Picked up a M22 Smith this A.M. Took it apart when I got home to do a trigger job (primarily polish parts, dress hammer spring & see how it looked). I haven't bought a new S&W in going on 15 yrs. I was stunned to see all internals are MIM parts. Wish I'd kept all those old S&W parts. It did clean up OK but, God I love it when nothing changes.
