You shouldn't have any excess oil around the extractor, the oil will only accumulate fouling more quickly which will inhibit the free movement of the extractor and can cause failures to feed and failures to eject.
The FTF's could be an ammo issue or a magazine issue. If I'm not mistaken, being in Italy your G19 would be chambered in 9x21. Are there any numbers marked on the followers of your magazines? Are they 10-round magazines or 15-round magazines?
I'd try holding the gun more firmly in case it's caused by limp-wristing, if that doesn't fix the problem try some different brands of ammo if you can.
