Missouri state lawmakers repealed the PTP law in 2007, and most remaining gun-purchase checks and regulations fell like legislative dominoes in the years thereafter. As noted earlier, 2014 legislation allowed anyone with a concealed weapons permit to carry guns openly in cities or towns that otherwise banned the open carrying of firearms. In 2016, the Missouri legislature passed “permitless carry” legislation, created new “stand-your-ground” laws, and expanded Castle Doctrine protections.
