I use only a light coat of oil on my M&P. I clean it with oil, lube it with oil, then I wipe the oil off except a very light coat on the frame rails. It doesn't collect dirt or lint and I've fired upwards of 7000 rounds with no noticeable wear anywhere. Getting fancy with the lubes and greases may make you feel better but its totally unnecessary. Most people over lube their weapons rather than under lube. When your grease and oil turn into something that resembles the black sludge you find under and old Chevy's intake manifold I would think that isn't doing your weapon a whole lot or good. If you are in a dusty or sandy environment the grit that it also trapped by the lube will make a nice lapping compound. I'll keep using a very light lube.
Several guys have mentioned how the grease "traps" the carbon and makes it easier to wipe off. Where do you think it goes if it isn't trapped in the grease? Most it migrates out into the air rather than collecting in the grease and fouling up your weapon.
