Suppressors This is pretty impressive. (Glock Torture Test)

[Tuvai]

Hey guys, I'm a long time lurker but first time poster. I found this and thought it was pretty impressive. Figured if anyone is on the fence about buying a Glock they might want to read this to help them out.

Re: This is pretty impressive. (Glock Torture Test)

They (the good brands) have all been through torture tests, many more severe than the one posted. My favorite is one of the tests that HK puts the USP through. They lodge an oversize bullet inside the barrel, then clear it by firing a round of the correct caliber. Then the same weapon must fire 5,000 rounds without a stoppage. Sig is also notorious for brutal testing. During one test, I saw a P226 get thrown out of a helicopter at 200 ft. onto asphalt only to be drug behind a truck for a few miles down a dirt/gravel road. It was then taken to the range(without a cleaning), and shot a full day of factory accurate groups without a FTF/FTE.

I personally hate Glocks with an absolute passion, but they are tough as nails.

Re: This is pretty impressive. (Glock Torture Test)

I have a lot of faith in the 9mm Glocks. I wouldn't want to own one in .45. It seems most of the glocks that had issues with rounds bursting in the region of the unsupported case were larger caliber Glocks. The polymer frame comes apart when that happens.

I think that was Steve from ADCO that did the test if I'm not mistaken. It was an impressive test.

You might be confusing that 226 with this glock 21 test- the gun is dropped 200feet onto a dirt field and dragged behind a vehicle.

Re: This is pretty impressive. (Glock Torture Test)

Johnny Knoxville's "Jackass" movies are impressive, too, but they're hardly a fair representation of the service life of a human being. Chuck Taylor carefully documented the first 100,000 rounds through a minimally-maintained G17, and wrote occasionally of it thereafter, even noting its first (non-magazine) mechanical malfunction just shy of 200,000 rounds fired. IMHO, that was a much more realistic representation of what the firearms consumer can expect from his Glock than submerging it for a month in a cauldron of simmering pork and beans. Rather than match Mr. Taylor's investment of time and ammunition, now the blog-and-magazine report crowd resorts to much more covenient sideshow antics and make believe it has the same real-world relevance.

So where does the fact that a 9mm Parabellum has a 60% higher chamber pressure than a .45 ACP fit into this little theory of yours?

Glock torture tests... wasn't that beat to death in the 90's?

Unfortunately torture tests and reliability tests don't equate!

Less chamber support.

Re: This is pretty impressive. (Glock Torture Test)

I've seen the pics of the unsupported .40 S&W glock chambers (the ones I thought were most notrious for kB) and thought they were bad. Those .45 chambers look ridiculous.

Re: This is pretty impressive. (Glock Torture Test)

Don't a lot of the aftermarket barrels have more chamber support? I know LWD barrels do.

That looks like a real weak spot in the chamber right at the 5:00 position

All the "quality" aftermarket barrels do, but at the risk of some feed reliability.

If unsupported chamber were the whole story, it would never happen to 9mms, but it does:

The so-called Glock <span style="font-weight: bold">kB!</span> "problem" is almost entirely traceable to handloads or improperly loaded factory ammunition. One of the keys to a Glock's reliable feeding is loose chamber tolerances, which is directly related to the area of unsupported case. If you think Glock is the only manufacturer to use this technique, I'd suggest you need to check out a GI 1911 (probably the most <span style="font-weight: bold">kB!</span>-prone pistol ever made).

Any autoloading pistol can experience a <span style="font-weight: bold">kB!</span>. The reason it's more closely associated with Glocks is because there are far more Glocks sold (and in use) than any other brand. Sixty percent of all US LEOs are issued a Glock sidearm. It's also statistically significant that since the FBI's infamous 1986 Miami shoot-out, more Glocks have been sold in .40 S&W than any other caliber. Why is that significant? Because there are more <span style="font-weight: bold">kB!</span>s reported in .40 S&W than any other caliber, including .45 ACP.

Re: This is pretty impressive. (Glock Torture Test)

I have a custom barrel in my glock and haven't had any reliablity problems. I think it's more about the design of the gun then the barrel.

Re: This is pretty impressive. (Glock Torture Test)

I am more of an HK guy, having had more experience with them and have had rock solid reliability, that said I wouldn't hesitate to carry a Glock if I liked their ergos as well. The whole kB thing with Glocks is real but overblown I think, and is proof positive of the engineering mantra that you can't get something for nothing. The reliability in part is due to the looser chamber, the loose chamber is harder on brass, etc. etc. Every manufacturer has had kBs as well. Seems like the 9mm Glocks have better records, but I haven't seen any good stats to back that up, and of course reliability across the board has been excellent anyway.

If this Glock really has 150k rounds down it, it is pretty loose by now and will handle dirt better than when new.

I think the test is interesting and fun but not very meaningful as a test of a carry weapon. In a defensive weapon I am more concerned with Mean Time Between Failures in the condition I am expecting to use it in most. This guy says he doesn't care about how many times it fires without failures, just what kind of abuse it can take and still function at all. In a carry weapon my philosophy would be just the opposite - I want the confidence that it will go bang with the first trigger pull everytime after clearing the holster with no failures at all. I understand that is not what he was testing here.

All my carry weapons, regardless of type, have to do at least 500 rounds in a row no cleaning, with no malfunctions of any kind, with at least 200 of that with the intended carry ammo. Just my personal protocol-admittedly arbitrary. I have three HKs that have never choked with any kind of ammo for any reason ever, and thats thousands of rounds in total, 3 perfect records for out of the box production weapons. I'm sure plenty of Glock owners have experienced similar. It's why I had to leave behind my 1911s, though I still lust for them.

With that being said, I guess if you don't mind clearing malfunctions, hide your guns in the wife's flowerbed, and occasionally accidentally bake one in a cake, then maybe you should buy this guy's Glock!

Hope he doesn't loose any fingers when that thing decides it has had enough...

I would expect the .357 SIG-chambered Glocks to have the same problem, but they are a very small percentage of the total number of Glocks in use by law enforcement.....I have personally witnessed two Glock .40s KB during firearms qualification, both while using duty ammo from the same defective lot by one of the Big Three ammo companies. Both of them suffered complete head separations, one (G22) had the magazine blown out of the gun and the extractor blown completely off of the slide. The other (G27) had the slide jammed about half way back, but no other damage. Glock fixed both guns free of charge, event though it was an ammo problem. I have no experience with the .45 Glocks, but I have never seen a KB with a 9mm Glock. I noticed in your photos that the case head did not completely separate, so perhaps the better case head support did help somewhat.....

Re: This is pretty impressive. (Glock Torture Test)

Lifted that pic from another site. m4carbine.net if I remember correctly.

I don't want anything to do with a gun without a proper chamber (full case support). I know that the kBs in question are due to poor ammo, but what if the chamber offered full case support? I'll bet many would not have kB'd in that case. Why trust that every single round of ammo you fire is 100% when this is simply not possible?
