Don't mess around with a new gun with that list of issues, use the warranty!
E-mail or call S&W Customer Service and describe the problem, (leaving out the part about the reloaded ammo!!). They will send you a return shipping label for two day FedEx as the gun is new and under warranty. I've had two warranty repairs done by S&W this year and the guns were out of my possession a total of two weeks both times.
