I really appreciate all the input. I've changed my mind on what to get him for his first firearm. I was looking at the Ruger 10/22, but I want him to take his time and focus on shot placement and trigger pull. I've decided to get the Mossberg Plinkster bolt action .22. It's a single shot with a detachable magazine. You can also purchase additional magazines with higher capacity. We can always move up to a semi-auto in a couple of years. Thanks again for all the advice!
