Colorado's New Semiautomatic Firearm Purchase Rules Are Now in Effect

Buying many detachable-magazine semi-automatic firearms now requires a county-issued card, state-approved training, and a separate dealer verification step.

Colorado's new purchase system for many semi-automatic firearms is now live. As of August 1, 2026, buyers and recipients of firearms that the state calls "specified semiautomatic firearms," or SSFs, generally need a county-issued eligibility card and a state-approved training record before a dealer can proceed with the ordinary sale or transfer process.

That is the practical development here. Senate Bill 25-003 became law in April 2025, but its central purchase and transfer provisions did not take effect until this weekend. Colorado Parks and Wildlife has since opened the Firearms Safety System, published the five-step buyer process, set its record fee, and begun listing approved instructors. Anyone contemplating a covered purchase now has more than statutory language to work with, although the rollout is not uniform across every county.

What Colorado Calls an SSF

The law's category is broad, but it is not a blanket definition of every semi-automatic firearm. It covers a semi-automatic rifle or shotgun that accepts a detachable magazine. It also covers a gas-operated semi-automatic handgun with a detachable magazine.

That last distinction matters. The statute excludes recoil-operated semi-automatic handguns that use single-action, double-action, or a combination of those operating systems. It also excludes manually operated firearms; firearms rendered permanently inoperable; antiques and curios or relics; and firearms with a permanently fixed magazine holding no more than 15 rounds. The enacted law names several additional models and families that are excluded as configured on the effective date.

Model-by-model calls may still get messy. Colorado requires its Firearms Dealer Division to publish guidance on specific firearms, and the state says that guidance is not all-inclusive. New models can be added after review. A buyer, dealer, or manufacturer may petition the division for a statement of position on a particular firearm. In other words, "it looks exempt to me" is not much of a compliance strategy.

The operative restrictions concern knowingly manufacturing, distributing, transferring, selling, or purchasing a covered SSF on or after August 1 unless an exception applies. The General Assembly's enacted-bill summary lists exemptions for certain government, military, gunsmithing, educational, museum, inheritance, and film-production transactions. The training route is the one most ordinary retail buyers will encounter.

The Five-Step Purchase Route

The state process starts before the prospective buyer visits an instructor. First, the applicant creates an account in the Firearms Safety System and submits an application. Existing hunter-education information goes into the application at this stage.

Next comes the county sheriff. The applicant must provide a government-issued photo ID and a name-based background check in the form required by the local office. The sheriff reviews the application and decides whether to issue a firearms course eligibility card. If approved, the card is entered into the system and remains valid for five years.

There is already a practical snag: CPW warns that some counties did not plan to review applications until August 1, while others were not accepting applications at all. The agency tells applicants to contact their county sheriff before submitting anything. That makes the buyer's county, not merely the statute, an early stop in planning the transaction.

Only after receiving the card does the applicant enroll with a verified Firearms Safety Program instructor. The course depends on the applicant's training history. A person with CPW-certified hunter education takes the four-hour basic course. Someone without qualifying hunter education generally takes the 12-hour extended course, which must be conducted over at least two days.

Neither a concealed-handgun course nor another generic firearms class substitutes for this program. CPW specifically says concealed-carry background checks and training are not reciprocal. Out-of-state hunter education must be CPW-certified, and the applicant must have the credentials verified in Colorado's records.

Both versions are in-person courses. Students must pass a final examination and a hands-on practical with a score of at least 90 percent. The published curriculum includes safe handling of semi-automatic firearms and magazines, child safety, safe storage, extreme-risk protection orders, mental-health-related firearm deaths, and victim awareness, among other topics. The instructor records pass or fail in the state system; CPW says instructors have up to three business days to enter extended-course results.

Passing does not complete a firearm sale. It establishes eligibility to purchase covered firearms for five years. At the dealer, the FFL checks the Firearms Safety System and, if the buyer qualifies, begins the normal purchase process. The usual federal and state transfer requirements still apply.

The Bill Is More Than a Class Fee

Colorado's record fee is $52, collected by the sheriff and forwarded to CPW. That is only one part of the cost. Each sheriff may assess a separate administrative fee, and private instructors set their own course prices. CPW says the application fees are charged even if the sheriff denies the application.

Time may be the larger burden. A first-time applicant without qualifying hunter education needs the online application, the sheriff's process, a 12-hour course held on at least two days, a passing score, and entry of that result before an FFL can verify eligibility. Instructor availability and county participation will determine whether this is merely inconvenient or a substantial delay in a given part of the state.

The eligibility card and successful course record are both tied to five-year windows. CPW's public instructions say that after five years, the buyer must restart at the application stage. The statute contains a refresher path for people whose extended course is older than five years, but buyers should use the current state instructions and confirm their status before arranging a transfer.

The criminal stakes are not trivial. The General Assembly summarizes a first unlawful manufacture, distribution, transfer, sale, or purchase as a class 2 misdemeanor and a second or subsequent offense as a class 6 felony. A qualifying misdemeanor conviction can also lead the Colorado Bureau of Investigation to deny firearm transfers for five years. Dealers face state-permit consequences for unlawful transactions. Those are good reasons for both sides of a sale to resolve uncertain classifications before money changes hands.

What Changed, and What Did Not

CPW says the August 1 provisions apply to purchases and transfers occurring on or after that date. The agency's implementation material distinguishes the new process from a registry of firearms already owned: the system records cards, training, and purchase eligibility, not a list of an individual's guns. The purchase section does not direct existing owners to apply for a card simply to keep or use a covered firearm.

The same act also changed Colorado law concerning large-capacity magazines and devices designed to increase a semi-automatic firearm's rate of fire. Those provisions are separate from the training-and-card route and deserve separate treatment. A buyer should not assume that course eligibility makes every magazine, accessory, configuration, or local transfer lawful.

Colorado gun owners also have to account for local rules and any later court orders or agency revisions. State guidance can change as officials classify more firearms and counties settle on their procedures. This article is a summary of the system at launch, not legal advice.

The clearest takeaway is mundane but important: for a covered retail purchase, going straight to the gun counter is now several steps too late. Start with the CPW SSF page, check with the county sheriff, verify the exact firearm's status, and locate an approved instructor. Colorado has turned what was once a conventional transfer into a credentialed process, and the first weeks will show how well that process works outside a flowchart.
