cknight98,
I am not a big fan of the S&W autos, but have to ask if you disassembled and gave the gun a good clean and lube after your first range session? SOP for me is to disassemble and clean/inspect/lube before firing the first time and of course afterward. I have seen new guns that were full of foreign matter and improperly lubed right from the factory. Add in a few rough mating surfaces and you have a nonfunctional weapon. Before you bury the thing I'd perform this task, borrow another magazine and try another range session. If this does not solve your problem it's time to look elsewhere for your CCW!
Stay Safe,
Savage
