crfish:
I've read through this thread, but I do not think I saw any reference to what you might have found during the cleaning of your R9 between sessions. My off-the-cuff impression would therefore be that your pistol might just need a detailed strip, clean, and lube to remove what I call "break-in dreck" -- shards of brass, aluminum, powder residue, etc., which can build up as the various parts of a 13-ounce locked-breech DAO pistol chambered for a full 9mm Parabellum cartridge and with tolerances as tight as those of the R9 "get to know each other." If you have been performing such detailed clean and lubes between range sessions, I apologize for even bringing up the subject.
The NAA Guardian pistols have been mentioned above in connection with last-round FTEs. As most will know, the Guardians are straight blowback DAO pistols with extractors but not ejectors. They are built like tanks (I own Guardians in .32 ACP and .380 ACP), and their occasional last round stovepipes are, as above noted, considered as a "feature" indicating the need to insert a new magazine and rack the slide.
These R9s are masterpieces. Mine has been my EDC for nearly six years now and has never malfunctioned. (Of course, I treat it like royalty -- cleaning it after every range session and even every week or so even if it has not been fired, changing springs every 200 rounds or so, alternating magazines when I change the clocks, and otherwise treating it as my last line of defense in an increasingly uncertain world.
Good luck in resolving your problem. I'm confident that the factory will make things right if your R9 does indeed have some inherent vice.
