    My 23 locks open after every shot. I have four mags and it does it with all of them.

    Is there a part or spring that is worn out?

    I'm going to guess you detailed stripped the frame. Then put it back together. And then headed out to shoot the gun and this issue appeared, right?

    There are only 3 ways for the slide to lock open:

    1. Slide stop lever contact with the magazine follower after the last round is fired.

    2. Operator thumb on the slide stop lever.

    3. Incorrectly re-installed slide stop lever.

    I am guessing #3.

    Cure:

    1. remove the locking block pin
    2. remove the trigger pin and slide stop lever
    3. re-install the locking block pin
    4. re-install the slide stop lever
    5. re-install the trigger pin.

    DO NOT ALTER THE ABOVE ORDER!

    ^^^ What he says.


    As this involves a .40, I really can't go into my rant about how the third pin is unnecessary and my "one additional part, one additional source of failure" shtick.

    UH UH, there is a FOURTH:
    The bullet nose hits the lever on the way up. That is what happened on my new EXO G27. A replacement SSL cured the problem. My LGS advises that it is not that uncommon of an issue, the new SSL is the cure.
    Having said that, it sure sounds like his is installed improperly since it does it every time.

    But the .40 uses the same SSL and frame as the 9mm, and the bullet is much wider, creating a smaller margin of error inside. So it can be the bullet hitting the SSL on the way up. Glock also advises that if the trigger pin is not seated properly it can result in PSL. However, that usually works itself out under recoil.

    I was referring to how the 9mm guns don't need that third pin. The .40 cals do, but the 9mm don't. But as both use the same frame, Glock decided to ease production by making only one frame for both. So the frames they produced all had the third pin.

    Which is why early production (say 2002 and before) 9mms only have 2 pins.

    I did not disassemble it before the problem occurred but i will check on the slidestop.

    The top of the slidestop seems to have a small burr on it and it seems to be slightly bent upward.

    I have ordered a new glock extended slidestop and will see what happens.

    I think you found the problem. Probably just enough to catch the stop when it bounces on recoil, which is does on a .40.

    When you take the slide off the frame, does the slide stop stay down against the frame? And, look to verify that the tip of the slide stop spring is visible below the locking block pin like this:

    The slide stop does not stay down against the frame and I do not see that little bump below the block that is shown on your picture.

    I really appreciate the help.

    I have wanted an extended slide sop for some time.
    Do you think the new slide stop will cure this problem?

    If you can not see the end of the spring it is improperly installed. That is the problem. The extended SSL will cure it - if it is properly installed.
    Get out your punch and follow the directions above. Somebody put it in wrong.

    Yup.....or the spring is damaged from a prior (incorrect) installation and slipped out of its correct position.

    Try doing what DannyR said.

    I have shot this pistol two or three times since I disassembled it.

    Could it have just taken a while to show up as a problem?

    You are beating a dead horse. Improper installation of the SSL turns the pistol into a single shot.
    Get out the punch and put it in properly. End of discussion.

    I just wanted to know if it was improperly installed, would it show up immediately or could it take sometime to become a problem.


    End of discussion.

    I'd say it's not likely, but can't rule out the possibility....

    Maybe the spring is gone?
