A way too long FP can keep the gun from closing.
If the pin is hanging way out there, it's tip can end up underneath the extended extractor/ejector while closing the bbls. That makes for a clunk as the pin hits the underside of the extractor.
That can bend the tip on the already too long FP as well as put some dent damage on the underside of the extractor blade.
The extractors should have a shallow beveled cut in them to push a proper length FP (shorter protrusion) back into the action as the bbl is closed.
Cut the pin back so it allows somewhere betw .035 and .045 protrusion and with a nicely rounded and polished point.
Most everyone will have a perfect protrusion length for a FP, but I have found the above to be completely reliable with proper hammer fall and HS. Plus no un-necessary extra length to it.
...No peened yoke screw in the CSMCo Fox that I ever ran into. Not to say that they never did it though..
