I always feel for the folks that get one of the less than outstanding examples of the Gunmaker's Art from any manufacturer.
I too have read all eight of the OP's posts since he joined the Forum in March. Every one has been about his bad revolver.
It does appear that the intent may be to stir controversy.
One of the things that caught my eye is that an alleged certified instructor who is also a shooter of more then thirty years first visits the S&W forum to complain? Not a single other contribution to the Forum in 30 years of shooting.
Secondly, the alleged reason the 317 was purchased was because he was an instructor? I am also a Certified Instructor of many decades and I do have a 317 in the inventory but it is there as a curiosity, since it is one of the lightest S&Ws ever produced. It probably has not had 500 rounds through it in 16 years I have owned it since it's manufacture. I find my Model 17s to be far better teaching revolvers for novice shooters. It makes it easy to transition to model 14s as skills progress
Third, the first thread complains about accuracy issues with the 317 but group size is not mentioned a single time in any of the eight posts. The actual complaint expressed is that Point of Impact does not match Point of Aim by more then 4". I want to believe that a Certified instructor who is a shooter with thirty years of experience would know the difference between accuracy and a Point of Impact issue.
The last issue is that I question a Certified Instructor that would choose to add an allegedly $700 pocket 22 revolver to the training inventory. Why purchase at a price that is inflated by the current uncertainty among much of the public.
As posted above you state "that was the last S&W purchase I will EVER make." I would have to ask, is this the first S&W you have ever purchased?
It just sounds like either we are not hearing the whole story or some of the story is being expounded upon for a more dramatic effect.
Regardless of the above, I am certain that S&W will make this right. You just have to wait for them to have a replacement revolver to send to you. I know patience is hard when you have a new toy in the pipeline.
