I have a PDP F series. The roll pin in front of the take down lever keeps walking out a bit when I shoot it. I've used a punch and set it back flush 3 times.
I've got a friend with a PDP F series and hers is doing it too. Any one else having this happen? Any ideas? Any fixes?
My 4.5 full size did the same, contacted Walther and they asked for me to send it in. It turned out that pin was out of spec and they replaced it and sent it back. After 80rnds it seems to have moved a hair but nowhere near what it did at 50rnds.
