I have previously posted about the extractor on my S&W 4013 breaking, and I am trying to make the repair myself. I went to the store and purchased an appropriate sized drift...and broke the bloody thing. Wrote S&W to find out if the pin was tapered or notched and it is not. I'm going to soak the pin with PB Blaster today and set to work on it tomorrow morning. Does any one have direct experience in driving one of these pins out? I could use some advice.
