Sometime in the mid- to late '70s I acquired this Smith & Wesson CO2 pellet gun. From that day forward, no varmint was safe in the neighborhood. Killed a boatload of rats with it. A good friend had a grove of avocado trees that attracted rats in droves. We used this air pistol and a .22 semi-auto pistol (I still have) loaded with CCI shot shells (it wouldn't cycle them so you would have to wrack the slide after every shot). Whack and stack rat parties...this is where the obsession began.
