Colorado’s 2026 legislative session has officially concluded, and much of the attention from Colorado gun owners is now shifting toward the implementation of SB25-003 and what it could mean for future firearm purchases in the state.
Over the past two weeks, several major federal firearm developments have created a sharp contrast between the direction of federal regulators and the direction Colorado lawmakers continue to pursue. The U.S. Department of Justice recently filed lawsuits challenging both Colorado’s 15-round magazine restriction and Denver’s AR-style rifle ban. At the same time, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) announced one of the largest firearm regulatory reform efforts in years, including proposals to repeal the controversial pistol brace rule and reduce several regulatory burdens affecting firearm owners and dealers.
In simple terms, federal regulators appear to be easing pressure on firearm ownership and compliance requirements while Colorado continues moving toward additional restrictions and expanded oversight.
Beginning August 1, 2026, SB25-003 is expected to introduce additional training and compliance requirements before many semiautomatic firearms with detachable magazines can be purchased in Colorado. Current implementation plans involve new firearm safety training standards, additional eligibility requirements, and expanded compliance procedures that are still being finalized by state agencies.
For Colorado gun owners, this creates an environment where understanding current firearm laws and staying informed is becoming increasingly important. While federal agencies are reconsidering or rolling back several nationwide firearm regulations, Colorado’s firearm laws continue evolving in the opposite direction.
At Damage Factory, we believe informed and responsible firearm ownership starts with education, training, and understanding the laws before they affect you. As Colorado gun laws continue changing, we will continue doing our best to provide updates, training opportunities, and straightforward information for Colorado firearm owners without the political noise or unnecessary confusion.

What Is SB25-003?
SB25-003 is a Colorado firearm law scheduled to begin implementation on August 1, 2026. The law creates additional training, eligibility, and compliance requirements before many semiautomatic firearms with detachable magazines can be purchased in Colorado.
Under the current framework, firearm purchasers may be required to complete state-approved firearm safety training and meet additional documentation requirements before purchasing certain firearms. Colorado agencies are still finalizing portions of the implementation process, which means guidance and procedures may continue evolving over time.
Many Colorado gun owners, firearm instructors, dealers, and legal observers expect SB25-003 to significantly change the firearm purchasing process throughout the state.
How DOJ Lawsuits Could Affect Colorado Gun Owners
The U.S. Department of Justice recently filed lawsuits challenging both Colorado’s 15-round magazine restriction and Denver’s AR-style rifle ban. These lawsuits argue that commonly owned firearms and magazines may be protected under the Second Amendment.
If successful, these cases could impact how courts evaluate firearm restrictions in Colorado moving forward. However, legal challenges often take months or years to fully resolve, and existing Colorado firearm laws generally remain enforceable while litigation continues.
For Colorado gun owners, this means there is currently a growing conflict between federal legal challenges and Colorado’s ongoing efforts to expand firearm restrictions and compliance requirements.
ATF Rule Changes and Pistol Brace Updates
In April 2026, the ATF announced one of the largest firearm regulatory reform packages in recent years. The proposals include reducing several regulatory burdens affecting firearm owners, simplifying certain compliance processes, and proposing repeal of the controversial pistol brace rule.
The pistol brace rule previously attempted to classify many braced pistols as short-barreled rifles under the National Firearms Act (NFA), creating confusion and legal challenges nationwide. Multiple federal court decisions questioned the legality of the rule, and the ATF is now proposing to formally repeal it.
Additional ATF proposals also include modernization efforts involving electronic filing systems and possible simplification of interstate transport rules for some NFA-regulated firearms.
What Colorado Gun Owners Should Do Now
Colorado firearm laws are changing quickly, and staying informed is becoming increasingly important for responsible firearm ownership.
Colorado gun owners should:
- Stay updated on SB25-003 implementation timelines
- Understand current Colorado magazine and firearm restrictions
- Follow ongoing DOJ and ATF legal developments
- Complete firearm safety and training courses early
- Verify firearm laws before making purchases or traveling
At Damage Factory, we strongly encourage Colorado firearm owners to stay educated, continue training regularly, and understand the law before future regulatory changes take effect. Join our private range membership for at little as $30/month.
