I have a Ruger P94 that has bee a dream to shoot. However , the accuracy has started to slip. I have noticed on the forward slide rails the tops of the two sides are "stipled" and the right side rail is starting to round off. This is caused by the rear outside chamber area of the barrel. When the slide comes back during its cycle , the barrel tilts downward onto the the tops of the rails, causing the dents and the rounding. How much more "damage" will this do? With the slide forward it is not as tight as it used to be.
