However, if the firearm is displayed in a manner ``calculated to cause alarm,'' then it is ``disorderly conduct''. Open carry of a handgun in public had long been illegal in Texas, except when the carrier was on property he/she owned or had lawful control over, was legally hunting, or was participating in some gun-related public event such as a gun show. However, the 2015 Texas Legislature passed a bill to allow concealed handgun permit holders to begin carrying handguns openly. The bill was signed into law on June 13, 2015, and took effect on January 1, 2016. A License to Carry (LTC) is still required to carry a handgun openly or concealed in public.
