2 of my 1911's are NP3 plated, which Robar said to run completely dry. Since I just can't bring myself to do that, they get a very thin coating of lithium grease, along with a dab of Mobile 1 20W 30 motor oil and they both run perfectly. My non-plated 1911 and my SA-35 pretty much get the same treatment, although during the summer months I use synthetic 90wt gear oil by the tiny dab along with the lithium grease (Lubriplate works just as well, I just happen to have a baby food jar of the stuff that's lasted for years and still has years to go). On stainless guns and my AR I use Brownell's black synthetic called Action Lube Plus and have never had any problems with galling. I've had the same 2oz container for many years and it will probably last the rest of my life! I'm a big fan of Break Free as well and use it in the actions of any of my guns although, several custom barrel makers said not to use in the bore, so I stick with synthetic there.
