I have a Kahr PM40 that I have owned for maybe 20 years. Sometimes It used to break the plastic magazine follower on the last round. After replacing 5 or 6 of them, I finally gave up and load my first round in magazine with a dummy snap cap. That way it doesnt slam the empty follower into the feed ramp on the last round. 100% reliable but I give up one live round in the magazine.
