I use about 5-7 drops of oil on my guns (1911s). Frankly they don't need to be run "wet" or all greased up like a buttered turkey and it's a bit of a myth that they need it.
If I was going some place humid or very dusty I might use a bit of grease on the rails. But other than that I'm not on a mission in the jungles of Borneo, up the Amazon, or fighting aliens in the frozen heck of a Siberian forest. Pretty much I'm not much more than a day away from a good cleaning.
