I reread this trying to understand what the supposed flaw was. If their was a single incident of an accidental discharge and is not repeatable or occuring in more than one 870 at is not a design flaw. I would question the care and cleaning of the individual gun. If the flaw really exists then the curcimstances for it to occur could be recreated and a discharge should occur. I'd like to ask NBC's "Expert" to DEMONSTRATE not just talk about the flaw.
