Grand Power P40 goes BOOM!

[ottoman]

Bought a used Grand Power on Gunbroker.  Stop at my friends place on the way back from picking it up at my FFL.  I didnt bring any of my hand loads along as I didnt plan on trying it out... was on my way to work. But my buddy had a box of factory loads... I wont mention the brand, but its well known.  Nickle cased hollow points. So I thought I would run a magazine through it to see how it shot. First shot felt good.. just missed the plastic bottle I was shooting at... second round went BOOM... blew the gun out of my hand, blew the mag out... the safety levers off, the trigger off and the sides of the grip out. Luckily no damage to the shooter. We had to beat the gun apart and retrieved the casing. Not a good day!!! Sure looks like a classic double/overcharge to me.

Damn. Glad no injuries.

I'd be contacting the ammo manufacturer ASAP.

Damn! Glad you are okay. Was this Underwood? In Nickel the only other one I know is Doubletap. If it's Underwood, they might be having issues again. Was this a Lehigh bullet round?

 I think that can be fixed with some new plastic pieces. They seem fairly easy to strip down with a punch and hammer.

I was wondering how these pistols would do in such an event with their near full chamber support. It seems it still found the weakest point and let go there.

Hornady also has nickel in the 175 grain flex tip.  And several other makers advertise nickel/brass as they load what is available.

A gun is fixable/replaceable... glad to hear no hand damge

Ottoman, please follow up on this to see how or if the gun is repaired or replaced...

This is an unusual type K-Boom, seeing that the Grand Power is rotated in and out of battery...
It looks like that was a classic overcharge showing substantial casing damage.  The case head being blown apart and folded back shows it unlocked open the action and then push forward on the case.  The brass flowed under pressure as well as the action left the casing unsupported.  The overpressure is likely to have pushed the primer out, unlocking and opening the action, this left the casing further unsupported to allow more failure of the casing.

Good luck getting the proper repairs or replacement.

  Saw the hollow point part now and realize it isn't a Lehigh bullet. Spill the beans on who the MFG is to be cautious of

I agree please advise on the manufacturer for safety purposes.

What does the barrel and slide look  like? With a bulge like that in case head the chamber either failed from an overcharge or it fired out of battery.

Atomic also uses nickel cases and hollow points.  Just got back from running some through my P40.
