Below is the part of the statute dealing with where you cannot legally carry a concealed handgun under authority of your license. I think Texas law is superior in effect in some cases, but Missouri is far easier to figure out. One important clause that appears in nearly every prohibition: "Possession of a firearm in a vehicle on the premises of [a prohibited place] shall not be a criminal offense so long as the firearm is not removed from the vehicle or brandished while the vehicle is on the premises."
Also of interest: "Carrying of a concealed firearm in a location specified in subdivisions (1) to (17) of subsection 1 of this section [i.e. any prohibited location] by any individual who holds a concealed carry endorsement issued pursuant to sections 571.101 to 571.121 shall not be a criminal act but may subject the person to denial to the premises or removal from the premises.
