I haven't had a mag drop with any of my six 45 Shields so I guess I was lucky. I did call the factory last week to get a half-dozen new followers and they sent them right out. I called, not chat. After I got the new followers, I realized I could easily modify my old followers with a sharp jewelers file or my Dremel. Just don't remove too much material and your old followers will be just as usable as the newer ones.
