Watching " Smiling Larry" of Midway, he wets his fingers with oil and rubs the internals and springs with those fingers.
I think that's a good program.
A little of good lube goes a long ways
If it slides>>>Grease it If it turns>>>Oil it.
Except for break-action shotguns where it is the opposite.
There has never been anything wrong with lubing S&W guns, revolvers or semiautomatics, exactly the way they say to do it in their owner's manuals. If you don't have a manual for your gun, get it from S&W and read it.
BTW, it's oil...
I grease the internals more than use oil. Oil drips out.
Yoke, the pins, and on the sides of the rebound slide. Grease. I prefer boron nitride grease.
Light coat of oil everywhere else.
Except for break-action shotguns where it is the opposite.
Vaseline was the only recommended lube on early Luger's + many other firearms for many years - never seen it hardened on anything -I use heavy oil -- any 30-weight motor oil works well.
Light oil disappears way too quickly (it oxidizes too quickly).
Grease can cause problems because it hardens or turns gummy over time. Forget grease. (Although your mom's/wife's Vaseline does not seem to turn gummy or hard over time, who knows why).

Yep. I grease the trunnions on my under and over shotguns. I only use white lithium grease on my guns where grease is needed.
