I don't need to replace my ejector yet, but..looking in the receiver over the barrel, I see a small screw?. Is that a pin or an allen screw? Has anyone removed and replaced the ejector? Does it take a special tool to remove that pin/screw?
I have never seen a video on that repair..

Found the answer on another thread. "Stay away from trying to replace it. Smith and Wesson factory return only repair."

Very doable without returning to S&W. This is one of my favorite, all-time videos regardless of subject matter. Why? It highlights the absolute insanity of human thought at times. Sometimes when I need some humor in my life, I watch this video.

Thanks.I'll take good care of my ejector..

I recently replaced an ejector with no custom (expensive) tools except the barrel nut wrench. Took about half an hour. Midwest Gun Works has replacement ejectors.
The barrel extension holds the ejector in place. The extension is retained with a roll pin which is easily removed with the proper roll pin punch. I then tapped the extension off and back on with a brass punch. Just don’t get in a hurry.
