Glock 20 SF kBoom an experience I hope never to repeat!

Why on God's green earth do people ignore the manufacturers warning regarding reloaded ammunition..........especially in a Glock?

That empty case looks like it has been scrapped head first down a concrete driveway.

Using that brass case in any 10mm is a disaster waiting to happen.

He could have used that brass in a Star Megastar and gotten away with it.
But then, It's a Star and not a Glock.

I'll be very honest, I have NEVER found full power 10mm ammo to be any kind of pleasant to shoot from a Glock, except for UNpleasant.

Wow. I have shot 1000's of rounds through my Glock 20C with no issues. Including some very hot ammo. 95% of those through a LWD 6" barrel, and the rest through the ported barrel.

I have to say, you all are making me re-think my current plans.

As a current 10mm owner and shooter (DW 1911), I have been looking at the G20SF as a supplement/alternative. The only way I can afford to shoot 10mm is as a hand loader.

I guess I could say that the same is true of any centerfire caliber, but one may pick up spent cases in 9mm/.40/.45 at the range or buy once-fired cases by the thousand very economically.

This is not true of 10mm.

The more I read about Glock's unsupported chamber and the damage that a standard Glock barrel inflicts on that pricey 10mm brass (to say nothing of the polygonal rifling which is not lead-hand load-friendly) the more I am thinking that a G20SF is not a wise choice for me.

That is unfortunate, because I am no different from those who are looking for our next gun, and trying to find a way to rationalize it.

Reality can be a tough mistress.

Ka-bewm!!

If you plan to run a lot of "zippy" 10mm in a Glock buy some insurance - like an after market barrel. Especially if you plan to get more than one or two loadings out of your cases.

glocks maybe a great gun when it comes to reliably but not so much when it comes to strength and there is no way I would run any warm 10mm through it let alone hot ammo. A barrel seems to fix most of there problem but if you plan on reloading and not getting a different barrel I would just recommend getting a different gun.

The SAMMI max pressure between .40S&W and 10mm is about the same as 9mm and 9mm +P

Nobody blows up 9mm pistols with +P ammo. IMHO Glock poor case support is the problem here.

I have to say that I don't think I've ever heard of a Glock Ka-Boom that didn't involve reloaded ammo (at least on Internet boards).

The one downside to Glock is that they don't seem to handle reloads like other guns.

No biggie to me since I'm not (fill in blank) enough to go against the manufacturer's sternly and oft-worded instructions to NOT USE RELOADS.

Well most factory 10mm is very light so hard to say it always happens with handloads. This may have happened with Buffalo Bore, for example.

Its funny how many Glock owners just accept this as SOP.

I wonder how many times that piece of brass had been reloaded?

I think its funny that a reloaded round kabooms a glock, and its automatically the fault of the Glock.

Reload or not, the case webbing looks to be much too thin. From the photo it appears the webbing stops right at the forward section of the rim cutout. Defective brass?

Safety is priority number one.

I'd rather blow up a Glock a month than to have to pull a Ruger trigger once!

Not exactly, though it certainly doesn't help. There are difference between 10mm and 9mm irrespective of the gun firing them. 10mm is a relatively weak case. 40 S&W cases are stronger. 9mm even stronger. 9mm can take some serious pressures.

I suspect the gradual reduction in 10mm data/loads is due to a combination of the crap FC brass combined with the Glock chambers rather than solely being Glock's fault.

I keep seeing these pictures of how Glock improved the chamber support on the 40 S&W pistols, but never a comparison of 10mm. Did Glock also revise the feed ramp on the 10mm guns?

Yeah only real men can pull the trigger on a Ruger.

In their infinite wisdom to beat S&W to the market with a 40S&W Glock, which they did accomplish BTW. However, many of the first gen 22's kaboomed due to the lack of case support.

Glock specifically states no handloading, my friend put a squib thru and there was enough power to rack the slide and chamber a fresh round which he set off and bulged his barrel and locked the gun up on a g23...and i witnessed it all.

Funny how Glocks can fail, and the fanboys always blame everything but the gun.
Broken triggers, frames, faulty extractors, ejectors, recoil spring assemblies, and slide rails.
And the Glock's still "perfection".
Oh, I forgot, those are all "old issues".
Yet, when another brand of gun has had an issue in the past, that's proof that it's garbage and you should just buy a "perfect" Glock instead.
Fanboyism is bad. It leads people to believe Gaston Glock's BS marketing and BS "torture tests".
"We froze the Glock in a block of ice, thawed it out, and it worked." Gee, a gun that's not frozen solid actually works? Amazing.
"We dunked it in mud and then washed all the mud off, and it worked."
Gee, a gun that's not full of mud works? Brilliant.
"We ran over it with a gutted-out, stripped down van, with half the air let out of the tires and it didn't break."
Really? My boss in 1990, ran over his POS Davis .32 with a U-Haul JH. That's the 26 foot, IH diesel truck. Tire pressure was 110 psi cold. It didn't crack the "cheap, pot metal" frame, and the gun worked perfectly afterward. THAT'S a torture test, especially, since Davis' guns weren't known for reliability.

I don't hate or dislike Glocks. They don't fit my hands.
What I hate is Gaston Glock's BS. "It's not PLASTIC, it's POLYMER!!"
He has successfully preyed on the average person's ignorance of the subject of plastics.

It has a "safe action" trigger. It won't fire, unless you pull the trigger. Wow, really? All other guns must have thought triggers.

So as long as you stick with Glock 9mm's you should be fine right?

And you will be fine with other calibers as well. Just use knowledge - standard factory ammo will have no issue in a Glock 10mm.

I'm NOT defending Glock. I'm no Glockfiend - own lots of guns, including some Glocks. They make a gun, in most case satisfactorily, but they certainly are not the best. I do think it's really screwy that Glock doesn't properly design the 10mm barrel to prevent this with even the hottest, weakest brass ammo. Well I guess they have changed the barrel a couple times. I bought a longer barrel because I wanted it, the side effect is I don't have to worry much about unsupported chambers.

I was also under the impression the Colt Delta elite chamber is not fully supported, but better than Glock.

"Evidence suggests this was due to the unsupported portion of a case failing. The gas venting into the frame blew out the magazine and the ambi mag hole cover blew apart. "

Err, gas vents through the barrel, through the frame, and out the ejection port. Look through the side of a Glock, where the frame meets the slide: it's see-through as it is part of the design in being practically self-cleaning.

What blew out the magazine was the explosion through the sidewall of the overused brass casing. I have several aftermarket barrels for my Glocks (No, none of them are LWD) and they are similar in support to Glock's; .40, .45. 9mm. 10mm, and 400 CorBon.

Thousands of rounds down range, and not a single KB-it is NOT SOP.

Glad you were not hurt.
