I bought a S&W model 22A a couple years ago, and it'll shoot better than I can hold it. It came with 2 barrels, and 5 1/2 inch with iron sights and a 7" which I put a 4X scope on. I have killed numerous squirrels with it.

I can consistently hit a squirrel in the head with it at reasonable range, and I'm no genious with a pistol.

I have less than $350 in the gun, 2 barrels and scope. They're selling for around $200 here new with one barrel.
