Looking for a 22 handgun for my son. He is 6 and just shoots a 10/22 with the help of me. He has small hands since he's 6. I would also like to plink with it and I don't own a 22 handgun. Any recommendations? No price preference, 22lr, plinking, small/thin grip, reliable, and something to train him on of course is what I'm looking for.
