This made me curious about what the Texas state constitution had for an equivalent to the 2nd amendment. Some states have their own, and strictly speaking, the federal second amendment wasn't officially imposed on the states until 2010. (Yes, that does mean that states without their own constitutional restriction could have regulated guns as much as they wanted within their boarders.)
Texas does have one, and its an interesting case.
Sec. 23. RIGHT TO KEEP AND BEAR ARMS. Every citizen shall have the
right to keep and bear arms in the lawful defence [sic] of himself or the State; but
the Legislature shall have power, by law, to regulate the wearing of arms, with
a view to prevent crime. (Feb. 15, 1876.)
Which is interesting because it has an explicit out for regulating carrying of firearms that the federal constitution does not. Doesn't really matter now that the 2nd amendment is incorporated to the states, but the fact is that Texas would have expressly allowed certain regulations on firearms.
