Fluff and Buff
Yup, hang on tight.
My Kel-Tec needed a fluff and buff, Google it up, it is a "thing"
Pretty sure the issue with the P 11 I bought was the feed ramp. A couple hours doing a fluff and buff made a jam o matic in to a 100% reliable pistol.
I used a rubber polishing point in my trusty Dremel for the feed ramp. I was done when it looked like the surface was glass.
Kel-Tec is awesome, I don't mind finishing up what the factory did not do when the price paid reflects the need for some finish work.
Do the fluff and buff, it's not difficult. Grip that little pistol like you mean it.
