trouble with New Colt 70 series GM 1911 pistol.
I am no pistolsmith or gunsmith, got that out of the equation. A person I know (Curt) has a Colt 1911 GM .45 auto stainless, 70 series, the new version pistol. A friend of Curt has the same pistol, both of them has the same problem. They eject the brass straight back into your chest, head area. An it is denting the brass. On Curt"s gun I installed a Wilson extended ejector. It came with the front already angled downward. I filed a app. 30 degree angle on the right side of the ejector. NO improvement. I checked the extractor, no tension was on it at all. I have the jig an Weigand gauge to set the tension on the extractor. I bent it to pull app. 25 ounces on my trigger gauge. The instruction says 25 to 28 oz. is good. Still no change. Need help on this problem. Thanks in advance. David H.

Is ejector short or extended?
Is ejection port lowered?
If extractor not contacting the case rim correctly the tension adjustments do not always help.

Trouble with ejecting on 1911
Jon, the ejector in a new Wilson extended. I will try a new Ed Brown extractor in the gun. I do not understand on what you ask on the ejector port lowered. . David H.

A lowered ejection port is approximately 0.50" high from bottom edge of the slide.
Should be interesting to see if the new extractor does the trick.

ejection problems
Jon, I had a Brain Fog moment there, when you mention the ejection port. I had showed Curt how my wadgun an hardball gun ejection port was lowered. He did not want to go that route on his gun. So I will try a different extractor ,if that does not help. he can just live with it. That is all I can do. Thank you Jon. David H.

It is possible that if the brass ejection is too low it will carom off the inside bottom of the port and bounce up (into your face). Paradoxically this condition is solved by filing the ejector nose (bevel the top edge incrementally) to lower the contact point and raise ejection to clear the slide.

Re: trouble with New Colt 70 series GM 1911 pistol.
This site has been a great resource for me as it pertains to my pistols, reloading, etc. I was having a similar problem until someone posted the 2014 photo by Jerry Keefer, showing the proper arrangement of an extractor tip in a 1911 pistol. I have a SA 1911A1 in .45, SA RO in 9mm, and pre-70s Colt NM in .45. They each use a different extractor for consistent operation. I spent a bit of time and money finding the best extractor for each pistol, mainly for total length and proper fit inside the extractor hole, to enable that slight "squeeze" that holds a case against the breech face, and yet does not make contact with the case anywhere in the extractor grove. For some extractors, no amount of filing would work and I was afraid that I would be weakening what was left. I learned a lot but I can honestly say that I feel pretty competent fitting an extractor in a 1911.

Square the ejector nose on your extended one.
I use the EGW std. Extractor on every pistol I build..shortest one out there without cutting your own.

BTF... brass to the face. I have Glocks. lol
I was running a 17 dry and that seemed to help for a little while but now it's back.

Not exactly a Series 70 Colt is it. You might want to start a new thread but that might be frowned upon in a bullseye forum.285wannab wrote:BTF... brass to the face. I have Glocks. lol

Colt or Glock. My point was that slide speed has an influence on how brass leaves a gun. That's my opinion Steve.

Since you have plenty of good advice on the extractor, two things still come to mind; 1) Be sure the ejector is not too long. 2) Be sure the slide spring is not too light.
