Looking for some advice here! First I have been a police officer for 20 years, so I obviously know nothing about guns. I am looking to get my 12 year old nephew into shooting. I have his parents blessing and want to buy a handgun that he can use, under HEAVY supervision, at the range with me. I am pretty sure that a .22 would be the way to go, but after that I am lost, Semi v. Revolver; any specific models designed for the novice small framed shooter; OR should I scrap the whole thing and grab a starter rifle... which means I am even more lost... if that could be possible. Thanks in advance and I will take any advice I can get.
