Well, 6 weeks later and my Shield .45 is back from warranty work. All they did was replace the mag followers in both mags and test fired. So, I just happened to have 2 different mags with bad followers and that is why this thing was dropping mags? Really? 6 week wait for THAT? I will take it out and burn 150 rounds through it, but I have zero confidence in the "repair". Maybe they fixed it. I'll report back in a day or three.
