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guidance documents, sheriff websites, and court filings — and much of what circulates on forums and social media is outdated or simply wrong.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.
The compliance-cost record exists so that anyone weighing this law — a court, a committee, a reporter, a researcher — can see what it costs the people complying with it.
Who runs it
I'm David Veksler, a Colorado gun owner and software engineer. I got tired of piecing this together from scratch and figured others were too.
My name is on it so that someone is accountable for what it says. I built the site and maintain it on my own time. No organization funds it, directs it, or reviews it before publication.
How the information is kept accurate
The official sources — the state's published guidance, county sheriff pages, court dockets — are checked regularly, and I review every change before it is published. Nothing goes live automatically. Each sourced page ends with one footer showing where its facts came from, when they were checked, and how they were verified. If something can't be confirmed, it is labeled that way rather than presented as fact.
