I already have a new rear sight, slide stop, a solid trigger, and extended mag release from John Harrison. I think I'm going to replace the thumb safety with a wider version, I'm thinking one from Ed-Brown. And last but not least I have a one piece mag well from S&A, however I am really liking the Stan Chen magwell. Any opinions on what I have picked or anything else that should get replaced while I'm at it? I think I'm going to get the gun re-coated in Black-T as well, maybe I'll spring for ion-bond. The picture is from when the gun was new. It's pretty beat now and since i would have to get all of the new parts coated to match I figured I would upgrade.
