End of last year I bought a 629 classic and a 329pd both new and both had to go back to s&w right away, the 629 had machine marks up the front of the frame, but other than that it was good
The 329 had a massively crooked forcing cone (.011 -.005), anodizing missing is spots, punch marks around all the shroud pins and a few other cosmetic issues.
I was very disappointed in these expensive guns being sent out looking like this, sent them back with a note on what I wanted the barrel cylinder gaps set at and they came back perfect... like how they should have been when they left there the first time. But anyway it all worked out.
Edit. It took 4 weeks for the 629 and 5 weeks for the 329 to get them back.
