I taught a CCW class yesterday and allowed a few students to shoot my glock. One shooter shot a mag and handed it back to me. Immediately I noticed that the pin was sucking way out! I pushed it back in and continued to shoot another 100- 150 rounds with out any issues. The shooter was an inexperienced shooter and I was watching her shoot very closely, I didn't see anything out of the ordinary with her grip or anything...just that she wasn't managing the recoil to well.
Any input on this? Thanks! |

Gun was a gen 4 G19. Ammo was PMC. Total rounds fired that day was appx 250 and the incident occurred once about half way through the shooting. This glock has probably close to 800 rounds through it. No problems what so ever so far. |

Yes there are grooves on the trigger pin, but if you break down your Glock on a regular basis the pins will eventually have some travel over time. We started really seeing this years ago with the addition of gun lights. We were told the gun lights redistributed the recoil in the gun just slightly enough to exagerate this issue, but it was not a big deal. To solve this, everytime I break mine down I put a very small dab of clear nail pollish on the outside of the frame at the pin hole on each side. When I get ready to break it down again I just punch right through it. No travel in the pin anymore, and no mess created in the gun by the pollish either. Easy fix to a minor issue.
ETA: I've seen the locking block pins travel too. |
| Should not have to detail strip glocks for routine care- parts replacement only- detail stripping is for the OCD crowd and does little if anything to improve care of the gun. My current 19 has at least 25k through it and was stripped just once for inspection by an armorer. No need to ever do it again unless you break or replace a part. |

I'm going to shoot another few hundred rounds in a week or so. I'll update here if anything happens again. |

I have inspected everything and know what I'm doing this isn't my first glock son. I fully intend to see if it will happen again by shooting it. I don't really care what Glock says....if it happens again I'll order replacement parts and/or sell it. Truthfully I don't think it will happen....I have a suspicious feeling that it happened because of the rookie shooting it.
I'm not dealing with sending it back to glock, which is probably what they would say. |

(ie. the pin itself, the frame, or the spring that holds it) |
| If there's insufficient tension on the slide stop lever, then there won't be enough tension on the trigger pin and it could walk out. Be sure the slide stop lever is working properly and that the spring is under the locking block pin. This problem has nothing to do with who is shooting the gun. |

I have seen trigger pins break on a Glocks before. If it walks out again just make sure your not only pushing half of it back in. If it is broken then just replace the parts. I have snapped two pins, replaced them with titanium pins and have not had the same issue since. |

I have seen locking block pins walk alot more than the trigger pins, and as I stated above we started seeing this with the addition of the old Streamlight/Insight Tech plastic gun lights when they first came out. Since it was associated with minor re-distribution of recoil along the frame it would make since that a weak grip on the gun (female shooter in OP's example) could have contributed to it happening on this gun.
It is not a big deal at all. The likelyhood of it walking all the way out is very rare, and since it is obvious when it happens it's no big deal to push it back in. Remember that Glock's rely on their plastic to metal contacts throughout the gun to eliminate friction (firing pin sleeve/firing pin, spring cups to firing pin channel, etc.). It's not that far fetched to understand that a metal pin is going to move through a plastic hole where the fit tolerances are not that perfect. Easy fix to a minor problem. Keep pushing it back in when it happens, or secure it with a removeable substance. Also, it is not a bad idea to learn how to break your gun all the way down to inspect and/or clean parts. Sticking your head in the sand until a part breaks is like spitting in the face of Murphy. Take an armorer's course, and become more confident with your weapon. Glock does a great job at education on the easist gun in the world to work on. |
