Gov. Jared Polis (D-CO) signed a new gun bill into law that would add several steps to legally purchase a firearm in Colorado.

The legislation will make it illegal to purchase, sell, or make certain semiautomatic firearms without a permit from a local sheriff, completing a firearm training course, and passing background checks. Polis said in a statement upon signing the legislation that he believes it will uphold Second Amendment gun rights and improve public safety in the Centennial State.
