Hello folks, I need some help here. When I remove the slide from the frame, and the two steel inserts are visible at the front of the frame I see a notch towards the top of the left front rail. I first noticed this notch after I shot the 200 break-in rounds. I did not notice the notch when I field stripped the pistol to clean it when I first got the gun. Anyone else see this type of a notch in their PM9? I asked Kahr about it and the answer I received is that "they are all like that". Anyone with a PM9 see this notch in their gun? All feedback is appreciated. I tried to post a picture 6 times and I keep getting a Glock Forum error. It is extremely frustrating as a picture is worth a 1000 words.
