Took my new p320 9c to the range this past weekend for the first time. My wife and I combined put about 350 rounds of no less than 8 different varieties of ammo through it. From 110-150 grains, brass, steel, and aluminum, ball and hollow point. One fte with some traditional crappy Midland reload (this happens with just about every pistol). Smooth! If we could've afforded to we were ready for 350 more. Went home and cleaned it, following the factory manual first time around. Took out the fcu and noticed a bit of black wet soot on it, so wiped it off. Then saw a smudge back by wear the trigger bar pivots in the fcu body. Wiped that off. Found some more, wiped it off. After that I noted that it was whitish and greasy. Drat! Maybe that was supposed to be there?!? Anyone know if this is so - should I reapply some or was this just a factory preservative type thing?
