
Payment options vary by dealer but often include cash or card payments.
Processing times can vary depending on demand:
- Typical Time: Background checks are completed in about 20 minutes under normal conditions.
- Extended Time: Some checks may take up to three days or longer if additional review is needed.
In summary, the background check process is an essential step in legally purchasing a firearm in Colorado. While most buyers will receive quick approval, understanding why delays occur, how to appeal a denial, and what costs to expect can help streamline the experience.
If you plan to buy a handgun, being prepared with accurate documentation and knowledge of state regulations will ensure a hassle-free transaction.
What Do I Need to Purchase a Firearm?
According to SCLG, to buy a firearm, you need a valid form of identification, and proof of Colorado residency, and must comply with local regulations [3].
Colorado residents age 21 and over must pass a Colorado Bureau of Investigations (CBI) background check before they can legally purchase a handgun. This requires the buyer to fill out an ATF form 4473 at the gun store. Then the store will submit it to the CBI InstaCheck system
Acceptable IDs include a valid Colorado driver’s license, state ID card, military ID, or a temporary ID with a government-issued photo ID. If your ID does not show your current address, additional proof of residency, such as a DMV registration or hunting/fishing license, is required.
Can Any Colorado ID Be Used for Purchases?
Yes, but if your Colorado ID does not show your current address, you must provide proof of lawful residency with documents like a valid hunting/fishing license, vehicle registration, or a U.S. passport with matching addresses.
I Am in the Military, Can I Buy a Gun? What Do I Need?
Military personnel can purchase firearms with a military ID and current orders showing permanent duty in Colorado. If stationed temporarily or without permanent duty orders, additional proof of residency, like a Colorado driver’s license, is required.
Military personnel have unique circumstances when purchasing firearms, particularly when moving between duty stations or deploying.
Colorado law provides specific allowances for service members while still maintaining federal and state firearm regulations. Understanding these requirements can help ensure compliance and a smooth purchasing process.
Purchasing Firearms as an Active-Duty Service Member
Active-duty military personnel stationed in Colorado can purchase firearms under the following conditions:
- With a Military ID and Permanent Duty Orders: Service members assigned to a permanent duty station in Colorado can use their military ID and current orders as proof of residency. No additional residency documentation is required.
- If Temporarily Stationed: Those stationed in Colorado on a temporary basis must provide additional proof of residency, such as a Colorado driver’s license or lease agreement, to purchase a firearm.
These requirements apply to both handguns and long guns. However, individual dealers may impose their own verification procedures beyond legal requirements.
Firearm Purchases and PCS (Permanent Change of Station) Orders
Military personnel undergoing a Permanent Change of Station (PCS) must follow specific rules when transferring firearms between duty stations:
- Buying a Firearm While in PCS Transition: If a service member is in transition between bases and has not yet established permanent residency at the new duty station, they may face additional requirements depending on the state of relocation.
- Acceptable PCS Documentation: When purchasing in Colorado while in PCS transition, orders that establish Colorado as the new duty station can be used to satisfy residency requirements.
- Interstate Transfers: If a service member is moving to another state and already owns firearms, they must comply with the new state’s firearm laws regarding registration, background checks, and magazine capacity limits.
Deployment Considerations for Firearm Ownership
Service members who own firearms but are deploying overseas or to another location should consider:
- Storage During Deployment: Many military bases offer secure armory storage for personal firearms. Some service members also choose private firearm storage facilities to ensure weapons are kept safely during long-term deployments.
- Legal Transfers Before Deployment: If selling or transferring firearms before deployment, service members must follow federal transfer laws, which generally require the use of a licensed firearm dealer (FFL) to complete the transaction legally.
Special Military Exemptions
Active-duty military personnel are exempt from some firearm laws, including:
- Age Restrictions for Handgun Purchases: Federal law prohibits civilians under 21 years old from purchasing handguns, but active-duty service members stationed in Colorado may purchase a handgun at 18 with valid military ID and orders.
