    The locking block pin on my G27 is backing out during firing, any way to stop that?

    The locking block pin has two grooves in it, when installed correctly the left groove captures the slide stop spring preventing the pin from moving. I would check these two parts for proper installation or wear.

    Have you detail stripped the gun alot? If so, you can reem out the pin holes over time, making the pins loose. I've seen a few people use a drop of clear nail polish on the outside of the pin to hold it in place. As the other person said, make sure they are installed correctly first.

    Try again! The locking block pin is the #1 pin. It does NOT have any grooves in it. It's the #2 trigger pin that has the grooves you mention. I'm wondering (Actually I suspect) if the OP has inadvertently switched the #1 and #3 pins?

    If this isn't the situation then simply varnish the #1 pin about its enlarged ends and the problem should be cured. Still I think the OP should check for a mixup BEFORE doing anything else. If there's a plastic pin in the #1 hole then a mixup has definitely occurred. OK! :)

    I rechecked the pin this morning and I definitely have the metal pin in the correct hole. The plastic pin is on the grip. I got the gun used and broke it down to clean it and it was filthy. Not sure if the previous owner had ever done that as it was a real pain getting the large pin out. I almost couldn't get it out. I used Gunzilla to clean it, could that be a possible cause?

    Did you follow the Glockstore video and use a hammer to drive out the pin?

    Is the gun relatively new? If so, call Glock and speak to the Warranty Service Department. This has been reported with some brand new Glocks and in some cases they replace just the pin, in others they replace the pin and the locking block, and in others they replace the whole frame.

    I've heard of a weak slide stop spring rarely causing the locking block win to walk out, and once the slide stop is replaced it stops walking out. That doesn't make much sense to me but it has worked for other people.

    Roll it around in clear varnish and increase the diameter.
