Bumping this thread... Up in the 2K range since my last post, having only (2) failure to fire issues. I'm blaming ammo since I have not replicated the issue since.
I have about 2300 rds thru my Sport with NO failures of any type. This is better than any firearm I've ever owned in 52 years. Part of this is due to the fact that I only use decent brass cases ammo but the real credit goes to S&W!!
