Jack First Gun shop is still in business and they have firing pins for the S&W 422/622/2206 (28.00 ea.) I ordered 2 and I even ordered an extra FP for my S&W Model 61. (22.00) plus shipping. They make them in their machine shop.

You can find grips on ebad. The factory black rubber sell for pretty cheap but I have seen the factory walnut grips go for over $100.00. I bid on a pair of wood grips that ended during the Super Bowl and picked them up for $35.00. They were factory grips and came sealed in a factory bag. I guess I did alright on them.
