I am still having feed issues and it's throwing spent brass in my forehead. I am getting quite tired of it.

I've polished my feed, polished the barrel feed, and still, every once in a while (even after completely removing the OEM mags from the picture, using wilson 8 rounders now), I am still having initial feed (first round) issues.
 
There are a number of things that can cause ejection issues. However you mention that you have feeding problems as well. I would suggest you direct attention to the extractor.

Cheers

Sounds like you are having unrelated issues. I would agree with recurving the extractor for your extraction problem or even replacing it. You said you are having feed problems as well. Are you saying the first round after you shoot is misfeeding or releasing the slide on the first round is an issue? Secondly what ammo have you tried?
 
I have decided to use my 30 years of working on 1911 pistols, to see if maybe i can help diagnosis the problems you describe. 1911 issues are generally easy to correct, by beginning with the process of elimination.

Feeding problems:
1. Check the lower edge of the "barrel throat" to make certain it is not hang over the top edge of the frame "feed ramp"
2. Has the "chamber break-over" ledge at the top of the barrel throat been gently radius polished.
3. Has the chamfer on the underside of the barrel hood extension been polished?

Ejection problems:
1. Examine the inner edge of the ejection port to see if any machine burrs are present. The chamfer edge on the bottom edge of the port needs to be polished.
2. Examine the tip / nose of the ejector (not the extractor) for any obvious defects. The edge of the right front edge needs to be at a 45 degree angle to the tip & polished.

Extractor:
1. Check for proper tension.
2. Examine tip for any burrs or damage.

I will stop at this point so you can check these items.

There is no overhang of the barrel onto the frame's ramps. The barrel ramps are polshed, as is the frame's ramp

2. Has the "chamber break-over" ledge at the top of the barrel throat been gently radius polished.
yes, it has a gentle radius, and is also polished (recently polished it with a dremel)

3. Has the chamfer on the underside of the barrel hood extension been polished?
yes

Ejection problems:
1. Examine the inner edge of the ejection port to see if any machine burrs are present. The chamfer edge on the bottom edge of the port needs to be polished.
There are no burs, but it is not polished. However it is smooth

2. Examine the tip / nose of the ejector (not the extractor) for any obvious defects. The edge of the right front edge needs to be at a 45 degree angle to the tip & polished.
There are no burs or dings, and top leading edge has a 45* slope, which doesn't appear polished

Extractor:
1. Check for proper tension.
has been tensioned by Colt several times and I have not touched it

2. Examine tip for any burrs or damage.
No burs or dings present

Boosted: In my experience, the problem of empty cases coming straight back to the shooter is usually caused by an extractor that is not profiled correctly. Reference Kuhnhausen's book, or see the link below, for details including line drawings, but factory extractors are usually not shaped properly.

If I am correct in my diagnosis, you need to remove the extractor from the slide and reshape the tip per the instructions. An OEM extractor that has too much "hook" to it will "hang on" to the empty case's extractor groove a little bit too long as the case is pushed forwards by the ejector. This causes the case to rotate 180 degrees and be pulled back toward the shooter. At least that's the theory, it all happens so fast the naked eye can't see it.

The properly profiled extractor has a tip shaped just so, with a rounded/beveled and polished profile at the front end that permits the empty case to smoothly rotate approx 90 degrees before being propelled by the ejector out the port. Normal ejection pattern for my tuned Gold Cup is about 4 o'clock and 8 to 10 feet distant with hardball-type loads.

When you have it right, don't forget to bend the extractor in such a way that it grips the fired case with the right amount of tension, just enough for a firm grip, but not too much to interfere with easy engagement of the loaded round as it comes up from the magazine. I profiled my factory Colt extractor about 25 years ago and haven't touched it since. Old John definitely knew what he was doing. - CW

You change the ejection angle by changing the ejector. The angle of ejection depends on where on the case the ejector contacts when the case comes back to meet it. To eject at a flatter angle, you want the ejector to hit higher on the case.

(On rereading the above, I can see maybe there could be confusion. By "changing the ejector", I did not mean "replacing the ejector"; I meant changing its angle with a file or stone.)
