OK. It is not illegal to walk down the street with a Long GUN visible, As long as you are not displaying it in a manner calculated to alarm. Unless you meet the requirments of Penal Code 46.02 or 46.15 (b) you cannot carry a handgun without a CHL, and then it must be concealed. Texas does not generally address the loaded or unloaded status of firearms for carry.It's actually not illegal to walk down the street with an unloaded weapon as long as you're not "brandishing it in a threatening manner".
If the police cannot arrest you they have no authority to make you take it anywhere.You'll probably get some funny looks and I imagine someone will call the cops, but the worst that can legally happen is that the police will tell you to take it home.
If the police have PC to believe you were displaying the firarm in a manner calculated to alarm then they can arrest you, whether or not the firearm is loaded.
