Glock 20 big Kaboom

I recently experienced my Glock 20 KB after sucessfully firing four full magazines of both factory PMC loads and custom loads from my shop. When it happened the magazine shot straight out, the Wolff recoil spriing and one pice guide rod launched 20 feet, along with some of the polymer frame. The fram was cracked almost in half and the new Storm Lake barrel was split the entire length on the underside. The barrel tried to blow as the front of the slide was bowed.

My hand felt this sharp pain, especially in my trigger finger, which turned black, and hurt like heck. My right hand went numb briefly, but after two weeks there appears to be no physical lasting damage.

I have sent the Glock 20 back to Davidsons who is forwarding on to Glock. My sales rep at Davidsons said he had never seen anything like it and wondered how I kept from being injured.

I talked with a Glock representative at the 2008 Shot Show, who sounded positive that Glock would probably replace it.

I see from your post that they did even with an aftermarket barrel. Thanks for the encouragment.

My personal believe is that shortening a case that works well (10mm) and using the same bullet weights dramatically decrease the margin for error when reloading. Also, just don't have any place in my "arsenal" for .40. I'm pretty happy with 9mm and .45ACP. I've done a lot of experimenting with .400 Cor-Bon and .40 Super, without having to change platforms.

To reiterate: If Glock's design were flawed in such a manner as to cause KB's, then we'd be hearing of tens of thousands of KB's, not the few that are posted on this and other websites. Ol' Occam even works with Glocks.

duck: Thanks to Glock's design, I suffered no damage from my REAL KB. Felt like I'd hit my trigger finger with a hammer, and I was afraid to look at my hand, as I expected to see part of my finger missing. Looked at finger and it was black, then I was afraid to clean the "black" off, for fear of seeing bone, mangled flesh, etc. Didn't even have a bruise!

As I've posted in the past, I was pleasantly surprised that Glock/Smyrna took care of me, even though I was using an aftermarket barrel with reloaded ammo.

Thanks for the interest and opinions expressed in this thread. I'd bet Ol' Pepper against a DemocRAT's brain (something valuable v. something worthless) that a "certain" specious website only quotes GT'ers who are on my infamous Ignore List, when discussing KB's and GT. That rates a big ol' "hardehardeharharhar!"

If G21's had "design flaws", wouldn't you think that I'd have had a problem by now, having fired over 100,000 rounds of my reloads through my G21's?? Some folks, of course, are offended by rational thought and "critical thinking skills."
