For some time my carry/class/comp pistol has been a Gen 3 19C.
At a competition a couple weeks ago I noticed that after the first couple stages the accuracy had diminished dramatically. It's always been a solid accurate shooter, and cliche as it sounds, i know it isn't me, because I can pick up my buddy's 17 and drill whatever I'm aiming at. Someone mentioned (elsewhere) that the Compensated Glocks had a tendency to "fall apart" around the 1.5K mark, then tighten back up after another 500 or so rounds. I've never heard of this, but then again, I'm relatively new to the plastic fantastic. (within a couple years anyway.) Thoughts? |
I have never heard of this issue. I'm not to sure how the life of a compensated Glock would only be 1.5K rounds, sounds like whoever said that doesn't know what they are talking about 
I would take some time and the range and really evaluate the accuracy. Then if it is still giving you issues, I would contact Glock and see what they can do for you. |

Never heard of such a thing, or run into it with my one factory comp gun - a G17C. If it's well-used, and a Gen3 should be, by now, then maybe it needs an evaluation and checkup, but I don't see how that could possibly agree with your reported round count of 1500 rounds - maybe I'm misunderstanding?
If it's actually a serious competition gun for you, you should have hit 1.5k in practice the first month you owned it, and been past the 'magic' 2K in another week or two, already, IMO. So my recommendation would be to shoot through to 2K and see where you're at. |

It's the handgun I feel most comfortable with, so it gets used for everything. |

Check that your locking block is not cracked, damaged, or otherwise not normal. Check barrel crown make sure it is not damaged. Does the barrel hood move or loose locked up in the slide?
What is the trigger setup you are running? Stock? Did you try different ammo? What ammo? Did you bench rest the pistol to rule out shooter? |

Looked fine when I tore it down at the competition, crown is good. Everything seems to be just as tight as always. Stock trigger. No to the different ammo, I was running S&B brass in the class. I had benched it prior to the class while chronographing test loads in another pistol. ( was curious to se what it was running) It's not the shooter, as I said, I picked up my buddy's 17 and drilled an 8" plate at 50 yards first hit. |

Not to be an ass but it is almost always shooter unless otherwise mechanical. Nothing against you or anything just stating experience with myself and everyone I have ever shot with. A bullet never lies but you could be shooting inconsistent loads. What were the rounds chrono-ing? Was the velocity drastically different between each shot? I would for sure start with different ammo see if maybe you had bad ammo. |

I was shooting between 1150-1200 when I was benched, but it was still a little "janky" i guess you could say. I attributed it to the rest being slightly unstable, but maybe it is the gun/ammo. I know a local guy who is a certified Glock master armorer/instructor (however that is worded), maybe i'll get ahold of him and let him look at it. An armorers class has always been on the agenda, just never gotten around to it. |

115gr?
Have you tried 124 or 147? My 19 groups better with 147 ammo. I benched mine when I first got it and ran bunch of different stuff through it and the Winchester Train ammo put up the best groups as far as target ammo (silver dollar size groups). Hornady XTP and Winchester Defend did the same (my carry ammo) all of which was 147 standard pressure. 124gr did close or the same as the 147 with only slightly bigger groups (could have been me as well) and 115 was average groups nothing to write home about but not terrible and still within acceptable softball size accuracy. |
