:I have a Sig xo which started doing that. RO suggested replacing the recoil spring but that did not cure the problem. I Also have a Sig Carry 1911 which doesn't do this at all. So when you find out...let me know

[Barbarosa]

Did it just start or has it always done it? Did you take it apart and then it started? Could be a damaged extractor or the extractor is turning (clocking) which would change its angle. If that's not it check your ejector to see if it is damaged. If it looks OK google "1911 ejector tuning" and bone up on the subject.

The cases are just barely clearing the ejection port as the slide comes forward and pinches the case for a moment.
This is the reason for the relief scallop cut at the rear of a modern 1911 ejection port.
I'm not sure what kind of 1911 you have or what the ejection port size is.
Original mil-spec ports are rather small but if the ejection is timed right they work fine.

If you are using a shockbuff then that may keep the slide from going all the way back.
If the slide does not go all the way back the ejector may not be able to give the fired case a good kick out of the gun.
Also, an incorrect recoil spring may coil bind and stop the slide from going all the way back.

If the extractor does not have proper tension or is spinning, this problem can occur.

Loose or bent ejector tip can be a problem.

Lazy or sluggish ejection should be tracked down and fixed.

What model 1911? Do you have a standard or extended ejector? How many rounds thru your gun? Could be a combo of worn main spring and recoil spring, or if you are using shok buffs like ojisan said. Another possible culprit is an extractor that has too much tension.

I also have seen this when the recoil spring is too powerful, and causes the slide to come forward too fast, slamming the case into the forward part of the ejection port. Any brass marks on your slide?

Thanks for the the help and suggestions fellow Calgunners..these were fired through a Para lower build kit with a Brazilian military slide/ dust cover 70series. Recoil spring is from Wilson combat flat spring with a buffer insert.

If your ejection port is not lowered/flared, this can happen.

[JustEd]

^I have a Sig xo which does is and the port is both lowered and flared. Never did it when new, no one yet has had a good solution for it. My other Sig 1911 doesn't do thid but is fairly new.

My Colt XSE did something similar before I modified it. I did pretty extensive work, but I believe what contributed the most was a heavier hammer spring, and tuning the ejector.

[ojisan]

I use a shortened Commander ejector with my 5" slide.
The long nose on the Commander ejector allows it to be easily shortened until the ejection timing is right.

Good info. Tagged

My series 70 Colt MK IV does it all the time, always has. So I only use brass that is scheduled for it's final tour through that piece. Most of the time, it's service is relegated to .22 action with the Colt conversion I have for it. I know it doesn't solve your problem.
