.22 for squirrels

Well my son is finally of age and I'm getting him into the ol squirrel woods this fall! Looking at my .22's and they are great and all for my taste but so utilitarian (savage mk ii and 10/22 stainless with plastic stock). Longing for that gold trigger .22 my grandfather let me take. What would you all recommend for a first hunting rifle? How about a .22 .410 combo, I like that savage but hate the plastic look. I have a s&w .22a-1 to trade sell
