If I'm not mistaken, this is amending the section that makes it illegal for someone without an LTC to openly carry a firearm in their car. Currently the MPA only allows for concealed carry in a vehicle for those without a license to carry.
Incorrect. This amends Texas Penal Code 46.035 (a) which is only applicable to an LTC holder.
Sec. 46.035. UNLAWFUL CARRYING OF HANDGUN BY LICENSE HOLDER
