Field stripping a recently acquired 3913TSW I noticed some strange looking wear/peening on the top of the frame where it contacts the slide. I can feel the marks on either side with my finger nail, and where it curves inward it gets deeper, maybe .005-.010". I looked at my 4003 and noticed something very vaguely similar on one side but nothing like this. It has not been fired by me yet but the slide seems to move normally.
It still has me a little concerned though, it doesn't seem normal.
The slide looks ok.
The area in question is right above the trigger shaped like a hockey stick.
Anyone ever seen this or make out what's going on with the receiver?
