Texas does not require a separate state permit to purchase a handgun or long gun, though buyers must meet federal age minimums (21 for handguns and 18 for long guns from an FFL) and be free of any prohibiting factors under federal or state law. Out-of-state handgun purchases must be transferred through an FFL in your state of residence.
Texas allows permitless carry for qualifying adults aged 21 and older, but a License to Carry still offers reciprocity benefits when traveling. Transport firearms unloaded and cased when practical, and store them in a locked safe or lockbox separate from ammunition when not in use.
