Kel Tec Sub2K .40 Kaboom!

Post by cHaMeLeoN352 » 21 Jun 2012, 15:14

I had an interesting day at the range today...

I was shooting my new sub2k chambered in .40, which has less than 400 rounds through her.

After successfully firing 10 rounds through a 22-round Glock magazine, I handed the carbine over to my friend who fired one-round, which then violently exploded!

Thankfully, no one was hurt, despite a small scratch from plastic shrapnel, but it was scary nonetheless.

I will say that I was shooting my Beretta 92FS at the same time, with 9mm luger and .40 sitting out, so it is possible that a round sneaked in (worst case scenario), but I still don't think it would explain the extent of the damage.

Here are some pictures showing the aftermath; maybe someone can share some input on how and why this catastrophic failure occurred:

You can see the damage was centered at the chamber, with no other damage to the receiver or bolt carrier.

I am going to send her in for warranty repair and hope they can rectify this disaster and instill some sense of confidence in their weapon systems again.

Are you certain the last round made it out of the barrel before you handed it to your friend? It looks kinda like a squib & the 2nd round caused the rupture.


Sucks to lose a rifle but glad no one was hurt

x2. looks like the whole round is in there.

How can you tell it's a 9mm?

Yes, there is a bullet stuck in the barrel (jacket and all), but I would have thought a 9mm would not have gotten stuck like that... where is the .40 that caused the KB...?

No, I was not sure the chamber was clear before I handed it to my friend, as I did not check down the barrel, but as my friend chambered a round he did not notice anything out of the ordinary.

In the end, accidents do happen and to anyone who thinks otherwise, they will be sorely disappointed. Always make sure to keep ammunition separate when shooting different caliber firearms...

That looks like what would happen if a live 9mm was in the barrel and a 40 was chambered and fired. The 40 projectile exploded the 9mm which was in the barrel, and left the 40 projectile in the barrel. Just what it looks like.

Deleted comment,

apparently I missed something but don't know what and too sun-burnt-out to read carefully.

So, just deleted :lmao:

I scanned it, haha.

Did I miss something, I thought he was shooting a .40, and if a 9mm got into there and somehow got fired, I don't see how it would squib.

I had a friend, normally a pretty safe shooter, who was trying to teach/impress a girl out at the range one time. He was using my H&K .40 USP & loaded it with 9mm. It chambered & fired but wouldn't eject the shell. He finally got it out & was about to continue when I noticed the shell looked strange. I told him to wait, checked the shell & tore him a new one. The barrel was clear & undamaged.

So yes, .40s can fire 9mm rounds without getting stuck. Is that always the case? I wouldn't bet on it. Especially since the barrel on a pistol is relatively short but the OP was using a rifle, longer distance for something to go wrong in.
If the 9mm were to start tumbling in the barrel I could see it getting lodged (I do not know the likelihood of such a thing). Follow it with another round, be it 9mm or .40, & it may rupture.

Wackamole wrote:I think the entire case of the 9mm round probably slipped out from under the extractor upon chambering, and when the friend charged a new round in there, the force of the bolt slamming home forced the 9mm round past the chamber and into the barrel. Once the new round was fired, well, there's something in the way, and SOMETHING has to go- in this case, it was the barrel.

At least, that's my theory.
That is what I was thinking as well.

Many years ago I was blasting away with 2 guns. A 1911 45acp and the 1911 based Delta Elite 10mm. Some how I loaded a 10mm into the 45 mag. It shot and cycled without issue. It did of course sound real funny so I stopped and inspected. The side of the 10mm case split but other then that no other damage. Both 1911's where blued and both where using Wilson 8 round mag. So both platforms where virtually identical.

That was the last time I ever shot same platform different caliber guns at the same time.

Wow, six bullets before it broke out - impressive.
