Concealed carry or carrying a concealed weapon (CCW), is the practice of carrying a weapon (such as a handgun) in public in a concealed manner, either on one’s person or in close proximity

While there is no federal law specifically addressing the issuance of concealed-carry permits, all 50 states have passed laws allowing citizens to carry certain concealed firearms in public, either without a permit or after obtaining a permit from local government and/or law enforcement. – Wikipedia.org

The Texas Department of Public Safety monitors and regulates LTC use for the State of Texas.
“DPS licenses individuals to carry concealed handguns within Texas, evaluates the eligibility of applicants through criminal history background checks and monitors those currently licensed to ensure their continued eligibility.”
