There is no permit, background check or firearms registration required when buying a handgun from a private individual.
As of Sept. 1, 2021, permitless concealed carry and open carry is legal for anyone at least 21 years old who may lawfully possess a handgun. The new law applies to both open carry in a holster and concealed carry, where no part of the firearm is visible. Texas law is quite specific in that openly carried handguns must be kept in a holster.
Texas LTCs are issued to both residents and non-residents who are at least 21 years of age (18 if a member or veteran of the U.S. military). They require a four- to six-hour training course as well as passing both a written exam and a shooting proficiency demonstration. Some areas are off-limits, including racetracks and secure areas of airports.
In terms of reciprocity, since Texas allows permitless carry, any person 21 years of age* and older who can legally possess a firearm may carry a concealed firearm on his or her person without a license or permit.
*United States District Judge Mark T. Pittman ruled that 18 to 20 year olds must be allowed to carry a handgun outside the home in Texas. He allowed this to be done by letting them get a Texas license to carry. The Texas Department of Public Safety (DPS) will now issue a Texas LTC to anyone that is at least 18 years old. On Jan. 10, 2023, the Office of General Counsel sent a memo to DPS offices directing them to no longer enforce the state law that bars adults under 21 from carrying handguns in public.
