    My Glock 43 has developed a problem. Once every 3 or 4 magazines the trigger will not reset. The pistol ejects and inserts a new round but the trigger cannot be pulled. i have to rack the slide eject the live round a new round inserts and the gun runs fine until it fails to reset again.
    Any ideas on what causes this issue.

    I have had this problem after installing zev springs. Did you change the springs?

    My first guess is that the trigger connector needs to be adjusted.

    However, more information may be helpful.

    What is the position of the trigger when the failure occurs? Fully forward? Fully rearward? Somewhere 'in between'?

    Please let us know.

    Best regards,

    Bob :)

    Does the trigger connector angle away from the trigger housing as shown below? Also, does the angle of the reset tab appear the same as in the picture?

    If the trigger connector is bent too far 'outward' (away from the trigger housing), it can bind the trigger bar and not allow it to reset.

    If the reset tab is bent too far 'inward' (toward the trigger housing), it may not push the connector far enough away from the trigger bar to allow the trigger to reset.

    Just to be sure, is the trigger bar 'tucked under' the trigger spring 'catch', as shown below?

    It just occured to me that you may want to ensure that the trigger connector is indeed fully seated in the trigger housing.

    Also, a less common issue is that the horizontal extension of the trigger connector reset tab may 'bind' against the bottom of the slide and must be adjusted 'down' slightly, as shown below.

    Clamp the reset tab as shown below and tap it lightly with a hammer.

    Hi, metpol!

    I pulled photo #2 from an 'uncopyrighted' Internet picture search. ;)

    But, if it's your photo, I'll be happy to credit you. Just let me know how you'd like the credit to read. :D

    Best regards,

    Bob :)

    That's fine just appreciate your acknowledgement. You got it from a thread on Glocktalk which I first posted way back when the 42 first came out and I forecast then that this would be the cause of 90% of complaints when owners failed to re-assemble properly.

    Hi, metpol!

    Yep! I just found it again (in Google 'glock 43 trigger spring' Images) and followed the links back to your post. ;)

    Thanks! :D

    Best regards,
