Lloyd you are so polite but call me David. As far as putting oil on your barrels after shooting and cleaning, Dr. Gaddy recommended using used motor oil after blueing and or etching barrels. I use either a silicone-based cloth or a very light coat of Rem Oil after cleaning. I am lucky in that my hands do not leave any fingerprint rust marks like my wife's do. Any oil will work so use it sparingly. A couple times a year I would also take the locks off (make sure the gun is cocked or you won't get them back on) and use a Que tip dipped in Hoppe's or a cleaner of your choice to clean any residue and then use a Que tip with a little oil to protect the bare metal there or sooner if out in the rain.
