Denver, CO – In a landmark move to enhance public safety, Colorado Governor Jared Polis has signed into law Senate Bill 25-003, introducing one of the state’s most comprehensive gun regulations in recent years. The bill imposes sweeping restrictions on the sale and use of semiautomatic firearms with detachable magazines, aiming to reduce gun violence across the state.
This measure, which has been met with both praise and criticism, marks a significant moment in Colorado’s ongoing efforts to address firearm-related concerns.
Key Provisions of the Semiautomatic Firearm Ban
The new law includes several provisions aimed at regulating semiautomatic firearms and ensuring safer ownership practices:
- Purchase Requirements: Starting August 1, 2026, individuals looking to purchase certain semiautomatic firearms must first complete a state-certified safety course and pass a background check. These requirements aim to ensure responsible ownership and prevent the purchase of firearms by those with a history of violent crimes or mental health issues.
- Mandatory Firearm Safety Courses: The law mandates that all new firearm buyers undergo training that covers proper firearm handling, relevant state and federal firearm laws, and crisis intervention strategies. The course is designed to ensure that individuals not only understand how to operate a firearm safely but are also equipped to handle situations that could otherwise escalate into violence.
- Ban on Specific Firearms: The legislation targets semiautomatic rifles, handguns, and shotguns that are capable of accepting detachable magazines. This includes popular models such as the AR-15 and AK-47, which have been involved in numerous mass shootings across the country. The law also bans the sale of rapid-fire devices like bump stocks, which allow semiautomatic firearms to function like automatic weapons.
- Exemptions for Existing Owners: Current firearm owners are not required to surrender their semiautomatic firearms. The law only affects new purchases or transfers of specified weapons post-enactment. Those who already own the targeted firearms will not face retroactive restrictions.
- Prohibition of “Ghost Guns”: The law also addresses the rising threat of “ghost guns” – firearms assembled from kits that lack serial numbers, making them untraceable. The bill requires manufacturers and dealers to register such firearms and impose restrictions on their sale.
Governor Polis’s Statement on the Law
Governor Jared Polis, who signed the bill into law, expressed his support for stronger gun control while emphasizing the importance of balancing safety with constitutional rights. “While it’s vital to respect the Second Amendment, it’s equally important to take action to reduce gun violence,” Polis said.
“This law strikes a reasonable balance that ensures the rights of law-abiding citizens while helping protect our communities from dangerous weapons.”
In his statement, Polis reiterated that this measure does not amount to a complete ban on firearms. “This is about responsible ownership, ensuring that those who wish to own firearms are doing so safely and in accordance with the law.”
The governor’s office also stressed that the legislation would help save lives by addressing the ongoing gun violence crisis in Colorado. Polis pointed to the state’s history of mass shootings, including the 1999 Columbine High School massacre and the more recent 2022 Club Q shooting in Colorado Springs, which prompted widespread calls for stronger gun regulations.
Support and Opposition to the Legislation
The bill has received mixed reactions from different political factions and advocacy groups. Supporters of the law, including state legislators and public safety advocates, argue that it is a necessary step to curb the growing threat of mass shootings.
Senator Tom Sullivan, one of the bill’s primary sponsors, expressed his belief that the law would help protect communities from gun violence. Sullivan, who lost his son in the 2013 Aurora theater shooting, has long been a proponent of stricter gun control measures in the state.
“We can’t afford to wait any longer to address the ongoing impact of gun violence in our communities,” Sullivan said. “This law is a step toward making Colorado safer for everyone.”
However, critics of the bill, including some Republican lawmakers and pro-gun advocacy groups, have expressed concerns about its potential to infringe on Second Amendment rights.
Groups like the National Rifle Association (NRA) and Rocky Mountain Gun Owners have strongly opposed the legislation, arguing that it imposes unnecessary burdens on responsible gun owners.
“The law is an overreach and infringes on the rights of Coloradans,” said Dudley Brown, executive director of Rocky Mountain Gun Owners. “It effectively bans popular firearms that law-abiding citizens have the right to own and use.”
In particular, opponents are concerned about the extensive training requirements and the potential for legal challenges. They argue that the law may unintentionally criminalize lawful firearm owners, making it harder for them to exercise their rights.
Colorado’s History of Gun Violence and Legislation
Colorado has long been a focal point in the national debate over gun control, largely due to its history of mass shootings. The Columbine High School shooting in 1999 was one of the deadliest school shootings in U.S. history and sparked nationwide discussions on gun laws.
More recently, the 2012 Aurora theater shooting and the 2022 shooting at Club Q in Colorado Springs have further fueled calls for stricter gun regulations.
The new law is part of a broader trend in Colorado and other states to address gun violence through legislation. Several other states have passed laws that require background checks, mandatory safety courses, and restrictions on high-capacity firearms. Colorado now joins states like California and New York in implementing stricter firearm regulations.
Conclusion
Governor Polis’s signing of Senate Bill 25-003 represents a significant step forward in Colorado’s efforts to reduce gun violence while maintaining a respect for the constitutional rights of gun owners. While the law’s impact remains to be seen, it signals a growing commitment to public safety in the wake of numerous mass shootings in the state.
As the law goes into effect in 2026, Colorado residents and firearm dealers will need to adapt to these new regulations, which are intended to promote responsible firearm ownership and reduce the risks associated with semiautomatic weapons.
