Despite its Democratic-controlled legislature, Colorado has rejected a bill that would ban the sale and transfer of semi-automatic firearms. However, the state is moving forward with other gun control measures, including proposals to increase taxes on gun and ammunition sales, expand background checks, and require firearm dealers to obtain state permits. Supporters of the semi-automatic ban argue that it is a necessary step to reduce gun violence, while opponents question its effectiveness and assert that it infringes on Second Amendment rights.
