By "Zombie Mode", I am more frequently getting "double-taps" on the single trigger pull.
Any Explanations to offer?
Also it hates steel-cased ammo. Does not eject steel casings, jamming after every shot.
Since I also average a jam about every 60 shots with brass, is this a spring issue?

Yes, I already thought you needed a little more poundage on the recoil. I think your perceived double tap is the hammer following the slide as that is a very dangerous condition that can result in a full auto unloading of a mag, YIKES!!!!!!!!!! It could be a worn part in the action, weak sear spring or possibly an over-adjusted over travel set screw.
Or too light a trigger pull. My Ruger SR 1911 and my Pointman Major C from Norwich are prone to doubletaps if I am not paying attention. The Pointman is tight as a drum and the Ruger is a loose goose but the trigger pull is down in the 3lb range on both. I am sure that is not YOUR problem but I am not very experienced and need fto develop trigger control.
I would LOVE to have at least one 1911 with that full auto problem. 😈. For those special situations.
As far as the steel cases, don't use them.

My new Guardian started doing that at about 600 rounds fired, when I double tapped. Full auto. Trigger pull was 3.5 lbs. I replaced the original sear spring (highly polished) with a standard Springfield Armory sear spring. Trigger pull went to 4.25 lbs. I could not feel the difference but could consistently measure it. Extensive testing and IDPA matches followed, now over 3000 rounds fired, no out of control discharges.
