Springfield Armory has excellent customer service. Call them, give them a few details, and they will send you a pre-paid FedEx shipping label to return it for service.

Also, as others have suggested, please note the exact nature of the "jam". Is the spent cartridge still in the chamber (failure to extract), or sticking out of the ejection port sideways (stovepipe)? Does it extract the spent cartridge, but fail to pick-up a new round from the magazine? Does the new round hang-up on the feed ramp and not move fully into the chamber? Does it chamber a new round, but also try to load a second new round behind it as the slide comes forward (double feed)?
