    Hi there just bought a Glock 20 and first thing i noticed was that with normal factory 10mm rnds the brass doesn't eject far, but no other problems. Then I tried Buffalo Bore 220 hardcast and the slide came back and caught the brass every time. I have a 24 lb recoil spring in the mail. Any suggestions to get that brass to throw better ?

    I don't understand what's happening (your description- "caught the brass") with the buffalo ammo-- does it eject the brass?

    What's your idea of better, and where do you want the brass to go?

    You need a lighter weight recoil spring than what you have in the gun for the Buffalo, or just carry factory ammo.

    Why did you pick 24# when the factory is 17#?

    It seems to be ejecting factory ammo lightly, and the BB ammo not at all...thats why the slide comes back and slams the brass between the slide and barrel. I ordered the heavier spring because I thought It might slow down the slide movement giving the brass more time to exit the chamber area.

    I think you are going the wrong direction with the spring. Any way the recoil spring is not already stock?

    Check the condition of the extractor claw edge and the tip of the ejector too. It is possible that the extractor plunger spring, or the spring loaded bearing inside the slide is affected?
    Are you using the correct mags?
    This is not a caliber conversion is it?

    If you send this to GLOCK, they will replace all of your worn parts for the cost of shipping it to them.

    More information for sure, otherwise to hard to say what might be going on. What generation is the gun what is the number on the ejector (not the extractor) magazines old or new?
