    G 19 trigger housing pin slips out

    My first post and I seek the collective wisdom assembled. I have a new G19 gen 4 -- about 750 rounds fired. A few weeks ago while at the range, I noticed that (what I think is) the trigger housing pin was protruding about half way. I tried to push it back in without any luck. Fortunately the range's armorer reinserted it and confirmed it was functional. He commented that he not seen that happen before and that if it happened again I should probably return it to Glock. I used it a few times since without a repeat. This morning while cleaning, while I removed the slide I noticed the pin protruding a bit. It reinserted very easily and seems to be well seated now.

    So the question is whether this is a common occurrence? Any suggestions? Does this necessitates sending it to Glock? Is their customer service up to par?

    I've never had that problem with a Glock. As far as their customer service, my experience has always been excellent. You get to speak to an actual tech when you call, and they get parts to you pronto. Glock is the most responsive manufacturer I have dealt with, and I appreciate that.

    Welcome to the Forum!

    I have a new G19 gen 4 -- about 750 rounds fired. A few weeks ago while at the range, I noticed that (what I think is) the trigger housing pin was protruding about half way. I tried to push it back in without any luck. Fortunately the range's armorer reinserted it and confirmed it was functional. He commented that he not seen that happen before and that if it happened again I should probably return it to Glock. I used it a few times since without a repeat. This morning while cleaning, while I removed the slide I noticed the pin protruding a bit. It reinserted very easily and seems to be well seated now.
    The trigger housing pin is plastic, it is the rearmost pin on the frame. Your gun came with two of these pins, one is attached to the plastic tree that holds the backstraps. That one is the longer of the two, and it will protrude from the frame if it is installed without a backstrap.

    The shorter one should be installed without the backstraps.

    If it does come loose and doesn't want to go back into position:

    1) remove the magazine and cycle the slide to make sure the gun is empty,
    2) point the gun in a safe direction and pull the trigger,
    3) remove the slide per the instructions in your Instructions For Use manual,
    4) push down on the trigger mechanism housing to align the hole in the housing with the holes in the frame,
    5) re-install the pin,
    6) reassemble the gun

    It's been my experience that these pins do not move around much. If I had one that was moving I would flatten one end a bit with a hammer to make it fit tighter..seriously. I always use one of the backstraps, so I use the longer pin, and if it is centered correctly it seems to be captured and held in place by the backstrap.

    Oil in that area of the gun might make it easier for this pin to slip out..there should be zero oil down there.

    So the question is whether this is a common occurrence? Any suggestions? Does this necessitates sending it to Glock? Is their customer service up to par?
    It's not a common occurrence, at least not in my experience. I wouldn't worry about it, especially if I could flatten it a bit and get it to stay in place. If you want more, the replacement parts cost $2.00 (GLOCK Trigger Housing Pin for the G36 and all Gen4 Models-www.glockmeister.com , you need to buy either the short or the long pin, or maybe both.

    Thanks for the welcome. I have enjoyed reading the many informative posts and learning from them.

    The pin I am referencing is #28 on the G19 gen 4 diagram. It is directly above the trigger guard. I believe the one you are referencing on the backstrap is #27 (and was a devil in its own right). I will give the Glock folks a call and see what their opinion is. Thanks again,

    Which drawing are you referring to, and what is the date on your Instructions for Use manual?

    Chris I can't post the diagram link as forum requires 5 posts under the belt before you can post link. It is consistent with all the Glock diagrams for G19 gen 4 I found on google. The gun was purchased in January with a build date of fall in 2013. The Instruction or Use Manual is dated 1/13, however the diagram is for a G17 not a G19. In many respects the parts are similar, but not identical.

    We can use the diagram from the Instructions for Use manual (pp 44-45, see attachment below), the names of the parts and locations are all the same.

    If the trigger pin (#28) is loose I would definitely call Glock. On an older gun that has seen a lot of service and disassembly the frame holes tend to stretch a little, but on a new gun I would say that is unusual and unwelcome. It's a matter of degree, however. With the gun assembled, if you can push that pin out easily, I would have some concern.

    There is a quick fix to this problem: fingernail polish. I have a loose pin on one of my Glocks, and I fixed it simply by putting a few coats of fingernail polish on the pin. That made it fit much better. Not an elegant fix, certainly, but it does work. A harder lacquer or even enamel might even work better.

    One thing I would advise against is trying to flatten the steel pin to make it fit better. First, you're unlikely to be successful because the pins are very hard (I made some nice pin-shaped dents in an anvil when I discovered this..the pin was much harder than the anvil.). Second, doing so might stretch the frame further.

    Thanks Chris. Yes that's the pin. I will give Glock a call. It hasn't been troublesome but guns should never make you wonder. If I can't get it done immediately I will give the nail polish a try.

    Thanks again,

    Mike

    Mike,

    You're most welcome. I wanted to add one other thing, and that is the trigger pin needs to be positioned right in the center. If it's off a little, that's a problem. But when it's right in the center it's captured (I think by the Slide Stop Lever) and it's quite secure.

    Please let us know what you learn from Glock.

    Chris

    Maybe a bit of tightening on the SSL spring will tighten up the capture of the trigger pin ?
