Isn't there an extractor also that grabs the hull and the ejector ejects it. Maybe the extractor is the problem. I'm don't know if the newer guns have these or not, been awhile since I've been around shotguns. :dunno:
You are correct, I used the wrong term. Fixed my post.

I bought all three of my sons new 870's and they all had the same issue.
There was a quality control issue in the barrel manufacturing, which left some machining marks in the end of the barrel.
When shells are fired, the brass expands into these machining marks.
All of ours jammed, and all of them were easily fixed.
Here is the issue.
I just wrapped some scotchbright around a drill bit and polished them.
They all work great after doing this.
EDIT:
This video does a better job of explaining it.
Go to 3:30 to see exactly where the machining mark is that caused all of our problems.

I am almost positive I know the problem.This also works great for polishing the barrels.

You can work on them but they are what they are. If they were reliable, there wouldn’t be forums plugged up with fix threads and a million YouTube videos.
I paid $200 on sale at GI Joes and got a $200 gun.

So if I wanted to get a brand new "do it all" shotgun for under, lets say $700, what would you guys recommend?
I bought an 870 and it jams constantly. I tried the polishing and haven’t tried the gun enough to know if it worked.
I bought a stoeger auto and it works flawlessly. I have cases of shells through it duck hunting in mud, cow manure, etc. You can buy them for well under 700.

Well, I did some trading at the area firearms store over the summer. I let my Browning Maxus go in the deal, and got a new 870 Express 3'' in return as part of the deal. I was very glad to have gotten an upland/waterfowl gun worked into the deal. I have been around 870s a LOT, shot one a ton as a kid, never had an issue. Thousands upon thousands of heavy waterfowl loads and I can never remember a failure with my mid 90s vintage 870 Express. This new one does fail. It is randomly not pulling an empty hull out of the barrel. Its not like they are stuck hulls either, as I can pull the barrel off and easily get the empty out with my fingernail. I have tried to file a bit on the barrel where the ejector meets the hull, and still get an ejection failure at times. Its all kinds of shells as well, waterfowl loads, dove loads, doesn't matter. With some research, I guess this is what Remington has lowered its self to. Its not an uncommon issue. But what am I missing? Is there an easy home fix to get this 870 dependable? New ejector? Take it to a gun smith? Thanks for the ideas...
That 870 for sale?

Previous 870 express owner and 870 wing master shooter.
Express would jam on everything from 7.5 shot, #4 turkey and 2.75/3” slugs. Got so tired of it I sold it for $100.

Has anyone seen an issue where you fire an 870, and the pump action sticks and won't come back. After a couple quick pulls it comes back and ejects the shell just fine.
I have an older 870 (probably '91) that I have used and abused and has recently started doing this from time to time.

Yeah, I had that issue. When it happens you need to hold the slide as tight as you can and slam the buttstock on the ground. Obviously, muzzle control is difficult but important.
Most of the time in my case, disassembly and a thorough cleaning would help, particularly all the hard to reach parts in the receiver. There are a couple flat springs that would get junk under them as well as leaves, grass, mud, etc.

I have an 870 express of that vintage that had similar issues as you describe a few years back. One time when I had the gun apart, I noticed the underside of the wood on the pump was rubbed smooth. It seems like I had gotten the wood pump soaked enough times that it swelled and was randomly sticking, then just as you described, after a few tries it would eject just fine.
I sanded down the wood in that area and haven't had a problem since. Hope that helps!

Thanks for all the great feedback... I checked my barrel, and I honestly don't really feel any imperfections to dremel tool out. I feel very shallow ridges, they are tightly spaced, and they are very fine. I'll try and smooth these out, but man, they are very fine, and not sure if they would cause a hull to not eject. Looking forward to smoothing them out none the less. I bought a box of Remington Peters 3" (blue hull) steel to try...Hope the issue goes away!!
Those "fine ridges" can cause a shell to stick, especially ones with a steel head instead of brass...the brass springs back more than the steel and is easier to extract. As far as extractors, there is a SLIGHT difference in angle between the old extractor and the new one...my 0.02$ says that is an issue.

That pin must be worn or gummy or something. 870 pump is one of the most dependable guns God created
Mine is the least dependable I've ever owned. Different strokes and maybe I got into it with a bad batch but I've had more problems with my 870 in 10 years than my Mossberg in 20.

My 870 express has been extremely reliable over the 25 years that I've owned it. I have heard issues about the more recent vintage 870's though
