Maybe it's not a big deal.

1. Yes it sucks, you purchased an expensive NIB firearm and it has factory flaws pertaining to the functional operation.

2. It's a S&W. They will fix it for free. They will even send you a free S&H label. It will be returned to you free of charge.

3. You could be a leg up on other NIB gun owners. Your personal gun is going to get personal attention. Be inspected, maybe refined with upgrades (it's happened) and repaired to better working conditions than when you initially received the gun from the factory line. It may have missed QC before being wrapped in paper and boxed, but now it will be eyeballed by a repair technician.

BTW, I had a $1500.00 PC952 shipped back to the factory two times for repair. It happens, you are not alone.

Good luck!
