Semi auto, 9mm, clean, newish SR9 pistol.

3 or 4 in a thousand rounds fired, not an epidemic for sure. The first 2 certainly could be limp wristing as I was trying to "relax" while shooting.

The last one bit me in an IPDA stage. that really puts a bummer in the time...

Not a stovepipe, but like one. New round is partially in the chamber, but the empty is still in the gun, sitting directly above the new round, keeping the slide from closing. Empty is facing forward, just like new round.

Drop mag and rack it, all is fine.

What do I need to do?

thanx
 
Malfunctions occur. As long as the rate is low, 1 in 500 is tolerable, 1 in 20 needs work on the gun or ammo. In both bullseye games "alibis" are allowed once or twice in a match unless they are caused by the shooter, otherwise it is "clear it and go".

all guns malfunction eventually.
 
Alibis may be allowed in some shooting disciplines, but not in the ones in which I compete.
Clock is running, and if rounds are saved, too bad, so sad.
 
You might want to pull the pin and remove the extractor so you can clean out the recess. I did that on a CZ a while back. I was shocked at the amount of packed in grunge in there despite supposedly flushing it out with a can of brake cleaner. Apparently the shot of cleaner wasn't doing much at all. Another spot to check is the notch alongside the chamber where the nose of the extractor fits when the slide is in battery. If it's a dead end shape it can pack grunge in there. If it's a simple open sided slot then not so much of a worry.

At the same time inspect the extractor for shape and see how well it fits the rims of the ammo. The shape of the hook might be wearing out so the hook is having a harder time of holding the rim for extraction.

It might be worth changing the extractor spring while you're cleaning out that area if the gun is older. If the spring is softening up or compressing to a shorter shape it could be that the extractor pressure is getting too low.
 
A real thorough cleaning is always the first thing I do when that happens to me, most times it solves the problem. If it still continues you have to look at what may be worn such as the extractor. or other related parts.

Did you modify or change any of the springs etc?

It's an SR9 - it's not a target pistol, it should never malfunction when used as a target pistol - one of the trade offs you make in buying this type of pistol is that you give up the X ring at 50 yards, to gain reliability at 15 yards. It is absolutely unacceptabe for what is designed as a combat weapon to fail when used as a range gun by owners who are only allowed 2/3rds capacity magazines and most of whom show up at the range with a clean pistol. The only way these guns should have issues is if the ammo is bad, the maintenance is bad, or something's broken. There are a few guys here with comparable guns getting into the 30-60,000 round counts, with only ammo related failures. My own M&P is running almost 10,000 rounds between ammo related failures, and has had zero gun related failures in close to 40,000 rounds.
 
ok, its nearly new, has roughly 1000 rounds thru it, so I hope nothing is worn yet.

factory ammo. It hasn't failed with reloads yet. AE 115grn FMJ

the clock still ran, trust me...

there was a S&W M&P9 and a CZ(both near new as well) that jammed that day too.

its bone stock, except for some minor smoothing in the trigger area and a bit more in the striker channel. I can't see that doing anything in this area.

I hope I can just clean it and get it working again.

And I agree, this pistol should never fail, except for human error or ammo related.

Is it possible that the AE 115grn ammo is not strong enough to keep the slide back long enough for the spent casing to get out? Never had this issue with 124grn, two different batches.

Thanx Bruce, I will look into those areas.

Sorry, but if you gun won't cycle all commercial ammo reliably, its a lemon. I often run the same ammo through my Glock with a 20lbs recoil spring without issue and have run up to a 24lbs spring successfully. I'm gonna say your recoil spring is between 15-18 pounds tops. I highly highly doubt AE/Federal ammo is the culprit. I'm gonna say you have some out of spec parts or worn parts. Start with a thorough clean and inspection. If your mags aren't numbered, do so and keep track of which magazines the failures are occurring with.

Take out the extractor and "sharpen" it... a few strokes from a file does wonders...but not too much...! When you drag the extractor across your hand it should be sharp after a couple of passes with a file....guaranteed that hook will grab the rim next time...

So you're saying you're ok with a firearm that doesn't run right straight from the box? Ok, got it.

Extraction was/is not the a issue guys, he says its fully extracting, new round partially in chamber, fired brass not EJECTED .
Don't file ####, on your gun, yer gunna ruin it.
leave it alone . there is likely nothing wrong.
you got a perfect, classic example of a occational limp wristed round .
It could possably be a gummed up with dirt and crap .or it could even need a bit more break in .
If its not related to either of those issues .......and something is wrong .than its either your Ejectoror magazine.
Don't start filing.

I know its not supposed to do this, but there is no warranty, and even if there was, I would not want to ship it to Prescott Az and deal with that crap. I am hoping to get it sorted out with you all. :)

I did clean some really crusty crap from behind the extractor, in the cast part of the slide. As well I found a little bit behind the hooked blade part of the extractor. cleaned up both, also cleaned off a small burr in the casting of the extractor blade.

Not sure what to do with the ejector. it seems to be functioning normally, but then again, the gun has only failed those 3-4 times in a thousand rounds. And the first two were in the first 50. so nearly a thousand with only 2 failures. its not like I can make it fail on command to reproduce the problem, then try something and then see if it fails.

mixing two types of ammo? thoughts on that? I had known good quality reloads from a reputable reloader who sells tons of ammo mixed with AE 124grn mixed with 115grn. nickel plated brass cases mixed with brass cased. both round nose fmj.
 
If you cleaned out some crud from behind the extractor, theres a good chance you solved your problem.
Imo mixing brands of ammo shouldn't matter but some guns seem to work better with certain types.
I have one that only likes Norma ammo, anything else and it shoots off.

Don't touch the ejector. If it isn't bent(anymore than when it was new if it was bent) and its not cracked, chipped, or otherwise defective then I would say its fine. AS posted above, your clearing the debris from tight areas around the extractor could very well have solved the issue. Make a small correction and shoot, then repeat if necessary. Changing multiple criteria at the same time may solve the problem, but it won't help you determine what the cause was to begin with.
