Probably has Teflon or Moly (molybdenum sulfide) in it.
Government Models like to have a little lubrication of a clingy nature on their slide rails, and where the slide rides over the disconnector and hammer. Also where slide and barrel connect (rear locking area, front bushing area).
Not much. Better to use too little and replace it often than to use too much.
You might also use a little on the hammer pin and where the mainspring strut pivots inside the hammer. Maybe a tiny bit among the sear/disconnector internal parts, too.
