Colorado lawmakers introduce hundreds of bills each year. Bills in Brief cuts through the noise by explaining which proposals matter, what’s at stake, and how decisions at the Capitol could affect everyday life across the state.

Numerous gun-related bills are already moving through the Colorado legislature just weeks into the 2026 session, with proposals ranging from expanding who could petition to temporarily someone’s gun to rolling back existing firearms laws.

The first bill of the session seeks to expand who can file for an extreme risk protection order to prohibit individuals who poss a “significant risk” to themself or others from purchasing or possessing a firearm.

Senate Bill 004, sponsored by Sens. Julie Gonzales, D-Denver, and Tom Sullivan, D-Centennial, expands that ability to health care and educational facilities. It passed through the Senate and will be heard by the House State, Civic, Military and Veterans Affairs Committee on March 2.
