I bought my 12 year old a Walther P22 last year - and its a blast to shoot. I decided I want to be a kid too - Whats a great .22 pistol that I could possibly put a scope on? Wanted to keep it around $500-600. The scope would be just for fun target shooting - no real hunting. I hear great things about Brownings and Rugers - but which models? Would appreciate any help!!
