The tenifer coating on the slide is extremely hard, and that coating is inside the slide rail grooves. There's bound to be some wear present. Since the gun is basically new and barely fired, it's normal to start to see some visible wear developing. Give it more time and more rounds fired through it, and it'll smooth out normally. The components involved are the same between Gen3 and Gen4, so it's not a generational issue. I've seen this occur on all new Glocks I've ever looked at or inspected.
