.45 Gold Cup Extraction

RCrosby
Having a problem with a 70 Series Gold Cup, .45 ACP. It throws brass all over the place; far to the right, over my head, into my fore-head, etc.
I suspect the extractor and maybe the mainspring (?). I've read about this problem before, but can't remember exactly what.
Any ideas?
Thanks,
Rob

    Hello there are many things that can cause your pistol to eject in weird directions.Lets make sure we have the correct terms The ejector is the small block that is mounted on the top of the frame on left side the extractor is mounted in the slide and projects into the right side of breach face and the main spring is in the lower back of the grip frame the "RECOIL" spring is the spring that closes the slide after fireing. With that said a series 70 gold cup has a factory enlarged ejection port to help get the empty case out of the gun .if you are haveing trouble the easiest thing to do in this order is replace the extractor with a good quality new one the next step is get a 18 pound spring and "DO NOT" use any recoil buffer or trick aftermarket part. If this does not cure the problem then install a extended ejector . All of these parts are sold thru BROWNELLS . most 1911 problems come from some BUBBA gunsmith installing all kinds of aftermarket parts that don't work together. One more thing ALL semi autos rely on the shooter holding the frame/grip of the pistol firm enough for the slide to function in a full stroke during recoil some times a limp grip will cause eratic ejection.

    May be the ejector. There is information on how to modify the ejector by filing off the top corner but can't find it right now. Check with a gunsmith, he may know how to do this.

    Colt Gold Cups come from the factory with two recoil springs - a 14 pound for light target loads, and a 16 pound for standard loads. Before you panic try installing a standard 16-pound spring. If you fire standard loads with the light spring, the brass will fly all over the place, much like what you describe. You don't need an 18 pounder unless you want to fire hotter and/or heavier than standard loads.

    It's probably not the extractor, but if you want to test it, remove the slide from the frame. Slide an empty cartridge case under the extractor, flush with the breech face. If you can gently rotate the slide in all directions without the case falling out, it's most likely OK.

    Yes, I myself would bet on the extractor, I have had this happen to several guns I have purchased, and seen it on many more, and is typically the extractor being worn or just out of tune, as far as the mainspring I think you have it confused with the recoil spring, the mainspring is a little spring inside the mainspring housing located in the back of the grip that works the hammer, you must match the correct weight of recoil spring to the ammo you are using, typically the lighter the bullet the lighter the spring, you must try to obtain a 3 to 6 foot distance on the ejected brass, to close = to heavy of spring, to far = to light of spring

    Proper tensioning of the extractor is vital to reliability. Too much tension and chambering will be severely impeded or prevented. Too little tension, and extraction and ejection will be weak or non-existent. An old gunsmith trick to test the tension of the extractor is to remove the slide from the pistol, and push a round of ammo up under the extractor from below. With proper tension, the round should be held in place regardless of how the slide is turned, yet when the round is moved downwards from its center position about 1/10 of an inch, the round should drop off.Tension is adjusted by removing the extractor, reversing it in the extractor hole in the slide, and pressing sideways one way or the other to increase or decrease tension

    Hey, thanks ALL! Great responses. Sure appreciate the time put into them and the info given. I'll be trying the extractor and RECOIL spring first, and in that order. Might take me a while to get around to, but I'll let y'all know how it turns out.
    Happy Trails,
    Rob

    p.s.
    If anyone else has the same problem and is interested I found the info that Peabo referred to on modifying the ejector.
    Ref: Brownell's Gunsmithig Kinks, Vol. 4, page 284.
    Thanks again,
    Rob
