Hi WLB,
I know this is an old thread, but I am in the same situation you were, only many years later, and would like to know how you resolved your quandary! Did you ever get your SS controls for the 4566? Mine is a TSW and I just cannot get used to seeing the black controls on the SS body. Any suggestions for interchangeability for these parts (slide-stop, trigger & ambi safety/decocker)would be very much appreciated!!!
Thanks
Mike
