Christ I hope no one was injured.

Was this your personal firearm????

Wow, I agree with Ducati, I hope no one was hurt.

And the MK23 was tested with a double charge proof load, I think, during the pistol trials. I wonder if the same thing could or would happen to a MK23.

The mag must've launched out of that thing like a rocket. Yikes!

Any metal come off the slide too?

[soopafly]

is this the same USP with the O ring match barrel and Expert trigger from an earlier post?

That's not from a double charge.

That's a reload with a bad case.

When brass fired from unsupported chambers is constantly resized, you'll notice a ring around the case.

If you shoot 40 S&W out of a Glock, USP, or any unsupported bbl you'll notice a telltale bulge in the empty cases. As this is resized time and again it makes the structure of the case weaker.

Sooner or later the case goes at that point and the charge decides that's the path of least resistance and it goes that way instead of down range... then the gun goes bad like this one did.

There's a number of other factors involved...enough that I won't willfully shoot a 40 caliber Glock or USP.

Although I have seen this in 1 45 ACP and 1 9mm incident, the overwhelming majority that I've witnessed has been 40 S&W using a mid to fast burning powder.

That is a .45, so the "myth" of the unsupported chamber does not apply here.

[Mike Searson]

This gun may have had a supported chamber, but so what.

I'm betting the brass that went into it was resized too many times and was fired from guns without a supported chamber.

Catastrophic failure at the ***-end of that case points that out.

interesting....

What would a double charge do?

Not blow out the back of the case?

So you never did tell us, was that your USP?? The one in the pic has the expert trigger -- just as yours does in the other thread!! Same gun!?!?

same gun next weekend

[Turbinator]

Holy cow, what a shame!!

Sorry to hear it - let us know if you are able to get any repairs or replacements from HK, although understandably it is not their fault. Curious what costs are involved.

You weren't hurt, I presume, in the blast?

Was this your reload?

Hk said 130.00 for new frame.
5 weeks to do it.
