My reading comprehension skills are not good. I know what the book says.
i have oiled the piston on my Beretta SAs for 30 years. NEVER CAUSED A PROBLEM!
what I found was it was way easier to clean the piston, often time just wiping it off.
With no oil, it bakes on and requires a lot of elbow grease to remove.
You do it your way and I’ll continue doing it my way
