I found a S&W 5906 that was in excellent condition. I just got back from the range and was very disappointed. The gun wouldn't extract. I took it to my local gunsmith and he tried to order an extractor from S&W. They told him to send the gun back to them. I have never had a problem with any S&W. How is their repair service. Is this a common problem with the 5906? Is this going to be an expensive fix? The 5 rounds I shot grouped very well and I hope to have this gun for a long time. I love the weight and stainless steel of this gun. The recoil is very comfortable. Thanks for any help.
