    I was wondering if when you fire a glock, but do not release the trigger if it can create a FTRTB?

    ex. You fire the gun and do not release the trigger but instead continue to have it pulled all the way back. Can this cause the slide not to return to battery?

    Try to get your finger off the trigger before the slide cycles.
    I'm betting you can't do it... :winkie:
    But in answer to your question, no, it should not unless there is a problem with the trigger bar etc.

    With the trigger pulled and held, the hump the engages the firing pin
    safety is a bit higher. I seriously doubt you could pull the trigger and
    release before the slide travels forward. It could contact the bottom
    of the slide just aft of the breech face. This COULD slow the slide.
    What model Glock are we talking about?

    Word has it some 30SF's have this problem due to an out-of-spec trigger bar.

    I thought that you are supposed to keep the trigger depressed, and only release it just enough for the trigger to reset.

    I think a glock18 fires at 1300rpm, so if a 17 or 19 is anywhere in the same ballpark, you're talking about 5/100th of a second for cycle time.

    Thanks for the replies. I was just curious as I was reading about the G30/SF problems and just wondered if any or some small part could be do to that. It seems that the trigger bar sticks up just a bit more when the trigger is pulled all the way back and i was wondering if it could cause a bit of resistance.

    Yep,....that's why Glock released a 4256-1- trigger bar to replace the 4256-1
    Check the height of the frame's slide rails. Some have low rear rails, this has
    also created stiff magazine insertation and slide manipulation.

    With the mag removed and the weapon verified to be empty,
    pull the trigger and hold to the rear. Invery the Glock and look
    into the magazine well and slowly cycle the slide. Watch the trigger
    bar as the slide reaches the "hump" It may bind, also see if the trigger
    bar is deflected to the side when the "hump" depresses the firing pin safety
    plunger.
    This deflection has a lot to do with the trigger bar in the G30sf models
    getting the rub mark. The BEST fix is installing either a 4256 trigger bar
    or the 4256-1- trigger bar. The 4256-1 trigger bar seems to be
    the part that causes all the problems. Again, check the slide rail heights on the frame.

    No - not on a properly functioning gun. However, I had to send my new G30 in because the trigger safety was not protruding as it should and every once in a while after firing, as I was releasing the trigger the gun would make it's final movement into battery (or something was moving into position.) It wasn't really visibly noticable, but you cold feel and hear the gun make a last internal movement as the trigger was released. Glock replaced the trigger (perhaps something else as well) and the gun has functioned flawlessly since. I LOVE this gun and completely trust it. It has never malfunctioned since the repair.

    This is true. This "short trigger reset" is one of the things that makes the GLOCK give up nothing to a 1911 or any other combat pistol-
    That and no manual safety to putz with under stress.

    Yes. This was happening on my 21 SF due to the trigger bar matter discussed above. It's gotten better as the gun is getting broken in. The top of the trigger bar that contacts the firing pin safety is getting worn off with use (as it comes in contact with the moving slide) so that this is becoming less likely to happen. I am also more careful not to hold the trigger back with much force after a shot. This apparently has been the same issue with some 30 SFs.

    I'd get it fixed if I were you, particularly if it's my carry gun. I wouldn't want to have to think about "careful not to hold the trigger back with too much force after a shot" in a stressful situation. FWIW

    That word is correct. I can keep the slide from returning to battery by holding back the trigger. My 30SF is going back to Glock for the second time tomorrow. I've asked that they replace the pistol or frame, refund my purchase price. I'll post the the outcome when I know.

    This is the first thread where I've read that the misalignment of the trigger bar during slide cycling is related to trigger position and/or pressure. Am I correct in thinking that pressure at both the front and rear cause the bar to "buckle" a bit at some point along the linkages? If so, has anyone tried to see whether a reduced trigger pull or a connector that limits overtravel helps/solves the problem?

    That is just funny right there, and I even like my Glocks! :) I do agree the Glock trigger is 'useable', especially compared to some factory 8 lb 1911 lemon triggers, but.....

    *NOTHING* matches a good, tuned 3.5-4 lb 1911 trigger... I've felt some with 1.75-2 lb pulls, but I find them to take some 'getting used to'....and would not trust the hammer/sear engagement thru umpteen thousands of rounds.

    It's all in the trigger bar.
    Do a search for "FTRTB" it's all there,.....many threads and detailed
    descriptions of the problems
