Purchased a 9mm shield at academy, didn't really look at the barrel at the time of purchase ... the next day I was cleaning the gun (did not shoot it) and noticed it was dirty.. I know they test fire it so I didn't think much of it, but when I inspected the barrel it looked pretty worn and sorta scratched ... like it it went though a few hundred rounds... my sig when purchased brand new had 0 marks On the barrel ,is this common for this gun / normal?

I called academy they said they don't sell used guns, I know the guy sold me a new on in the box so it wasn't from the display.









Not my image below but this wear I also noticed on my gun
