I got my PM9 for a steal because the previous owner could not get it to feed reliably despite buying multiple magazines & sending it on repeated trips to kahr. All it needed was lakeline followers and about 60 rounds break-in per magazine, loading only 3 at a time. The break-in process bangs up the followers a bit so they're not for show, but they now feed 100% and have for thousands of rounds.
