The 870 is a great gun. It is the platform that I, and countless other people have learned on. I got mine when I was 18 so I never needed the scaled down stock, but as far as I know, the only thing different about the youth model is the stock dimensions. This allows you to swap it out for a full size stock whenever the short one is out grown. If you do a search, there is seemingly an endless amount of discussion about all things 870.
