M57 slide "chatter"

[kawasakiguy]

Has anyone ever seen hammer chatter on the bottom of a yugo m57 slide? Literally looks like slight punch marks running halfway up the firing pin area of the underside of the slide. These marks are coming from the hammer, the hammer is starting to "mushroom". I have added two links for pictures.

The quality and hardness of the two mating surfaces can cause deformation and gaulling.
