Looking to buy a firing pin for s&w k22 .22cal revolver
Can't find one on line

Suggestions----where I'd look first: S&W, Brownells.

Now that said, the K-22 has been around since what----1932? That being the case, if you tell us what vintage K-22---or give us the serial number, we can do a better job-----for instance, neither S&W nor Brownells is likely to have one for the 1930's model.
