Kabooming Vectors are absolutely nothing new. You didn't cause this, they regularly do it with factory ammo. My 9mm Vector blew up on Factory Federal HSTs. Just normal plinking. Wasn't bump firing, wasn't even rapid firing. Personally, I think their design isn't quite ready for prime time. I RMA'd mine, and they rebuilt it without complaint. I told them it fired out of battery, they said ok, we'll repair it. When mine went, I was glad I had a foregrip on it....or I would have lost some fingers. I sold mine after it was repaired, and it's on the list of things I'll never own again.
Edit: After looking at your pics....yours was clearly an OOB fairlure, the same as mine. Sure, if your brass wasn't plunking, it could have failed to fully seat in the chamber...but that does NOT excuse the gun design. Yours also was not even close to as dramatic as mine. When mine went, the bolt blew apart, the magazine blew apart, and the mag spring went through my boot. I also had pieces of polymer embedded in arm. Kriss has known their guns have a problem for at least a decade and continue to sell them without any warning. If you google "my Kriss Vector blew up" or "My vector fired out of battery" you'll find hundreds and hundreds of posts. There are basically two kinds of Vector owners: Those who's guns kaboomed, and those who's guns haven't kaboomed yet. The root cause is that they cannot tolerate any ammunition problem, or feed problem. If anything causes that round not feed completely, the gun will fire out of battery every time. Basically every Vector out there is a grenade waiting for that inevitable bad round, whether factory or reload...if you shoot it enough, it will eventually happen.

Thanks for the warning as I know now to never stand next to someone shooting a Kabooming Vector!!!
