Kel Tec Sub2k WWB Issue

[NuclearSociety]

Well I tried out my sub 2k the other day at the range, also brought my PF9
And well below is what it did to some Winchester white box (WWB) ammo.
It kept having FTE (Failure To Extract) malfunctions.

It would slam the slide on an empty casing and try load one at the same time.
The Federal 9mm I used worked perfect but the WWB had all the problems.





ALSO just noticed these small cracks, are everyone sub2k's like this or did the shell casings do this?

Wow,I know some ammo brands work better in the same gun but that's a really big issue. Any idea why ?

I had the same problem, first time out.

I sent mine back to Kel-Tec and they made necessary repairs.

About a 3 week turnound.

Not a clue, thats what I am trying to find out. The Federal 9mm 115gr FMJ works flawlessly in it though.

I am going to get a glock 17, 17 round magazine and see if that helps. I am using a glock 10 round that came with it atm.

What was the problem that caused it to have the issue?

Mine is doing this as well . shoots federal and remington just fine but remington whitebox and cheap liberty ammon just dont extract .

kel-tec told me to ship it to them in a box marked machine parts does this sound normal

Well a firearm is a mechanical tool...

But did they say what they would do to it? Would they charge you for it? Etc.

I've only had problems with Blazer steel cased ammo on my Sub. Apparently, its a HUGE no-no to use steel cased ammo in a sub2k.

Mine eats WWB like nothing.

hmmm...
Well the federal 9mm is only like $1.00-$2.00 more if I buy that instead of WWB.
As the WWB is like 21 something for 100 rounds and 2 boxes of 50 of federal is like 22.30

BUT I do only have good things to say about my sub 2000. Its accurate as hell! Right where I had the sight is exactly where the hole went .

Ah, I know that squared keyhole blown in the case.


The round is not seating all the way in the chamber. and the pressure is blowing the cases out.
