I have eight of them. I have never had this problem with any of mine. I would send it back to NEF for a checkout. I know they will fix whatever the problem is. Do you hear a good solid click when the latch closes? Make sure there is no metal shavings or maching scrapes anywhere that might be preventing it from closing good and solid. Sometimes they need a very good cleaning as this seem to not be done at the factory. Open and shut it damn good and hard a few times then check it again.
