Thread: Glock 23 bending lip on ejected brass

  1. Glock 23 bending lip on ejected brass

    My Glock 23 is putting a large dent in the top third of the ejected brass. I am not seeing any stovepipes yet, but obviously potential jams is my big concern. Should I replace the ejector, or is this likely to be some other issue?

    Can you provide a pic of the brass? I have a sub-2k in the .40 cal flavor and I have found that shooting the 180 grain bullets the brass have no dents. However, the lighter bullets of 155 grains do.

    Is this a brand new gun never fired or did it just start doing this?

    New or used firearm? Has the recoil spring been replaced?

    Check the brass to see if the ejector is slipping off the rim or is worn...

    As indicated above, several eight-by-ten color glossy photographs with circles
    and arrows and a paragraph on the back of each one explaining what each
    one was would be helpful.

    I'll seek cover in case it goes badly..

  5. This is a used Glock. This problem just showed up recently. The gun did not bend the brass when I purchased it. This G23 was a city police detective's service weapon. They switched to S&W's. I doubt that the recoil spring has ever been replaced. I cannot find any marks on the expended brass that would indicate that the ejector is slipping off the casings. I forgot to mention that I shoot 180 grain and usually Federal, because I get a decent price on Federal ammo. I will take some pics of the brass as soon as I can.

    I have noted the same thing with a 1911A1 that I have. I caught a few before they hit the ground, and found those weren't bent. They were getting bent when they hit the concrete.

    May not be the same thing, but it's worth checking.

    You wrote "just showed up", was that with the same or different ammo type used now vs. previous usage, i.e. different gr weight or type/mfg of ammo?

    I like to root cause issues rather than perform the SWAG method of problem solving. The SWAG method is expensive in that parts are replaced sometimes needlessly...

    I got in the habit of looking the brass over after unloading it. I grab a handful and align and orient a few as they were in the chamber when fired by looking for the marks made by the extractor, ejector, and firing pin... It's kinda interesting and will indicate possible causes of anomalies. I've not perfected this, but enjoy the practice...

  8. I have been shooting the same ammo since buying the G23. I would estimate that I put 300 rds through it before I noticed the dented brass. When I first noticed the "denting" I was shooting outside at a rural location and the brass was landing in grass. I will try "orienting" some of them to try to understand what side of the brass is denting - relative to the ejection port, etc. Thanks for all this help guys! I know it's hard to develop a diagnosis when you can't see the patient! I'll post some pics of the brass as soon as I can.

  9. When have you removed and cleaned the extractor?

    How many rounds have been through this gun? As another poster said, you may need a new recoil spring.

    Have you had any rounds fail to eject?

    Could you be limp wristing a little?

    You don't have a habit if dropping the slide on a single round in the chamber, do you? I used to do this after loading a mag to maximum capacity, then one in the chamber drop the slide on the round, then insert the mag. I read that this is a good way to bend or break an extractor.

    I debugged an ejection issue on a Colt Officer's ACP that I got in a non firearm item trade.
    I kept getting a cartridge that would end up not ejecting, but not a stovepipe. It was a matter of studying the brass and noting the consistencies in the ones that failed to eject.

    It was the combination of the worn and poorly tuned extractor (series 80) along with a pair of slightly deformed factory magazines. The brass in an automatic pistol can act like the "CHECK ENGINE" light in an automobile and warn you when things are not as they should be. It requires some reading and interpretation...

    Here is some of my brass I shot today. I have circled the areas where the brass is "nicked". These were shot from my sub2k. I might add that I have fired more than 600 rounds through the gun and it has never jammed, failed to load or extract the brass from the chamber. Look at these photos and see if your brass is similar.

    The heaver bullet weights don't seem to be a problem which leads me to believe the spring is tight and maybe throwing off the timing a little due to the bolt closing faster than it was designed too. The "nicking" of the brass seems to be going away the more the rifle is fired.

    I would try a different spring on your G23 and see if that corrects the problem.

    I bought a Spikes Tactical 22LR conversion for my AR-15 and the kit came with two springs. The instructions said the springs may require tuning. At first it was terrible. Could not find ammo that would function without jamming or producing stove pipes. After trimming one spring and experimenting with several different brands of ammo the CCI stingers and mini mags worked the best. I have also had good luck with the Winchester White box ammo too. But the Wally World store I shop at doesn't seem to be carrying it anymore. The Federal economy pack was the worst with stove pipes almost every other round even after "tuning" the spring.
