From your posts it seems that you are implying that a lot of these gentlemen are making this stuff up or just flaming S&W? I personally haven't had a problem with any of my guns but I have witnessed a telephone call go very very badly on a M&P 15-22 when my relative just asked on the status of the gun. When he got his firearm back all it had with it was a note saying "updated to latest specs".(granted the gun worked fine ever since, really cant ask for more than that BUT he wanted to know exactly what was done to his gun as any customer would and they would not tell him anything/said they could not tell him anything.) IMO that is bad customer service, also had a LGS owner here call about them and asked about the problems with the guns and he got the shaft as well. He had 4 guns sitting in his shop at once and was pretty upset that people blamed HIM for selling junk, smith wouldnt give him any answers and said they hadnt heard of any problems with the guns.
There are STILL people sending these guns in a year later and getting that same response, "we arent aware of any problems" Things like that are what have me hesitant of buying a new model S&W, of course im just 25 years old and do not know my butt from a hole in the ground but bad business practice goes a long way.
What if I buy my 629 and have a serious problem with it, only to have to send it back and they tell me that they have no idea what is wrong with it or what was done to it, how would that help me in future endeavors? Usually if a car messes up and I go to my mechanic he tells me what was wrong, from things like that I have learned to work on cars on my own now if i experience a problem such as the one I had prior.
I guess what im trying to say is just because you have had great experience with a product does not mean that everyone else will have those same results. Maybe some of these people are buying based on the long time track record of S&W (i know i did, my grandfather told me to never trust my life to something that wouldnt work, buy S&W) Here recently that hasnt been the case, or so it would seem from these forums, of course it could just be that more people that have problems would come to a forum looking for answers! I feel bad for the OP in this case, a PC gun should not have had any issues at all.
