In the years since the Aurora shooting, Colorado has required that firearms be stored securely to prevent child access, ensured domestic abusers turn in their guns, and mandated background checks for all gun sales. In 2021 alone, lawmakers in the Centennial State repealed a law limiting localities from passing gun laws, created an Office of Gun Violence Prevention, barred people with violent offenses from buying guns, and limited qualified immunity. In 2023, lawmakers continued their progress by passing laws to help hold bad actors in the gun industry accountable for the harms they cause, raise the age to purchase a firearm, stem the proliferation of ghost guns, and institute a waiting period for firearm sales. 2024 was another banner year for Colorado: the state enacted many new gun safety laws including an excise tax on all firearms and ammunition to support essential services and a gun dealer licensing system.
