I just bought the 9MM EZ. Haven’t shot it yet but watched many videos on YouTube. No sign of the stove piping issue with the 9MM as there was with the .380. If you watch the Jerry Miculec video on the 9 EZ, he specifically points out the magazines have an indent on the top back just below the follower to prevent the rounds from moving. He refers to it twice in the short video. I believe that is the fix and S&W realized it which is why the 9MM mag was designed that way. If that is the case they should be either recalling all .380 mags or just send two newly redesigned mags to each owner with proof of purchase.
