For those of you with failure to feed on the keltec I suggest this.... take it allllll apart and finish it like a more expensive gun. Take out the dremel and metal polish and make that puppy shine. I have put a mirror polish job on my feed ramp and it eats just about everything I have thrown at it. Polishing the outside of the chamber and the ramps where the barrel tips up took a lot out of the effort to rack the slide and makes that puppy sing. I also took the hard bristle brush attachments and used it to smooth off the rough plastic mold marks.
It is not going to turn your keltec into a glock, but it will cut down a lot of common issues.
Is the ruger trigger a smooth pull or does it get harder as it goes back like the keltec?
