RIA 1911A1 FS ejection port brass damage

curiosandrelics · Jan 31, 2009

Hi,

has anyone had any experience with this make and model or any 1911 type causing brass ejection marks/damage right to the rear of the ejection port on top of the slide?

Thanks,
C

I always thought that was pretty normal. It's not damage, just brass marks. The brass is just flipping over as it ejects.

Normal. You can alleviate it by changing out recoil springs and doing some work on the extractor and ejector.

I think this is normal for 1911s that do not have flared ejection ports.

Hmmm, I'd say it's normal for a new/tight pistol, but as it loosens up it will usually start ejecting the brass cleaner.

If you haven't changed the recoil spring or ammo you may want to check the extractor tension and adjust if needed. It may be a bit tight.

OK, thanks! It's my first 1911 type. I will see what happens after a good wear-in time, and may have some work done on it.

Thanks again.

Watch where it's throwing the brass too. A smith can adjust the extractor for pretty cheap (should be anyway) if you don't want too. But checking it is easy.

Here's a quick tutorial.

>>><<<
The hook should grasp the case without the tip making contact with the inner part of the rim. Some hooks are deeper than .032 and should be checked to make sure there isn't contact. The front face of the extractor should not touch the case either with the case pressed down against the breechface. If there is any contact in these two areas then stone the extractor down respectively. It may help to stone a slight 45 degree bevel on the inside of the lower edge of the notch between te tip and the body of the extractor. This will help in allowing the extractor to slip over the rim of the case.

Next, with the slide in hand, check the tension of the extractor by slipping a round up under the extractor claw against the breech face; the cartridge should be held in place by the claw. Too little tension and the cartridge will fall out and too much will not allow the case to move while in place. Neither of the two conditions are what is needed. To make any adjustments remove the extractor part way while letting the center "lug" lay against the opening of the extractor tunnel. Rotate the extractor 180 degrees so the claw is facing away from the firing pin tunnel and apply pressure with your thumb to add a slight bend. Try a little at a time and keep rechecking tension until there is enough pressure to hold a loaded cartridge in place without binding.
