Taj,
I made note of the extractor rod in my letter to Smith and Wesson. Ten years ago I attended a S&W armor course that was job related. Seems like we had a tool that had two prongs that fit into two of the cylinders and a handle. We wrapped the extractor rod in a rubber pad and used hand strength to loosen and tighten. Been ten years so I might be wrong. I will never use "locktite". Perhaps my service rep will take a moment to correct that also. If not, I will follow you suggestion. Seems like a good method. I have high hopes that the gun comes back right. I do not like seeing the rear sight hanging off to the right side by a few threads just to get a center mass hit. While researching the topic, I have seen all types of stories about expectable amounts of barrel cant. I can only hope that my gun returns and the problem is corrected. My past "official business" interaction with S&W with department weapons was always top notch. The Armor course was some of the best training I have ever had. Time will tell with my 629. I have high hopes.
Bill
