ToddG said:This is a picture of the other side of the breechface from my gun at 16k rounds. It also shows wear. Hasn't caused any problem in terms of reliability or accuracy in the 5,000 rounds I've shot since taking the picture.
It's worth noting that my barrel isn't standard and it doesn't have the Melonite finish, so that may have an effect on how the slide is wearing at these particular contact point.
