Understanding Colorado's SB 25-003 Law: What Gun Owners Need to Know
Colorado's SB 25-003 created new firearm safety training requirements. Here's what the law actually says, who it affects, and how to comply.
Colorado's Senate Bill 25-003 introduced new firearm safety training requirements that affect gun owners across the state. If you've heard about this law but aren't sure what it actually requires — or whether it applies to you — this breakdown covers everything you need to know.
What Is SB 25-003?
Senate Bill 25-003 is Colorado legislation that establishes mandatory firearm safety training requirements for certain categories of gun owners. The law was designed to reduce firearm accidents and promote responsible ownership through standardized education.
The bill created a state-approved curriculum that covers safe storage, handling, and the legal responsibilities that come with owning a firearm in Colorado.
Who Does SB 25-003 Apply To?
The law applies to individuals who fall into specific categories defined by the legislation. If you are unsure whether the law applies to your situation, consulting with a qualified firearms instructor or legal professional is the best course of action.
PG Firearms Training's SB 25-003 course is designed to meet the state's requirements and is taught by active law enforcement officers who can answer your questions about compliance.
What Does the Training Cover?
The SB 25-003 curriculum is divided into two course options depending on your needs:
Basic Course — 4 Hours ($125)
The Basic course covers the foundational requirements of the law:
- Safe storage — Colorado's requirements for storing firearms to prevent unauthorized access, particularly by minors
- Safe handling fundamentals — the four rules of firearm safety and proper handling practices
- Colorado firearm law overview — your rights and responsibilities as a gun owner under state law
- Accident prevention — common causes of firearm accidents and how to avoid them
This course satisfies the SB 25-003 requirement for most gun owners.
Extended Course — 12 Hours ($199)
The Extended course goes significantly deeper and is ideal for gun owners who want comprehensive training beyond the minimum requirement:
- Everything in the Basic course
- Hands-on firearm handling — practical instruction with your firearm
- Use-of-force law — when deadly force is legally justified in Colorado
- Situational awareness — recognizing and avoiding dangerous situations
- Advanced safe storage — biometric safes, quick-access options, and best practices for households with children
The Extended course is also a strong foundation for anyone considering applying for a Colorado CHP in the future.
Safe Storage: A Key Focus of the Law
One of the most important components of SB 25-003 is its emphasis on safe storage. Colorado law requires that firearms be stored in a way that prevents access by unauthorized individuals — particularly children.
The training covers:
- Locking devices — trigger locks, cable locks, and their proper use
- Gun safes and lock boxes — what to look for and how to use them correctly
- Quick-access options for home defense firearms
- The legal consequences of improper storage if a minor accesses your firearm
This isn't just about legal compliance — it's about preventing tragedies. Proper storage is one of the most impactful things a gun owner can do.

- Book your class — PG Firearms Training offers both options with regular scheduling throughout the Denver metro area
