Just clean, including the spring, with Hoppe's inside and out. Let dry. You can wipe with a silicone cloth if you want.
Re clip vs. mag. I prefer mag. I have a buddy who was a Marine M-60 gunner in Vietnam and got to use his 1911 extensively as well. He calls mags clips. I don't correct him.
If you want to shoot...shoot...don't talk! Tuco
