1911 Trigger bar and over travel adjustment

I just received my 1911 back from Sig following AEP work. I've had disassembled and re-assembled it several times before this without any issue.

It came back drowned in a gallon of rust preventative requiring disassembled and cleaning (not exaggerating, it was literally dripping oil when removed from the plastic bag). Upon reassembly I could not put the slide in place. Forgive any tone, I just wasted an afternoon removing the irresponsible amounts of oil from places it doesn't belong and dont have a functioning gun.

The trigger bar lever for the firing pin block riders too high and even applying several pounds of downward force cant depress it enough to allow the slide to ride over it, it extends above the frame over 1/16" with heavy downforce applied.

I asked they adjust over-travel to correct the ridiculous amount of over travel and reset. Is it correct that this would in effect bring the trigger blow back and be what is preventing the lever from depressing?

Short of griding down the trigger lever, is there anything to be done without sacrificing the trigger work (taking the overtravel out to excess amounts)?

As it stands gun is not functional as I am not going to put 50lbs of force on teh lever, it should go together reasonable and not requir 3 hands. As it did before Sig did what ever they did to it.

Appreciate any suggestions or insight.

Thanks!

Just field, using compressed air to blow out the excess oil. Yes, the plunger, the parts thats above the frame. Most pics I can find on google are poor and dont show good profile, but all appear near flat, barely protruding. You can see how high up this one rides in the pics I took below. Even with a good deal of force it does not compress enough. There is an obvious recess in the frame and I trust it use to ride in it before they worked on it. Which is why I never had a problem putting together before the AEP was done.

Thanks for the pic. Yeah that's the plunger lever. It's supposed to sit flat in the frame when there's no pressure on the trigger. There's another lever that contacts it and the back of the trigger stirrup to raise it as you press the trigger. Don't force it, give Sig a call. That's not right.

Thanks for confirming the suspicion. I hope its not a trade off for excess over-travel. I cant imagine how they coaxed the slide on there when they were done.

At least with a good reason to go back, I dont feel bad about telling them they need to take care of the two parts of the frame they gacked up the finish on while its there. Was gonna let that go, but no reason to live with it now.

Its arriving tomorrow. While it may be on the high side, they AEP work adjusts the trigger bow to remove all pretravel and the above is considered normal condition following that work. To make it easier would reduce the goodness of the trigger work.

Basically dont worry about preserving the slide underside finish. Force it down enough to use the slide to drive over it once the nose of it is low enough.

I predict a series 80 Colt spacer and safety delete is in my future.
