Here are two of the inside of the slide. The lugs have some wear, but it also looks like some metal - just a little bit - is being 'pushed.' Like a bit of 'burring' (not knowing the correct term) is forming. It is hard to see in the pictures, though a bit can be seen in the second.
Here is the top of the barrel. Not bad looking. Once again, hard to see, but the front edge of the second lug has a bit of a 'bump,' as if metal has rolled up. Just a tiny bit, and it can hardly be seen, but it can be felt. Is that normal?
Two shots (as clear as I could get them) of the underside of the barrel. This area looks good. No apparent issues.
Finally, two of the inside of the frame. The first is natural light, the second has a flashlight shined across the top, to bring out the marks on the top of the slide rails, and the inside angled portion where the barrel rides. Unfortunately I don't know if this is galling, or just left over mill marks.
