I was looking at my P88 while trying to answer a previous topic. I was looking pretty close at my P88 and noticed something disturbing.
When looking at the muzzle of the barrel the barrel rest against the bottom of the slide.
The hole in the end of the slide is not round. As I look at it from the end I notice a crescent shaped space between the barrel and the slide. This I imagine allows the barrel to tip up as the the slide is racked.
Now to my worry...
The crescent shaped empty space is not uniform in shape. It seems to be thicker on on side than the other.
Maybe this needs a picture
the picture is exaggerated to help illustrate the point.
