I got a S&W 22A around a dozen years ago to shoot it with my sons. We put over 100,000 rounds through it together. The gun had several firing pins broken, the sight rib, the frame and also the hammer spring.
Still shoots well but is now more in the back of the safe. The main reason why I bought the 22A, was that my sons were a bit rough on my nice rimfire pistols and refinishing one of them would have cost more than this little plinker.
