I hate to claim ignorance so early in a conversation but these are the first guns I've owned. I am looking through the manual schematic at the extractor and I have looked at googled images but without breaking the gun down further then the four component parts; frame, slide, barrel and recoil spring - I do not know how to make what I believe is the extractor "play freely." Additionally, nothing free falls out of the slide when disassembled? Sorry for ignorance.
no problem at all, we all started at that point sometime in the past.
you can only check the extractor-play, when disassembling the slide completely. check youtube for some detailed description, there are plenty of good videos there.
the extractor should have a little play and fall out of the slide just by gravity, when the firing pin safety is pushed manually. if not, the extractor might have some negative influence on your extraction and your brass to head problem.

This is a great video that shows a full break down of a glock, although it may not be your model from my understanding or at least for my 19 and 26 it is the same exact steps:
Thanks for the link XPerties. Very informative. Though I'm not ready to break it down to that level yet it is helpful for me in becoming more familiar with the parts. It's a little easier watching that than the schematic in the Glock user guide. Thanks.
08/21/2012 Update
Called Glock to check for warranty parts eligibility on a buddy's Gen 4 G22 w/ test date prior to 10/10/2011 & it did need the part & is being shipped. I asked if the 10/10/2011 date was good info & it is. As far as they are concerned if a gen 4 Glock has a test date 10/10/2011 or after it should not have any known problems.
The only part they are sending is the recoil spring complete assembly. No extractor or ejector. At the end of the recoil spring where it touches the barrel the old spring had a "0" at 9 o'clock, & a "1" at 3 o'clock. The new spring has both those #'s plus a "4" at 6 o'clock.
I watched a video showing how to strip down the slide & it said DO NOT OIL the parts in the slide because it can cause problems of stuff sticking to the oil & jamming the action. When I pulled apart my buddy's Gen 4 G22 it had a little oil in there that I wiped out.
Apex Tactical is full of firearms genius, they should develop their own weapons platforms. Will they be launching an extractor for the .40 and .45 Glocks as well?
When Glock went to the LCI extractor, they also replaced the loaded bearing with a shorter one.
It seems to me that a shorter bearing might prevent the extractor from getting the original tension. I compared the LCI and non LCI extractors and I don't see a difference except a little less mass on the LCI.
Does anybody know why Glock decided that they needed to replace the bearing when they went to the LCI?
I don't have an ejection or extraction problem with my glocks but if I did I would consider trying the old bearing see if it makes any difference.
What do you think?
When Glock went to the LCI they also changed the geometry of the extractor hook. The original hook had the surface of the hook that the side of the case rim rides on parallel to the side of the breech face. The LCI hook changed this and has this surface at an angle to the side of the breech face. As the cartridge rides up the breech face it pushes the extractor progressively farther out away from the slide.
I can only guess, but I think this was to cause the extractor to protrude further from the side of the slide and make the "indicator" more prominent. The force on the extractor spring was probably reduced with the shorter bearing to reduce the downward force on the case rim cased by the angle on the extractor hook. This change only contributes to the erratic ejection problems IMHO.
If you put a straight edge against the surface of the extractor that the edge of the case rim rides on you will see that the original (non LCI) extractor is parallel to the the outside of the extractor. The LCI extractor has an angle to the outside of the extractor. The LCI extractor is not the same geometry as the original extractor.

I'm a new member and just purchased a 19 gen 4 two weeks ago. Had 4 or 5 kick backs to cap and shoulder in 50 rounds of speer 115. I then ran a box of speer 124 with the same results.
Glock suggested having a Glock armorer contact them and they would send a new ejector that would fix the problem. Are they just blowing smoke or does it really fix the problem.

in most cases (not in all) the new ejector did the job or at least is an improvement.
in some cases the polishing of "the step" on the extractor was the key, some also tried non-LCI-extractors and SLBs, or just a different production run of LCI-extractors.
in other cases several things together did the job and some also changed the RSAs
it's a pitty, but it seems that there is no general remedy for all glocks, you'll gotta check your individual glock yourself, but a new ejector is the first step to start with
I have a Gen 4 G19 brass to the head and a Gen 3 G26 with zero problems.
I swapped the extractors and the G26 still had zero issues and the G19 still had some brass to the head. It appears in my case, the extractor is not the issue.
My thinking by switching them the 26 would develop problems and the 19 would be solved, but that didn't happen.
The Gen 4 19 per Glock brass to head has to do with the ejector and new spring system being to stiff when shooting lower power loads. The spring should break in after a few thousands rounds. Mine has the new ejector and shoots all ammo great except the Federal 115 which it throws all the rounds straight back even after 350 rounds. Glock says this is normal and will go away and to stick with 124 or hotter rounds.
Hi guys. I also just registered here because I was thinking about purchasing a Glock 19 as my first handgun. Seems like the ejection issues I have been reading about have not been solved yet.
Pathfinder20 what other brand would you recommend? I hear people like H&K but it is a big price difference, is sig sauer a better option? I'm not familiar with pricing.

I think Glock are telling you Porkie Pies. Does that mean something in American English? It is Cockney rhyming slang for lies! I don't think it is acceptably normal and I don't think it will go away after a few thousand rounds. Even if it did, what is the dollar cost and time cost to shoot a few thousand rounds of Fed 115?
The fact that it does not work with that particular round suggests that the rim profile is not the same as the other rounds you have fired and so the EXTRACTOR is not working as it should to handle all rim profile variants.
oldsarg4 ; Yes they are blowing smoke - sometimes it works but mostly it doesn't.
To whoever very sensibly experimented with swapping extractors between a pistol that worked and one that didn't and concluded that it wasn't the extractor since the problem stayed with the pistol: I suggest that the problem is a mater of fit between slide and extractor. In this case the slide is at fault (too tight sideways or the movement limiter step is too high) but it is easier to modify the extractor than to modify the slide. This is really bad of Glock but it is what it is! The bigger problem is that now there will be incompatibility between different extractors and different slides.

If I had the problem I would remove the extractor and temporarily build up the step by gluing a thin shim (.001-.003"?)and testing it. If that didn't work I'd buy an extra extractor and start removing material from the step .001" at a time and checking the results.
If a person has more than on Glock including one that doesn't misbehave, he could do some comparative measurement of the extractor slot of the slides to see if there is a difference.
The best way to troubleshoot is with two identical guns (many members have more than one) like two G19s so that you can swap the ejector housings, slides, extractors, ejectors, extractor springs, whatever it takes till there are results.