- Background Checks: While most firearm buyers must undergo a Colorado Bureau of Investigation (CBI) background check, some military personnel may qualify for expedited processing due to their security clearances. However, this does not exempt them from background checks entirely.
Rules for Interstate Transfers and Military Relocation
Since service members frequently relocate, understanding interstate firearm transfer rules is important:
- Buying Firearms in a Different State: Military personnel may purchase rifles and shotguns in any state if the sale complies with both the state of purchase and their home state’s laws. However, handgun purchases must generally be made in their state of residence or duty station.
- Shipping Firearms to a New Duty Station: When moving to a new state, service members should check with both their new duty station and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to confirm firearm transport regulations. Firearms must be shipped via FFL if crossing state lines in most cases.
Understanding these military-specific firearm regulations ensures compliance while making the purchase and ownership process as seamless as possible for service members.
What Do I Need for Proof of Residency?
Federal law requires a government-issued ID with a residence address. If your ID shows a P.O. Box or outdated address, provide a second form of government-issued documentation, such as a DMV printout or vehicle registration.
When purchasing a handgun in Colorado, proof of residency is required under federal and state law. While a valid government-issued ID is the primary requirement, additional documentation may be necessary in specific cases. Here’s a detailed breakdown of how residency affects firearm purchases.
Temporary vs. Permanent Residency
- Permanent Residents: Individuals who legally reside in Colorado and hold a Colorado driver’s license or state ID with their current residential address meet residency requirements.
- Temporary Residents: Visitors, seasonal workers, or those staying in the state for short-term reasons (e.g., job assignments, extended family visits) do not qualify as legal residents for handgun purchases.
College Students and Firearm Purchases
College students living in Colorado for school but maintaining residency in another state face unique challenges when purchasing a firearm.
- Students from Out of State: If a student has an out-of-state driver’s license, they cannot purchase a handgun in Colorado unless they establish Colorado residency (e.g., changing their driver’s license to a Colorado ID).
- Students with Colorado Residency: If a student has a Colorado driver’s license and proof of local residency, they may purchase a handgun just like any other state resident.
Multiple Residences and Firearm Purchases
Some individuals maintain multiple residences in different states. Under federal law:
- If a person resides in multiple states during different times of the year, they may be considered a resident of both states while present in each location.
- They may purchase a firearm in either state, provided they show proof of residency at the time of purchase.
Acceptable Residency Documentation Alternatives
If your government-issued ID does not reflect your current address or lists a P.O. Box, you must provide a secondary proof of residence.
Acceptable documents include:
- DMV-issued Address Printout: Obtained from a local DMV office, showing proof of updated residency.
- Vehicle Registration: Must display the applicant’s name and current address.
- Utility Bill: Electric, water, or gas bills in the buyer’s name (cell phone bills do not qualify).
- Rental or Lease Agreement: A signed and current lease listing the buyer’s name as a tenant.
Firearm Purchases After a Recent Move
If you have recently moved to Colorado, you must establish residency before purchasing a handgun. Steps include:
- Updating Your Driver’s License: Colorado law requires new residents to update their license within 30 days of moving.
- Registering a Vehicle in Colorado: If applicable, transferring an out-of-state registration helps confirm your new residency.
- Providing Address Verification: If your ID still lists your old address, use DMV records, utility bills, or a lease agreement as supplemental proof.
By ensuring you meet Colorado’s residency requirements and having the proper documents on hand, you can avoid unnecessary delays in purchasing a handgun.
I Am an Alien. Can I Buy (or Rent) a Gun and/or Ammunition?
Yes, immigrant aliens and those from visa-waiver countries can purchase firearms and ammunition if they meet all other purchase requirements and provide additional documentation, such as an INS-issued Alien Registration Card.
Can I Fill Out the Background Check Ahead of Time?
No, the background check must be completed after selecting a serialized item for purchase or when your out-of-state transfer arrives and is logged into the ATF records.
