Years ago there were a lot of reports of a lot of machining crud left behind in the striker channel during manufacture.
Due to those reports when I got my PM45 I took it apart before I shot it and found the striker pristine although heavily oiled.
Seeing as Kahr has no control over how long the guns will be in inventory at distributors or dealers, they are wise to oil them up well.
Most found that once that initial crud was cleaned out, it wasn't an issue again. Some flush the striker channel with brake cleaner through the little clean out hole during cleaning, I seldom do that myself. In this case it certainly wouldn't do much good, too much crud and too big to flush out.
I'll be curious to see if you get anymore after yours is clean and put back together dry. I doubt it.
