In Texas, open carry of pistols & revolvers will be allowed come January.
Some areas will limit it, but generally, open carry will be OK.
But not swords, knives and/or maces. They are arms just like pistols and revolvers.
I would actually like to carry my flanged mace openly. It will break bones (mainly), not kill, unless I deliver a head shot.
I'm far more likely to kill with a pistol if accosted (center mass is natural reaction) which is not what I desire while defending myself.
