Hard lesson on shooting lead in polygonal rifled barrel

[da gimp]

Glocks blow up even with jacketed & FMJ reloaded ammo, it's not just the lead bullets causing the blow ups...........it is the crude/cheap unsupported case head/chamber that is the problem.......... Buy a BarSto replacement barrel & you can shoot anything you want in a Glock................

There is an interesting section in Wikipedia on polygonal rifling and a comment on Glocks with lead bullets here:

http://en.wikipedia.org/wiki/Polygonal_rifling

It reads: "One suggestion of what the "additional factor involved in Glock's warning" might be is that Glock barrels have a fairly sharp transition between the chamber and the rifling, and this area is prone to lead buildup if lead bullets are used. This buildup may result in failures to fully return to battery, allowing the gun to fire with the case not fully supported by the chamber, leading to a potentially dangerous case failure."

Interesting read. As noted most leading was from in front of chamber about half way down barrel.

I am happy that the young man was not hurt in a physical way and hope he learns from this issue. Glock states not to use lead in their style barrels, what's so hard to understand? Again, I have witnessed this before hundreds of thousands of times, and I never exaggerate! People refuse to read the instruction manual before using a product. I do not understand their thought process and do not understand why they think they are smarter than the people that built the object. They always know better, however it can bite you in the ass as it did with this young man. Also, if he was told by someone who knows not to use lead with that barrel and he shot it anyway, then he is a stupid jackass! People like him are dangerous to others not only to himself. He is a complete idiot! I hope he uses birth control for the sake of the nation!

Glock's instruction manual also says NEVER carry the pistol with a round in the chamber and, along with most other manufacturers, state "do not use reloaded ammunition".

How many people follow the book on those two points?

Lol... later after he blew his up I let him shoot my 1911 a 686 and 64 Smith....He liked the 1911 until I told him I had 1500 in it. He has several guns but it looks like 5 to 600 price range is his limit. I pointed him towards Rock Island but I don't think I converted him.

1 glock 17 kaboomed $500
1 replacement glock 17 $500
1 barrel to shoot lead bullets $110

$1100. He saved a lot of money, didn't he?

I violate rule one at least 40 hours a week. They also say to use a nylon bore brush instead of wire which I find weird.

If you read the material and you comprehend it, then you would know that Glock has a legal statement on how they want their products used. On the issue with "do not use reloaded ammunition", one must understand the liability laws along with what ammo Glock used when testing their product. If I manufactured a firearm, I too would have a "do not use reloaded ammo disclosure"!
Carrying a firearm with a loaded round in the chamber is common and no one is going to change that with any disclosure. I carry a S&W 38 spl. revolver with the exposed hammer in a shoulder holster. The weapon is on my person for protection and is the last resort on an assault
I don't expect to use 6 rounds, but also carry two speed loaders with an extra 12 rounds just in case. Remember, "one who fights and runs away, lives to fight another day"! I watch who is around me and there has been many times I was uncomfortable and removed myself and family from the area before something could happen.
If I carried a semi-auto, it would have one in the pipe!

I USED to shoot lead through my Glock 26, I would clean it after every 50 rounds, that didn't seem to matter one day, it went ka-boom! It didn't break the frame but it did blow out the take down lever and left a nice powder burn across my trigger finger. I sold the pistol after that because I would flinch like crazy with it. Now I have a Glock 22 with a conversion barrel for 9mm with standard rifling.
