So about 3 weeks ago I went out shooting my sigma, after coming home and cleaning it I noticed the guide rod (plastic) was wearing. I have had the pistol for over 2 years and shot many many rounds through it. But the guide rod made the gun jam up when i cleared it after the cleaning before puting in the safe. ( I will clear a empty gun many times, I am a safty freak!) Seems the guide rod was worn enough to slip off its ledge, so I called S&W up they said send it in, I did that about 2 1/2 weeks ago and today I got it back! They replaced the guide rod and the extractor! This was my first time sending a gun in to be fixed and I am very happy with them! Also now I have my lovely sigma back. Been carrying a 1911 past few weeks which I love, but I have a fantastic holster for the sigma and now I get to enjoy it!
