Well I just got my new S/A G.I. (parkerized) on a trade.  I took a Hit, but this is what I wanted and I know that I am much happier with another 1911.  No pics until after the 10 days (good old Cali).  After a couple thousand rounds I'll send it off to Yost-Bonitz or Novak.  I am wondering if I should start buying parts here and there that I want to replace or just wait until I send it off to a Smith.  What say you?  As far as the G.I.'s go what stock parts are good enough to keep?  Thanks.
