I finally got it back together. NOW I am taking it apart to refinish it. How do I get the magazine release assembly out? It looks like a large cross-headed screw is holding the trigger bar spring, the mag release spring, and its assorted parts, in. The screw doesn't want to budge. Also there is a spring associated with the slide release/barrel lug pin, how does it come out?
(edit) Got it, liquid wrench on the screw and drove out a pin on the slide stop retaining pin.
