    Have a relatively new (few hundred rounds) G36. The problem is that, when it's fired and the trigger held back, the slide fails to return completely into battery. When I release the trigger to the reset point, the slide moves forward into battery. GLOCK looked at it, switched the recoil spring assembly, and sent it back to me. The RSA was virtually new, so maybe the old one had an issue, but the same problem happens with the new RSA, so I don't think that was the issue. What is there that could cause the slide to hang back like that? I am trying to imagine what moves or changes inside when the trigger is held back, as opposed to releasing it forward, to see what (if anything) I can do about it. Any suggestions?

    look at the trigger bar, does the part number end with a "-1" or a "-1-"?
    the -1- is the lastet trigger bar to correct that problem. you will probably notice a rub area on the trigger bar somewhere

    I think the G36 uses a different trigger bar than the G30.

    I wish I could use another trigger bar, but DLL9mm is correct. I do notice some shiny areas on the arms of the locking block, indicating that they are rubbing something that is polishing them. I added a bit of lubrication to the shiny areas of the arms, and will see about that next range session. Of course, things might sort themselves out with use and the "break in" period that GLOCKs do and do not need (depending upon whom you ask).

    something does not sound right; something is not right.

    Send it back or have an armorer look at it.

    Function the weapon and replicate this problem with an Armorer looking at it. It sounds like the trigger assembly and/or connector is hanging on something. Weird.:dunno:

    My gut feeling was RSA, but then my ADD let me read the next line. Post on what you discover. Be safe and good luck.

    I am an Armorer, and it already went back to GLOCK once. They did their standard "switch out the recoil spring assembly, test fire, send it back" thing. I will bring it back out and see what happens with lubrication on the shiny areas of the locking block, trigger spur, firing pin safety, and anywhere else I can imagine the pistol is rubbing.

    Sounds like an out of spec trigger bar.

    Ensure the G36 is unloaded and leave the mag out.
    Invert the weapon, magazine well toward the ceiling.
    While holding the trigger to the rear, slowly cycle the slide.
    Just as the slide gets to about 1" from the fully forward position,
    Pay attention to the trigger bar as it nears the slide's breech face.
    Also watch as it trasnitions over and depresses the striker safety plunger.


    Does the trigger bar flex to the side at all? If it does, the trigger bar is out of spec,
    or, the slide rails are too low in the frame.

    Lastly, remove the slide lock and inspect for any burrs or sharp edges.
    If those are found, replace the slide lock.

    Apologies, I did not know you were an armorer as well. Without it in my fingers, I am stumped.

    Are you by any chance using a NY1 trigger spring?

    No, the standard 5.5 lb spring. I brought home my orange half slide cover plate so I can take a better look inside. Will try to do that this weekend. I will also try that upside down trick mentioned by faawrenchbndr. I need to see what is going on. I believe that the trigger bar is not to spec, but can't understand why GLOCK didn't catch it during the service? Maybe it's time to simply order a new trigger and take my chances with a new one being right.

    Oh, and no apologies necessary GSSF17. How could you know?

    OK, based on what I could see with the orange slide cover plate installed, the connector does not pop back into position until the trigger is released to its reset point. I am not sure what happens with other Glocks, since that's the one I have with me. Basically, everything else looks normal from back there. I could also see no problems when it was held upside down and cycled. If the connector is supposed to snap back into position as the slide's cam moves the connector tab, then it is failing to do this.

    That's normal. That is exactly what the reset point is -- the point at which the connector can pop outward and again reconnect with the trigger bar (and cruciform) to guide it downward with rearward motion of the trigger bar.

    OK, then I am left scratching my head. Back to the range.
