Known but rare issue w/the KRISS Vector *updated

There are a few stories that are floating about on the web, with failure to feed malfunctions that still have the pin, somehow hitting the primer…I don’t know how but it happens.  Anywho, the round is exploding inside rifle, with the explosion taking the path of least resistance, which is down.  This causes the magazine to fall out of the mag-well, seeming like the operator accidentally hit the mag release button (update: unlike other auto/semi-auto rifles, the bolt is very short in length.   With this, the firing pin is in range of the hammer at an early stage, meaning the hammer can hit the pin before the round is fully in the chamber).

Recently over this past weekend, my rifle has been failing to feed with only about 500 rounds expended through it.  A little fear is starting to brew inside of me; will my rifle explode and injure my hand? will I be next?

KRISS always had a lifetime warranty on these rifles but recently they replaced it with a one year warranty.  From my experience with tactical companies they typically will take care of you on legitimate manufacturing problems (Surefire sent me a new bulb and batteries, 2 thumbs up).

*I called KRISS since my Vector Gen I jams about every 6-7 rounds.  They said to use brand new ammo, not re-manufactured ammo.  The Vector is way too precise (finicky),  that it pretty much cannot except ammo that has even the slightest deformation.  They say that by the end of ’17 they will have new internal parts to send to Vector Gen I owners.  This is probably why Gen II was out, with pretty much the same look.  The Kriss rep told me Gen II has the updated internal parts already installed.  So far Sig Sauer makes ammo (brass) that works perfectly and Fiocchi rounds will work with a little bit of work on the feed ramps (polishing, may need a filing w/polishing).

**Update #2: After speaking with KRISS customer service, certain serial numbers from the early Gen I rifles are eligible for some upgrades, but not for the Gen II internal upgrade.  Also you need to be the original owner to qualify for the FREE upgrades.  As of right now, they do not know what it will cost for owners to get the Gen I upgraded.

***After speaking with KRISS customer service and the Marketing Director.  They do not feel responsible for the Vector Gen I’s issues.  We Gen I owners will have to pay for the upgrades in order to avoid injury and damage to the rifle.

  1. I just got a gen 2 in 9mm and sent it back for exploding cartridges. Got it back today went thought about 50 round with no problem then it started again. Not happy with this gun. Don’t feel safe shooting it.


    1. Sorry just saw this. I’ve had zero issues since my one incident. I no longer use steel ammo, which could have been the issue since they don’t expand and contract like brass
