I'm not really sure if I could have replaced the extractor myself or not? It appears it is pressed into the bolt somehow with a spring behind it. My guess is yes. It somehow got knocked out during a FTF? This is the first gun I have owned that the manual didn't have a parts breakdown? Oddly enough my gun worked fairly well with it missing.

When my extractor went missing I called Smith & Wesson and they wanted the gun returned. Seems like it would have been easier and cheaper to just replace the bolt. Maybe they adjusted the ejector also?

The paperwork I got back from them after the repair only said the gun was updated to latest specs? Very vague.
