New Glock 21 Gen 4 ejects brass all over

Discussion in 'General Glocking' started by TheGlockTalker, Aug 8, 2012.

  1. Hi, still new to this forum.

    I got a new Glock 21 Gen 4 a couple of days ago and wanted to ask if you could help me.

    It's a great gun and I love shooting it but it spits brass all over me. Hot brass raining over you gets tiring after a while.

    Is this just because the gun is still new, shot 300 rounds today, or is there something wrong with it?
    The date on the spent casing is Apr 2012.

    Thanks for your input.

  3. Haven't heard of the gen 4 21's having issues yet, but its probably an issue with the extractor just like some of the other gen 4's are struggling with right now. Seems like a fair assumption to make. Could also be weak ammo, did you shoot factory loads or reloads?

  4. I just started a thread on the G21 Gen4 ejection problems today. Post your info here:
  5. Hope I don't have to send it to Glock......yikes.....hate that kind of stuff.

    I shot both factory (PMC, WWB) and my reloads.
    100 factory and 200 reloads.
    Made no difference.


  6. My GEN4 G21 has a test fire date of April 10, 2012 - serial number STL7??

    I have fired - Winchester, Blazer, Federal & Fiocchi all in 230 GR FMJ and Fiocchi 230 GR HP's.

    No issues with brass to the face -

  7. Uh oh, just a matter of time before the Gaston's Kool aid drinking zealots pop up.

    OP, solution is simple, wear a hat & glasses at all times, shoot homeboy style or trade gun in for M&P or XDm, whichever floats your boat, cause Glock doesn't seem to give a crap their new guns don't run right.
  8. 1,000 rounds through our G21 Gen 4, just from a barrel of misc mixed ammo, absolutely no problems. Hold the gun correctly helps
  9. None of my other guns stop working correctly unless I hold it correctly. Sounds like Glocks are just pretty crappy.

    Hope you can hold it correctly when your life is on the line. :whistling:

  10. Hold the gun correctly?
    You must be kidding.
    I suppose my G21 Gen 3 has been held correctly all these years and so have my 26, 19, 17 and 22 because this has never happened with them.

    Could you tell me exactly what angle is the correct angle with the 21 gen 4's to make sure I don't get burn marks in my face from hot brass?
    I'd really like to know.
    I think the top of the slide is pretty close to being perfectly horizontal.
    In the mean time the only fix I can think of is a ski mask and a heavy sweater.
  11. Sorry to hear you are experiencing the BTF issue with your new 21. I bought a G22 Gen 4 last week and I've put approximately 150 rounds through it with hopefully another 100 later this week. I haven't had any brass hit me in the face yet but I have had a couple of rounds of WWB eject vertically and land at my feet while shooting single handed. However there are plenty of others who have had BTF with their .40s and 9mms recently and I don't discount their stories just because mine hasn't done it. But then I really haven't put many rounds through mine yet. And now you are reporting it with your 21. More I hear about this, the more I think it is a multivariate issue. Could be the ejector, extractor, ammo, shooter's grip, ejection port design, crud built up in the chamber, etc. These are all possible explanations I've seen offered at one time or another.

    There's a rumor Apex will release a Glock Extractor soon.

    I hope that's not like the single stack 9mm Glock.
    Or the Glock carbine.

  13. Or just find a used Gen 3, I wouldn't take a gen 4 if it was free.

  14. The way my 21 is behaving you would know before you're done unloading the first magazine.
    This isn't a sporadic thing where one or two in thousand rounds does something weird.
  15. I wanted to add that the serial is: TAPxxx
  16. or this as well, anything with an L or earlier serial is safe, maybe M, N and possibly O as well.
  17. Two options are sell it or keep sending it back to Glock on your shipping dime.
  18. I have an SHDxxx G21 Gen4, test fired on 11/16/2011 which only acted funny if I loaded ammo on the minimum range. At 850 fps with 230 gr. projectiles, and 950 fps with 185 gr. projectiles, it works like a champ.


    It's been my .45ACP test platform for the different powders and bullets I've tried. Additionally, I haven't had any problems with factory ammo at all.

    I hope that you can get yours working well, because this model is also my favorite of all the Glocks I have.
  19. I heard a rumor that if you sing to a glock every night, in a soft motherly tone. It will eject the brass into a 4 inch squared pattern 3 feet to the right of the gun on dead center.................

  20. That'll work. . . . whatever it takes....

    I will try this tonight before it goes to sleep.
  21. Out of curiosity. What are the numbers on your ejector and extractor?
