QC of Smith & Wessons is hit and miss on the recent models.I think they just churn them out and then worry about sorting out the issues later.Ive read of numerous examples of issues with the newer smiths.That is the reason that the 3 Smiths I own(models 17/27/29)are all older manufacture(60s and 70s).Way better quality and finish and theres also not that ridiculous hole in the frame for the lock.
