Concealed Carry In Texas
Under the Texas Carry Law, a licensed or unlicensed person has the right to carry their handgun open or concealed. The weapon must be carried in an approved holster regardless of how you choose for it go on your body- there are no laws specifying where these holsters can/cannot located. When Texas passed its own law for unlicensed carry it came with its own restrictions and penalties.
