I have one and it binds with Winchester Ammo but not CCI or Remington Gold HP's. It will also start to get tight after about 150 rounds so I make sure I really clean the chambers well. This has been posted several times up here and I think it because S&W made the chambers to really tight tolorances because it was a target gun.

The K22 and Model 17 are both great shooting guns though and are some of my favorites.
