This is the second 4013TSW I've seen that has a slide stop that seems to be chafing or at least marring the slide. I checked my 4003TSW thinking it may be common but the slide doesn't even come close to the stop.
The 4013 in the picture below is supposed to be like new, and otherwise it does look as new, but seeing this on two near pristine 4013TSW pistols recently is strange. The 3913TSW uses a slide stop with the upper part cut away but the 4013 and 4003TSW does not, is this something specific to the 4013TSW?
Anyone know what's going on here?
