Texas

Age requirements vary: 21 for those who completed military service or civil service equivalent, 27 otherwise, and 45 for non-citizens. Must pass a background check (criminal, health, and mental history), establish a genuine reason for possessing a firearm (such as self-defense, hunting, or sport), and pass a weapons-training course.[244] Around 40% of applications for firearms permits were rejected.
Those holding firearms licenses must renew them and pass a shooting course every three years. Security guards must pass these tests to renew their license to carry firearms belonging to their employers. Applicants must demonstrate that they have a safe at their residence in which to keep the firearm. Permits are given only for personal use, and holders for self-defense purposes may own only one handgun and purchase an annual supply of 50 cartridges (although more may be purchased to replace rounds used at a firing range)
