Gunwizard,
I just found this inquiry RE: J Korzinek. I'm sorry that I cannot shed any light on the Rugers that He converted. Many years ago, I visited his shop in the Canton, PA area while on a ground hog hunting trip. That general area was a mecca for ground hog hunters. He was very cordial, considering that I just dropped in to visit his shop out of curiosity. I never heard any negative comments about his work.
