In a series of significant votes, the Colorado House of Representatives has passed multiple bills aimed at tightening gun control in the state. Key measures include a controversial semiautomatic firearm restriction bill and legislation that mandates safety training for certain firearm purchases. After extensive debate, including a 12-hour session, lawmakers approved a ban on detachable magazines, while also moving forward with bills regulating ammunition sales and gun shows. The measures, backed by Democratic leaders, have sparked fierce debates with Republican lawmakers and have drawn mixed responses from gun owners. These developments are part of a broader effort in the legislature to enhance safety and address concerns over mass shootings.
