I'm final fitting and fine tuning a build and am working on the ejection area as I'm still having a bit of trouble getting the gun to eject well. I custom fitted an oversized ejector from brownells and it seems to be working fine.
Now snap caps pop out quite well, but live rounds keep getting jammed up right below the ejection port and lip of the barrel. In this particular build, I noticed that the extractor fits really tight (need a punch to pry it out) compared to my other builds where the extractor moved as freely as the firing pin stop allowed it to. Could this be causing problems with the ejection? Should the extractor fit tightly, or should it be able to move?
Snap caps eject well only if I pull the slide back rapidly, but when doing it slow, they too get jammed up as well, while live rounds don't eject at all. Also, the last snap cap in the mag will not eject at all. Any suggestions will be appreciated on top of the question regarding the extractor.
Sometimes when I work on something too long, the obvious doesn't occur to me. I went to Blindhog's site and then it dawned on me; I need to polish the damn thing and check the tension. After about 5 minutes with some 220 emery paper, it's working beautifully now.
I'm still wondering though, does it matter if the extractor moves around a little or should it be a tight fit?
Your on the right track by polishing the extractor and adjusting its tension. How much it moves around is proportional to where the hole was drilled in relation to the firing pin hole. In other words do not worry about it flopping around as long as it tensions the side of the round the right amount. Also be aware anytime you place a new long ejector in a gun it might start ejecting the round so soon a live round might not eject properly. To fix this problem you would either do one of two things, shorten ejector until live round ejects, or mill the ejection port slightly further forward to help facilitate the ejection of a live round.
Thanks for the comments Blindhogg! It's working now, but in the exact opposite as it was. Now when I pull the slide slowly back, it ejects fine. As soon as I pull it fast, the round jams in there.
I now notice that when I pull the slide back fast, the extractor actually lets go of the round (at what point I don't know). That's what's causing it to jam in there. I did try increasing the tension a little, but I'm afraid to bend too much. Any other suggestions? If I need to increase the tension then I will... I can always buy another one if I bend too much.
Well, I shortened the ejector a little more and tuned the extractor a hair. It ejects flawlessly now, with the exception of the last round in the magazine, which jams. When doing it slow, it's fine. Otherwise, the same problem. The extractor lets go of it and it jams on the last round. This is driving me nuts!
This is usually an indicator of inadequate extractor tension, or grip. compare your extractor to a PROVEN good extractor. Sometimes the dimensions and or angles are not right. Also, mike and compare your ejection port. Is is it flared at the rear, ala Gold Cup? Are these factory ball rounds, or what sort of ammo? Don't use reloads to evaluate a gun. They introduce a questionable variable into the equation, for no reason. Also, be sure to use proven good mags for any such evaluation. The reason the last round is a problem is that there are no live rounds in the mag 'guiding" the ejected round back to the ejector.
Also, measure the breechface, both to edge of ejector and edge of extractor hole, diameter of extractor hole, and look for burrs or machine marks on the breechface.
Of all those suggestions, I believe the one about the extractor tension would make a bit more sense as the only problem I'm having now (as per my last post) is the ejection of the last round in the magazine.
All other rounds before that one ejects fine but the extractor lets go of the last round ONLY when I pull the slide back quickly. When doing it at a slower rate, it works fine.
Has anyone had a similar problem with the last round not ejecting properly? Is this something I'd have to really worry about later on down the line if I chose to leave it as is? I don't have any empty casings so I can't tell if it's simply because a live round packs a bit of weight.

I have had this problem & I can understand how frustrating it can be. The problem was fixed for me with a new fresh mag spring. That or stretching the one you have now to buy yourself a lil' extra preassure for a little while at least. As wasntme suggested, a good mag will eliminate that part of the investigation. Another thing to do is the extractor test with an empty brass, but if this is a last round only problem - I'd guess that's already been done? See blindhogg's site for a better write-up on that issue.
One more thing I should mention, regardless of how fast or slow you cycle that slide - if you do it by hand - it still doesn't do justice to how it really works when live fireing. You may be surprised how that thing does at the range & you may want to give that a try before you spend much more money or labor.
I see you have gotten further than you did yesterday. I am quite sure the reason you were having problems yesterday was because your ejector was too long. When ejector is too long front of live round hangs up on the ejection port when attempting to eject. Anyway as for the last live round hanging up I would not sweat it as the goal is to eject spent rounds. Just shoot the hell out of it and let us know if everything is working out alright, if not we will get you back on track.
Well, it's working a lot better than last night as I tuned it just a little bit more today. I also took emery to it just a little bit more and it's all good. I do still run across the last round problem but only on about every other try.
As suggested, I'm going to shoot it like crazy and keep shooting as long as it allows, until I run out of rounds that I bring. Thanks for all the advice and I'm really looking forward to taking this out.
All that's left is to coat the gun (teflon). Hoorah!
BH, you meant that the EJECTOR is too long, right? Not the extractor?
Yep your right I meant to say the Ejector instead of the extractor.
