At the right rear corner where the slide presses down the trigger bar during cycling, I found mine was not being pressed down but instead was getting smashed between the slide rail and the polymer frame rail.

          This caused a great deal more friction and resulted in failure to feed, failure to eject and failure to go fully into battery, not to mention no trigger reset.
          Why does it do that? When the trigger is pulled, the Trigger Bar (TB) slides forward. As it moves forward, it tilts inward toward the frame rail due to the torque applied from the trigger pulling and the cam resisting the pull.

          In the first of three pictures you can see TB at the rear tilted slightly out, 0% trigger pull.

          Second picture; 50% Trigger pull, TB in middle and tilting inward as indicated by the shadow. At this point, the TB is most susceptible getting wedged between the slide rail and the frame rail.

          Third picture; Trigger at 100% pulled all the way back, TB forward and tilted back out away from frame slightly.

          In this picture you can even tell the top portion of the tab has been ground away and is thinner at the top.

          Here the slide rail has been worn uneven and is thinner at the end of the rail. Compare the two rail ends on the right and left. The rounded corner I did as part of the fix. But the width of the two is different.

          The fix? I removed the side panel and grabbed the top of the trigger bar with pliers. I pried the top most tab of the trigger bar outwards, away from the frame rail. I had to reassemble, test and repeat several times before it was moved out away from the polymer rails and properly pushed down into the frame by the passing slide.

          Suddenly the slide racks so much smoother and easier without binding up like before.

          Just found and watched your YouTube video on shooting 27 rounds through the Kahr P45 which led me to this post. I think you're onto to something regarding the top of the trigger bar get stuck between the frame and the slide rail instead of contacting underneath the rail. I am a total novice but when I disassembled my CM9 I noticed that the curved part on the top of my trigger bar had also been worn thin. Now it seems to slide pretty easily between the frame and the slide rail although I doubt it was designed to do so. I bet that is part of the reason Kahr advises a 200 round break-in period...in order to wear thin the trigger bar.
          Anyway, I admire your tenacity to find the root out the cause of your P45's hangups. Not many people would have noticed this. In fact, I am surprised this has not gotten attention on this forum, many even its own sticky on the break-in thread.
          Well, thank you for bringing this to my attention and I will certainly check the trigger bar on any new Kahrs that I buy in the future.
          Best of luck and happy shooting!
