9UC Now with FTExtract

The FTExt leaving the empty case fully or partially chambered, or both? Sounds like the case if dropping free of the extractor claw before it is hitting the ejector. I would be suspicious of the rounds in the mag being a bit to far out and striking the empty from below as it is being pulled out of the chamber. I did not notice in yoour post that you have tried other mags?

Have you ever fired aot of laquer coated ammo it the gun while the barrel was hot? That can cause problems is some guns if the laquer starts to melt and stick in the barrel. If you have not fired any of it usually the commie stuff, you can rule that out.

You may also want to check the ejector also. if it is damaged, it may not be driving the case completely out, before the next round is picked up.

If you are in a safe area, you may want to manually cycle a mag live rounds through the gun and see if there are any cycling problems with the live ones also. You may want to try a couple of mags. Cycle it slow and fast to see if it drops a round halfway or just doesn't pull it out at all.

I am using both FMJ's and HP's and it really doesn't seem to matter.

Mainly what I'm seeing is the spent case is half way out, the next round in the mag pressing up and the slide has moved forward pressing against the rear of the next round up but, can't advance. I have seen a couple of spent rounds still fully in the chamber and the slide locked open. Those must have been the last round and an empty mag.

I agree, it appears that the case is dropping free of the extractor. I inspected a couple of the rims and found no damage as if the extractor might have pulled through the rim.

I have only tried the two mags that I have; none others. I just tested both mags and they cycle all rounds fine.

I have shot very few lacquer coated rounds so I don't think that applies.

Pictures below as requested. Also a view of the underside of the slide. I did notice a groove on the side opposite the extractor that appears to be worn into the slide. It is not in the newer black slide that I have or it is at least, not as prominent.

Thanks for your help!

SLIDE GROOVE (CIRCLED IN RED)

Thanks for the tip hobbles. When I took the extractor out of it last week I was able to clean the black gunk out of it directly that way.

After further thought, I think another angle on this is that maybe something is holding the spent case in the chamber too tightly. Pancho suggested earlier that it might be lacquer in the barrel so that got me to thinking along those lines.

So, I used my Dremel with a fiber spindle and rouge to polish the chamber interior. I can't say that it's highly polished but, I spent about 20 minutes on it.

I also thought that maybe the recoil springs are too limp thus allowing the slide to move rearward too soon. So I stretched both springs a bit to increase their resistance.

And to top that off, I just ordered new recoil springs, new extractor and extractor springs.

We'll just have to see what happens the next time I'm at the range
