I came here to say the exact same thing. I use "Super Lube" grease on all of my pistols. It is smooth as butter, there is almost no wear on the rails or other components, and the grease sticks on there through hundreds of rounds (whereas when I used oil the gun was dry after a few mags.) I got the "sportsmans kit" from super lube on amazon. Its a small kit you can put in your range bag that includes grease, oil, and applicators.
