Colorado Gun Laws 2026: The New Semi-Automatic Purchase Requirements Explained

Colorado enacted one of the most significant changes to its firearms purchasing process in recent history. Starting August 1, 2026, buyers of certain semi-automatic firearms must present a Firearms Safety Course Eligibility Card (FSCEC) at the point of sale. If you plan to purchase a covered firearm in Colorado, understanding this requirement before you visit a dealer will save you time and prevent an incomplete transaction.

What Is the Firearms Safety Course Eligibility Card?

The Firearms Safety Course Eligibility Card is a state-issued document confirming that the holder has completed a state-approved firearms safety course. It is not a license to carry or a permit — it is a purchase eligibility document specific to covered semi-automatic firearms.

To obtain the card, buyers must:

1. Complete a state-approved firearms safety course from a certified instructor 2. Submit proof of course completion to the Colorado Bureau of Investigation (CBI) or the relevant issuing authority 3. Receive the card by mail or through the designated portal

The course curriculum covers safe storage, basic operation, legal responsibilities, and handling procedures. Courses vary in length but are generally expected to run between three and eight hours depending on the provider and format.

**Cost:** Course fees are set by individual providers. The state has worked to keep courses accessible, but prices will vary by instructor and region. The card itself carries a separate state processing fee. Check the Colorado Bureau of Investigation website for current fee schedules.

**Timeline:** Processing times for the card after course completion may take several weeks during peak demand periods. If you are planning a purchase, begin the process well before your intended transaction date.

**Validity:** The card has a defined validity period. Purchasers should confirm the current expiration window with the issuing authority, as regulations may set a renewal schedule.

Which Firearms Require the Eligibility Card?

The requirement applies to "covered" semi-automatic firearms as defined under Colorado law. The definition encompasses:

- Semi-automatic centerfire rifles with detachable magazines - Semi-automatic pistols with detachable magazines above a specified capacity threshold - Semi-automatic shotguns with detachable magazines

The law includes firearms meeting certain feature criteria. Dealers are required to determine whether a specific model falls under the covered definition. When in doubt, ask your licensed dealer to confirm before beginning the purchase process.

**What is not covered:**

The following categories are generally exempt from the eligibility card requirement:

- **Bolt-action rifles** — manually cycled, not semi-automatic - **Lever-action rifles** — manually cycled - **Pump-action shotguns** — manually cycled - **Revolvers** — the cylinder indexes manually or via double-action mechanism, not a semi-automatic action - **Single-shot firearms** — any configuration - **Semi-automatic rimfire rifles** of certain configurations (verify specific exclusions with your dealer)

If you are purchasing a manually operated firearm, the eligibility card does not apply to your transaction.

The Background Check Still Applies

The Firearms Safety Course Eligibility Card does not replace the federal background check. They are separate, parallel requirements.

When purchasing from a licensed dealer in Colorado, you will still complete:

- **ATF Form 4473** (Firearms Transaction Record) - **NICS background check** conducted through the Colorado Bureau of Investigation, which serves as the state point of contact

Colorado is a point-of-contact state, meaning the dealer contacts CBI rather than the FBI directly. CBI then queries NICS and state-level records. Approval, delay, or denial responses follow the same process as before.

Both the eligibility card and the background check must be satisfied for the transaction to proceed. A cleared background check does not substitute for a missing eligibility card, and vice versa.

Magazine Capacity Limits

Colorado limits magazine capacity to 15 rounds. This limit has been in place since 2013 and applies to both rifles and handguns. Magazines manufactured or purchased in the state after the effective date of the original law must not exceed 15 rounds.

Magazines with a capacity greater than 15 rounds that were legally owned before the original 2013 cutoff date may be retained, but their legal status for new purchases or transfers should be verified with a licensed attorney familiar with Colorado firearms law.

The 2026 changes to semi-automatic purchase requirements do not alter the existing 15-round magazine limit.

Red Flag Law

Colorado's Extreme Risk Protection Order (ERPO) law, commonly called the red flag law, remains in effect. Under this law, a court may issue an order requiring a person to surrender firearms if a petition demonstrates that the person poses a significant risk of harm to themselves or others.

Petitions can be filed by law enforcement, family members, or household members. The process involves an initial hearing and a follow-up hearing where the subject may contest the order. The law is civil rather than criminal in nature at the petition stage.

The ERPO law operates independently of the eligibility card requirement.

Age Requirements

Colorado requires purchasers of handguns to be at least 21 years of age when buying from a licensed dealer. This mirrors federal law.

For long guns (rifles and shotguns), federal law sets the minimum age at 18 for purchases from licensed dealers. Colorado-specific provisions may affect this — confirm current state age requirements with your dealer or an attorney, as additional state-level changes may be enacted.

The eligibility card requirement applies regardless of age, meaning buyers who meet the age threshold must still complete the safety course and obtain the card before purchasing a covered semi-automatic firearm.

Where to Complete the Safety Course

Courses must be offered by state-approved instructors and programs. Approved providers may include:

- Firearm retailers with certified instructors on staff - Independent NRA-certified or USCCA-certified instructors who have obtained state approval under the new rules - Range facilities offering group courses - Online course formats (availability depends on state approval of specific online providers)

The Colorado Bureau of Investigation and the relevant state agency administering the FSCEC program will maintain a list of approved providers. Check those official sources for current listings rather than relying on third-party directories, as approvals may change.

Practical Steps for Colorado Buyers in 2026

If you intend to purchase a covered semi-automatic firearm in Colorado, the sequence is:

1. Confirm your intended firearm is covered (ask your dealer) 2. Find a state-approved safety course provider 3. Complete the course 4. Submit your completion documentation and obtain your eligibility card 5. Allow for processing time 6. Visit a licensed dealer with your eligibility card 7. Complete ATF Form 4473 and the NICS background check as normal 8. Complete the purchase

Dealers may not substitute any other document for the official eligibility card. Arriving at a dealer without the card for a covered firearm will result in the transaction not proceeding.
