On a person to person sale, you don't have to have any information. If you suspect the person buying it can't legally own a gun, you are obligated by law not to sell it. If you go into a gun shop to sell it, the will ask for your driver's license or other proof of identification.
Two forms of ID, one of which is a govt issued photo ID, showing that you are at least 21 years old, and a resident of Texas. (You may only purchase a handgun in your own state of residence) You will also need the money to pay for the handgun (of course), and the ability to pass a criminal and mental health background check.
You can not carry an unconcealed handgun in Texas with or without a license.
The answer is yes and no. You cannot go into a gun store in a state where you don't live and walk out with a handgun. You can, however, have a handgun shipped from a licensed dealer where you are to a licensed dealer in your state and pick it up there, unless there is a local state law prohibiting that. You have to find a gunshop that is willing to do that. Some will, some won't.
No, Texas does not require handgun registration.
Anyone 18 or older can purchase a firearm in Texas (from a private seller). Only licensed dealers can not sell a handgun or handgun ammo to someone under 21.
Rifles and shotguns, yes. Handguns, no, you must be 21 to legally purchase a handgun.
Legally, no. You must be 18 to purchase a rifle or shotgun, and 21 to purchase a handgun.
It depends on what you mean. Federal law says you cannot purchase a handgun from a licensed dealer unless you are 21 or older. You can, however, purchase a handgun from an individual if you are under 21 if the state you are in allows it. Some do, some don't.
Generally speaking, no. If you have a felony, you cannot legally own or purchase a gun.
You need to get a judge to expunge your records.
By federal law you may own or possess a handgun at age 18, but you cannot purchase handgun ammo or a handgun from a dealer until age 21.
It depends. If you are a U.S. citizen, length of residence in a particular state is irrelevant. However, you will have to have some government issued ID with your current Texas address and your photo on it in order to purchase a handgun from a dealer in Texas.
No, although handgun purchases do require a purchase permit.
