I gots my PPSH today.
Loving it so far. I was wondering if anyone had any experience with the receiver pin? After field stripping it, putting the pin back in is difficult to align properly. It's the pin that holds the barrel and bottom receiver together. I matched the pin through each individual hole that it would have to go through, and they all fit fine. The problem is when all four holes are aligned together. Maybe the factory finish was a bit rough?
