About this site
Why this site exists
Colorado's specified-semiautomatic-firearms law (SB25-003) is hard to follow, even for people trying in good faith to comply with it. The state's list of covered models changes over time. Each of Colorado's 64 counties is working out its own approach to eligibility cards, with different fees, timelines, and procedures. The answers are scattered across state guidance documents, sheriff websites, and court filings — and much of what circulates on forums and social media is outdated or simply wrong.
This site puts those answers in one place: what the current list says, what changed between versions, what your county is actually doing, and where each piece of information came from. It is a reference, not an advocacy organization. It does not lobby, endorse candidates, or take a position on the law.
Who runs it
A Colorado gun owner and software engineer who got tired of piecing this together from scratch and figured others were too.
How the information is kept accurate
The official sources — the state's published guidance, county sheriff pages, court dockets — are checked regularly, and a person reviews every change before it is published. Nothing goes live automatically. Every fact on the site shows where it came from, when it was last checked, and how it was verified. If something can't be confirmed, it is labeled that way rather than presented as fact.
