I have two Glocks that are less then a year old and both are babied, even though they could stand the abuse I baby all my guns. :embarassed: I have noticed that on both guns the rear sight is getting rounded along the edges. It's strange because I can't think of anything that is coming into contact with them. My holster doesn't touch the rear sights. Anyone else having similar experiences where the rear sights are showing some wear despite nothing coming into contact with them? These are the plastic stock sights.
