Thats the same idea illegals have and why people get thrown in jail. That's why I wont sell a gun to anyone who doesnt have a Texas ID. Legal or not, I prefer to cover my ass.A resident does not need a Texas ID to buy guns from individuals, nor dealers.
Buying from a dealer has been outlined above.
Buying from an individual has been incorrectly outlined above, to wit:
There is no "time limit" or "ID card requirement" for residency when dealing with individuals (face to face sales). Under Texas law, the instant someone enters Texas with intent to reside, they are considered residents.
