It’s irresponsible. From what I’ve read even some the “gun people” are saying you should allow a nine year old to use a gun like that, and Uzi. If you want to teach your kids to how to, and the safe, responsible use of guns, you might want start with something a little more sensible. An Uzi is too much gun for a nine year old girl. And why? Why teach a nine year old to use a submachine gun? No matter want you want your kids to learn a parent’s job is to find an age appropriate way to do it.
