[Scout]

I took the boys to shoot sporting clays for the first time a couple of weeks ago. It was my first time, too. We all had a grand time and I'm happy to say that I think we've found our common sport. My 15 year old is 5'8" and 120 pounds. We both shot an old Model 12 in 20 gauge, which worked great. My 12 year old shot a Mode 500 youth model in 20 gauge and did pretty well. My question is: What gun would you all recommend for my older boy? He enjoyed the Model 12, but I'm wondering if a 12 gauge might serve him better in the long run. He seems entranced by my friend's Beretta semi. Also, Is it easy to put a full size butt stock on my little one's model 500 as he grows? Thanks for your help.
