View Full Version : Posible to tune ejector?

While at the range today I noticed that my fired cases seemed to land in all sorts of places. Is it possible to "tune" the ejector system so that the empties land in an area that is some what uniform in its location?

Yes, it is possible. But first you'd best tend to that extractor because I suspects it's clocking on you. After you get a new, fitted firing pin stop in there, your ejection trajectory will probably be ironed out to your liking. And if not, you can tune that ejector to suit.
I think Tuner has posted a good set of instructions on how to do it.

Whenever I have call to work on an ejection trajectory issue...the extractor is the first thing that I look at. Hook depth from the tip to the tensioning wall...tension on the case...Hook shape/geometry, etc.
Slide travel can and usually does have an effect. Is there a shock buff in the gun? Is the gun oversprung...causing even a small amount of short cycle?
THe ejector is the last thing on the list, and normally just altered for that last bit of fine-tuning. It doesn't require a radical change to cause a big difference in the ejection.

I've seen bullseye shooters get their ejector trimmed and aimed so that all their brass came down within a 2 ft circle at their feet.

Thanks all. New to serious shooting of the 1911 although Ive "played" sort of speak with them for years.
The gun is a CC XSE a couple years old with 1175 rounds shot thru it.
I changed the main and firing pin spring with a OEM poundage set from Wolff at 1000 rounds and installed a Wilson shok-buffer. The gun seems to function flawlessly with the exception of the brass being scattered about. I would think (Im a AR shooter at heart and have cut the ejector spring which results in a pile of empties close to my position) that I should get the same pile of brass with my .45 but I may be wrong.
Is there something that I can inspect to see if whatever it maybe is not "fitting" properly? I dont know what that may be but perhaps you all could point me in a direction.
If you need to know additional info let me know.
Thanks you all.

Hi
When you see a 45 dropping brass as somebody's feet, that's a good indication that they are shooting low power loads. With full power loads a six to ten foot "toss" is pretty normal.

First of all, you may want to check your extractor (as it's been mentioned) to make sure it is not clocking (turning inside its tunnel a little). Take the slide off the pistol and try inserting a case under the extractor claw from the bottom of the slide. Watch closely to see if there is any rotational movement of the extractor. You can look at the back of the slide, where the rear edge of the extractor is, if you see it turning at all, you need a new firing pin stop to stop it from turning.

Right.
It was when I was doing bullseye shooting and the norm was/is light loads. Even so a stock ejector will kick 'em out unpredictably but a little filing here, a little there, and you don't have to spend much time chasing brass. People mark their brass with different colored markers because it gets all jumbled with the brass of other people on the line. when you have to get out and change targets, pick up brass and then try to get back to a shooting calm for the next string you do whatever you can to lessen the hassle of a hassling situation.
OTOH, I've known of bullseye shooters who try to aim their ejectors so their brass goes down the next guy's neck in order to throw him off his concentration :)

I am sorry if this is a dupe post, but I think I didn't properly "submit" it. SO-
Unless the extractor is 'falling out' loose, all one has to do is look from the rear (hammer end) and see how the extractor lines up with the hammer slot. Fast, easy. Normally, the clocking extractor rotates clockwise, as viewed from the rear.
