2244, the pack date was 3-26-2013 according to the label on the box. I purchased it on 3-28-2013 according to my receipt.
2K7, you know I honestly should have done more research into this model and the issues to look for before I put down my cash. At the point I had purchased it, finding ANY S&W pistols was like finding a needle in a haystack, especially the J-frames in my area. So I was just glad to find a new one at the store. And as being my first J-frame with the in frame rear sight, had no idea (till now...) that there might be an issue. I work for a fairly large aerospace manufacturer... should have known machining issues do arise from time to time!
As for letting it slide, I think the best thing to do is send back a pistol anytime there is a manufacturing issue. If S&W finds a great way to build pistols at the SAME quality level, then by all means because that is a very good lean manufacturing model. But when it puts out subpar goods, they will definitely feel it in the pocketbook when profits go to paying for repairs instead.
I'll update this as I find out what all they are wanting to do with this one. Thanks guys!
