Never got an award for pistol.
I was at MCRD or Pendleton back in ‘08 for an educator workshop. Got to shoot the simulator. It was fun, for the pistol range, one of the Marines asked if I needed a tutorial, told him, “thanks but I got it..” Started shooting, all shots were hitting COM and head shots. Ran 2-3 mags through it and the room got quieter, heads started to turn over, granted, these are teachers so not much to talk about. Got done. Stopped for a second, looked around and the entire room was watching me. A major and a colonel were watching and smiled. 2 young Marines pushed some teachers aside and said, we got this…they shot 1/2 a mag, shot like shit, and moved away from the line. A few people in the room said, “Damn” As I passed the officers, the Major gave me a nod. I don’t shoot competition, I’m sure many can beat me but at the range, I only met 1 other person who could outshoot me with a pistol, he won awards in the Army pistol competition. So I’m no Jerry Miculek by any stretch but I’m also not a slack jawed basement dweller. |

If anyone is wondering what it's like working at a gun store this is a good example of something that happens regularly. Good look on the KKM barrel OP I've been around a ton of them because they're local and everybody seems to love them. I never inspected most of the guns I got too closely because I firmly believe you can always find an issue if you look hard enough. I'm a big fan of shooting stuff before worrying too much.
Hope it all works out. |

If you want to know your Glock's chamber dimensions, you'll have to make a chamber casting with Cerrosafe or some similar product. Brownell's sells it.
Glocks are built more for reliability than match accuracy. I'd be okay with a "loose" chamber if a bear was charging me. Maybe try a Gen5, G20 with the new and improved barrel? |

Only Gen 3 Glocks are allowed in California unless I’m a LEO (which I’m not) I agree on loose chambers and reliability but after shooting great groups with pistols for years, I cannot accept 8” at 12 yards and no group whatso ever. Rounds land high, low, left, right and everything in between. |

When you call or send a letter to tell them that their chamber is cut to the wrong drawing, let them know that you're shooting reloads in it too.
They'll put you at the top of the list for warranty work. You'll be so happy with the way it works out.  |

Measured my glock 20 and it read about the same but that's not the right tool for that.
I can hold a cloverleaf at 10 yards with a rest and Ranger T. You can't shoot, you can't reload, or both, or the chamber isn't the problem. Did you try it off a rest? And of course you are using jacketed rounds not lead? |

Montana bullet works is a casting company, right?
So you are attempting to shoot lead cast bullets out of a Gen. 3 barrel with polygonal barrel? Don’t let Glock know. Let me guess, you have been trying both the cast bullets and JHP Noslers without thoroughly cleaning the bore. |

I’m confused - is your concern that the chamber is loose, or that it’s out of round?
I honestly don’t know if two thou is enough of a difference to be an issue, if the chamber is egged along the axis you measured, or if your caliper is accurate enough to be able to reliably measure a difference that small. |

Quote HistoryOriginally Posted By cschaeff: OP, I'm not going to bag on your shooting skills, I don't think that's the issue. But there is a lot more to accuracy than just the chamber diameter. I think your best bet is to get a match barrel installed. You shoot good enough to get good results with an improved gun. No, his best bet is to try factory ammo, end of story. Then he can possibly claim there's a mechanical issue with the weapons. |

I remember back in a simpler time when the OP would just rage out and cut the gun into several pieces.
Come on OP, this one isn’t even hard, it’s polymer. Get to cutting. |

Quote HistoryOriginally Posted By rabidus: Was going to order cerrosafe but wanted to wait for the KKM barrel. Only Gen 3 Glocks are allowed in California unless I’m a LEO (which I’m not) I agree on loose chambers and reliability but after shooting great groups with pistols for years, I cannot accept 8” at 12 yards and no group whatso ever. Rounds land high, low, left, right and everything in between. Quote HistoryOriginally Posted By rabidus: Originally Posted By curiomatic: If you want to know your Glock's chamber dimensions, you'll have to make a chamber casting with Cerrosafe or some similar product. Brownell's sells it. Glocks are built more for reliability than match accuracy. I'd be okay with a "loose" chamber if a bear was charging me. Maybe try a Gen5, G20 with the new and improved barrel?

Rounds land high, low, left, right and everything in between. You should establish your accuracy baseline with good factory ammo and work from there. When I shot matches with my 1911 where brass retrieval wasn't possible, I used Blazer aluminum case 45 ACP ammo, which worked well in my Colt Series 70. If your Glock doesn't shoot well with three or four brands of factory ammo, call Glock. |

Those measurements are junk not the barrel.
Anyone suggested shooting factory ammo yet? |

Just so you all know, this is what it is like working at a gun shop. I literally hear these types of things every day. The only things this thread is missing is a Navy SEAL/CIA spook.

Quote HistoryOriginally Posted By SimonPhoto: I’m confused - is your concern that the chamber is loose, or that it’s out of round? I honestly don’t know if two thou is enough of a difference to be an issue, if the chamber is egged along the axis you measured, or if your caliper is accurate enough to be able to reliably measure a difference that small. Is the chamber the result of the poor groups? Never had this poor groupings before out of any pistol I shot. That’s why I’m on here. The loose chamber is the only thing I can think of. It could be me. Sure. I don’t think it is. I’m on here for any possible answers to the groupings other than me. This is a gun forum. You post something you think is not right and try to get more answers. Instead it turned into a pissing match that I can’t shoot. Dog pile even. |

Or you could try factory ammo like a bunch have suggested instead of refusing to acknowledge that your ammo is most likely the issue. |

This is the only pistol I’ve shot with crappy, down right terrible groups. The Pythons I’ve never shot. $1600 for chatter dog shit? No thanks. Twice? You gotta be kidding me. Other issues were with cheap Rossi lever guns. They fixed one and made it right. Had issues with CZ 527 in 7.62x39. Two rifles also with fail to fire issues. Read on CZ forums I was not the only one. I think the issue is most people settle with bad guns. They put them away and do t shoot them anymore. They don’t take the time to get them fixed properly or shoot so poorly they can’t tell if it’s them or the gun. Sometimes it’s the gun, sometimes is the person. I’m on here to try to figure out why this Glock had poor groups. Never an issue with any other pistol I’ve had. I always found a node with reloads. |

Quote HistoryOriginally Posted By SuperX925: Montana bullet works is a casting company, right? So you are attempting to shoot lead cast bullets out of a Gen. 3 barrel with polygonal barrel? Don’t let Glock know. Let me guess, you have been trying both the cast bullets and JHP Noslers without thoroughly cleaning the bore. Nope. Not at all. Had my cleaning kit at the range. Hardcast bullets will not lead in polygonial barrels. Permitted the bullet is not too small for the bore. The bullets are 22 BHN. After 4 shots, the barrel had leading. They’re sized to .401”. I need a .402 or .403” cast lead bullet. Buffalo bore say on their webpage their hard cast bullets are safe for Glock guns/barrels. Glock says no. Buffalo Bore says yes. I tried with the OEM barrel. They didn’t work. Will try them again in the KKM barrel. |

Quote HistoryOriginally Posted By Kingdead: You don't measure a bore or hole with calipers if you want really accurate measurements. It has nothing to do with being insufferable.
