Lawmakers in Connecticut have advanced legislation aimed at banning certain semiautomatic handguns that can be converted into fully automatic weapons. The bill passed the House on an 86 to 64 vote and now moves to the state Senate for consideration. Supporters say the measure targets dangerous conversion devices commonly known as “switches,” while opponents argue it could impact legally owned firearms. If approved, the law would take effect in October and impose penalties for the sale or import of the affected weapons.
