Ouch! That's not good to hear. I was really leaning toward the Kel Tec .308.
Yes, please do not loose heart in Kel-Tec.
As I have stated in another post, I have had less problems(0) with all of my Kel-Tecs combined than my one R9. And I have fired thousands of rounds downrange with each of them:
(2) 32's
(2)380's
(1) PF9
(1)P11
(1)9mm Carbine
I did not start hearing of Kel-Tec problems until the CCW craze hit and the intro of the 380 and PF9 at the same time.
And like most companies, when production ramps up, QC goes down, unfortunately
