Federal law says you have to be 21 to purchase from a dealer, but you may own a handgun at any age.
Minors may own firearms that are given to them by their parents, relatives, or legal guardians. However, they may not generally possess firearms unsupervised until they are 18 years of age. There are exceptions to this rule, such as when a minor possessing a hunting license and having passed a hunter's safety course is hunting, possession of firearm(s) on certain types of private property, and possession of firearm(s) in one's own home.
If you purchase from a private party you must be 18.
Knowingly selling a firearm to a person who cannot legally purchase or possess the firearm (such as a convicted felon, minor, or drug addict) is illegal, and punishable by up to 180 days in jail. Under state law, you must be 18 to buy a firearm of any type (handguns or long guns) from a private seller.
