LUBE very lightly, not dripping. For me, all of these might add up to 4 full drops, but I wipe down any excess that seeps out. :
Trigger pin and spring
Trigger bar: against the slide & a tiny bit in the groove on the bottom of the two legs
Mag release
Bbl Lugs
Slide bbl lugs
Bbl lugs
Recoil spring friction areas
Slide rails
Safety Pin
Slide release at frame contact points
Hammer pin & on friction areas
Hammer Spring rod
Sear friction surfaces
My Opinion:
DON'T oil/ LUBE:
Mags
Firing pin or F.P. channel
Extractor channel, but do clean it with gun solvent periodically (lubes a wee bit)
