There are young people under the age of 21 that want to go target shooting or hunting. If some one is unstable and should not own a gun their age is irrelevant. I love theses people that say all semi automatics should be banned. Clearly they don’t understand the difference between an automatic and semi. This has nothing to do with age. This is about breaking the second amendment. Maybe they should make a law that you have to be 21 to own a knife or car. I love how at 18 you are considered mature enough to fight for our country but yet not mature enough to own a gun.
