Was wondering, does the guide rod pass outside the slide when it's pulled back? If so, is it pulling hard or sticking? See if the hole, to the front that it passes thurough, has a burr or is out of round. That's the only thing I could think of, looking at the diagram.I bought a new k40 ! Guide rod chewed up first time to range . Sent to kahr . Got it back shot approximately 40 rounds guide rod chewed up again. Is ir me or what? Anybody else have this problem?
daggunit, sorry you are having problems with your k40 I have owned 3 of them myself. 1 stainless and 2 black and still own one black. Have put numerous rounds downrange with no problems with any of them. Please let us know what khar has to say about the problem you are having.
