I bought an M&P 380 Shield EZ and a box of Maxx-Tech to go with it. Every single magazine had a FTF. I was kicking myself thinking I bought a POS that would have to go back for repairs and might never run right.
So, in an attempt to find a cartridge that gun would like I went and bought $200 worth of every different kind of 380 Auto I could find. Hundreds of rounds later and not a single hiccup among any of them. Finally tried the rest of the Maxx-Tech box, and got a FTF at least once every magazine.
Maybe their 9mm is ok. I think I've bought Maxx-Tech in 9mm and don't recall having trouble with it. At that price I'd buy more. Just not in 380 Auto.
