Remember, Hoppe's #9 is nothing more than perfumed Kerosene. It clearly states this on the label. I keep #9 on hand to use only for removing fouling from the barrel or to rid the firing pin area of primer residue and nothing else. Even in this application, I first try to use a good oil like CLP,Beretta Olio or the Benelli Oil. These oils will not only protect against rust, but they will also cleanse to a degree if clean burining ammo was run through the weapon you are cleaning. Since Beretta has a major role with Benelli,(Possible stock ownership and import rights per a Beretta Representative. Wonder why HK no longer imports Benelli and Benelli's new address is Accokeek,MD?)I beleive that the Oilio and Benelli Oil are one in the same. I believe that the lubricant you choose is extremely important and that oils with a flamable solvent base such as Rem oil should be used only for cleaning and not lubrication. Flamable solvents tend to eat away at the finish over a period of time and they are not good for rubber grips. It's worth spending the extra money even if you do clean frequently. In my cleaning kit I keep Beretta Olio, Rem Oil and Hoppe's #9. The Beretta is an all-purpose lubricant. The Rem Oil is used to clean the bore and firing pin area and the #9 is a last resort solution for tough fouling, primer buildup or the beginning stages of rust. If I were you, I would keep the #9 and get some CLP in the squeeze bottle for lubrication. Remember that aerosol sprays use some sort of propellant to get the lubricant out of the can and that agent may or may not be good for the gun. I avoid slide greases since I live in a region prone to dust and I can't stand the grit build-up that slide grease will cause if you store guns for a period of time. To me the advantages of Beretta Olio are: (a) it won't hurt the gun's finnish, (b) it does not attract lint and dust and (c) it acts as a cleaner also. The main disadvantage is it costs 7.00 per ounce. Pay me now or pay me later.
