You can post pictures if you like, and we can say with more accuracy...
But I think you have unreal expectations of a handgun. The gun uses the Browning type of barrel lockup. The barrel rubs against the slide everytime the slide goes back. It is 100% normal to have wear on the barrel hood where it rubs the ejection port area of the slide. And, you will usually see wear on the finish of the barrel on the top and bottom of the barrel - where it rubs the front of the slide (where the hole in the slide is for the barrel to poke out). Every gun does this... The tighter the gun, usually the more wear.
Sometimes the finish on the slide and barrel play a part to make this worse or better - but it is 100% normal. It's going to happen.
You probably don't want to hear it - but the only way to not have wear on the gun is to not shoot it.
More than likely, Springfield will tell you this is normal wear and is just cosmetic, and they will not due anything. There is such a thing as abnormal wear due to poorly fitted parts, but such things usually look much worse and can start damaging metal
