To answer your original question, as best as I can determine, it is legal to own and carry a stun gun for self defense purposes in Texas.

If I were you, I would get a Taser rather than a stun gun because you have some stand off ability with a Taser whereas with a stun gun you have to be in contact distance. Given what you have said about your husband, you may find the stun gun being used against you.

As another poster said, continue to call the police everytime something happens. They may not do anything but you are laying a paper trail that would be really helpful if you ever have to shoot him or knife him to protect yourself.
