The 2025 Colorado General Assembly wrapped yesterday, capping a record-breaking year for gun violence prevention measures at the Capitol. In all, 12 new bills were passed. One Ceasefire-endorsed bill was defeated, as were three ‘bad’ bills we strongly opposed.
The biggest news was the passage of SB25-003, Semiautomatics High Capacity Magazine Ban Enforcement (Sens. Tom Sullivan and Julie Gonzales/Reps. Andrew Boesenecker and Meg Froelich), which bans the sale of most semi-automatic firearms that accept detachable magazines and classifies rapid-fire guns as dangerous weapons. The bill was amended to exempt someone who has taken an extended firearm safety class. It was signed by Gov. Jared Polis April 10 and becomes effective Aug. 1, 2026.
Also already signed into law are the following:
SB25-059 Support for State Response to Mass Shootings (Sen. Tom Sullivan/Reps. Steven Woodrow and Michael Carter), which requires the Division of Criminal Justice to apply for and expend federal and other grant money to improve the state’s response to mass shootings and support services for victims. It was signed by Gov. Polis on April 10 and becomes effective Aug. 5, 2025.
HB25-1133 Requirements for Sale of Firearms Ammunition (Reps. Monica Duran and Lindsay Gilchrist/Sens. Judy Amabile and Cathy Kipp), which establishes requirements for the storage of
ammunition and delivery of ammunition sold at retail. It was signed by Gov. Polis on April 18 and becomes effective July 1, 2026.
HB25-1238 Gun Show Requirements (Sens. Lisa Frizell and Lindsey Daugherty/Reps. Andrew Boesenecker and Anthony Hartsook), which requires specific safety procedures by promoters including a safety plan, monitoring of main entrances and exits, posting signs, and obtaining certification from vendors that they will comply with (often ignored) federal, state, and local laws. It was signed by Gov. Polis on April 18 and becomes effective January 1, 2026.
Colorado Ceasefire also supported the following bills, which passed both chambers but have not yet been signed by the Governor:
SB25-034 Voluntary No Buy (Sen. Cathy Kipp and Rep. Andrew Boesenecker), which allows a person to voluntarily put themselves on the NICS no buy list.
SB25-158 Procurement (Sens. Tom Sullivan and Julie Gonzales/Reps. Meg Froelich and Kyle Brown), which Requires that firearms acquired by state agencies are purchased from responsible dealers.
SB25-205 Firearm Serial Number Check (Sen. Nick Hinrichsen/Reps. Cecelia Espenoza and William Lindstedt), which Allows FFLs to request a check on a firearm serial number for a gun before purchase from an individual. Sheriffs are to do the check in 72 hours or return the fee, and FFLs, in turn, must report to law enforcement within 48 hours any such attempted purchase for which the gun was reported lost, stolen or involved in a criminal investigation.
HB25-1062 Penalty for Firearm Theft (Reps. Ryan Armagost and Monica Duran/Sens. Nick Hinrichsen and Byron Pelton), which makes theft of a firearm a Class 6 felony; second offense is Class 5 felony.
HB25-1098 Automated Protection Orders (Reps. Rebecca Stewart and Matt Soper/Sen. Dafna Michaelson Jenet), which provides a system of notifying a domestic violence victim of certain actions, including when the abuser has attempted to purchase a gun. Fiscal restraints are that funding must come from grants, and the program cannot begin until funding for one year has been obtained.
HB25-1171 POWPO for Vehicle Theft (Reps. Shannon Bird and Andrew Boesenecker/Sen. Nick Hinrichsen), which adds motor vehicle theft to the list of felonies that prohibit the possession of a firearm by a previous offender (POWPO).
HB25-1250 Gun Violence Prevention and Parents of Students (Reps. Eliza Hamrick and Duran/Sen. Lisa Cutter), which requires the State’s Office of Gun Violence Prevention to post on its website materials on gun violence prevention and for local education providers to distribute this information, either electronically or written, to each parent of students in K-12.
Also passed and waiting on Polis’s signature is HB25-1225 Freedom from Election Intimidation (Reps. Steven Woodrow and Elizabeth Velasco/Sen. Nick Hinrichsen and Lindsey Daugherty), which prohibits an individual from intimidating, threatening or coercing someone in election activities. Persons who carry firearms, imitation firearms or toy firearms are presumed to be engaged in intimidation. The bill provides for lawsuits by elected officials or individuals. Colorado Ceasefire was neutral on this bill.
Defeated in this year’s session were a number of Gun Lobby-backed ‘bad’ bills, which Ceasefire worked against. These bills would have wiped out much of the amazing progress Colorado gun violence prevention advocates have made in recent years:
HB25-1055 Repeal Gun Dealer Permitting (Rep. Max Brooks), which said the dealer permitting established in 2024 is unnecessarily burdensome on gun dealers and, in some cases, duplicative of federal law.
HB25-1164 Permitless Concealed Carry (Rep. Ron Weinberg), which would have allowed anyone to carry a concealed handgun without a permit. A bill of this sort has been defeated for 12 consecutive years (14 bills), but this bill had much more: It changed the age to carry concealed to 18 with or without a permit; extended permit from five years to lifetime; wiped out parts of the 2024 Safe Spaces bill; wiped out part of the 2024 CCW training classes bill; and overturned the preemption repeal of 2024 with regard to CCW and open carry.
HB25-1232 Liability When Means of Self Defense Prohibited (Rep. Stephanie Luck) which made the owner in control of a property who prohibits persons bringing arms of self-defense onto the property liable for damages for harm suffered by a person who could have defended themself with firearms.
Colorado Ceasefire was neutral on another failed bill, HB25-1128 Income Tax Credit for Firearm Safety Device (Reps. Ceclia Espenoza, Sen. Kyle Mullica) Which created an income tax credit for the purchase of a device capable of locking and storing firearms.
All in all, an amazing year of progress for people who want to keep Coloradans safe where they live, work and play. As always, thank you for your support in helping make these victories possible!
