I've been doing quite a bit of shooting with my 14 year old daughter, and she's very good. She shoots my 26 and a Springfield xd9 that's unofficially hers. The other day she shot my brother in laws 23 and decided after the first round that she wants a 21. Now the 26 and the 23 isn't enough fire power for her. I was shocked and proud at the same time. Looks like I've got a good excuse to purchase another Glock now.
