Take it easy fellas, I think there was just a misunderstanding, no big deal. I think we all agree, when the slide is locked back and new mag inserted, it should stay locked back. Sometimes it doesn't, and one explanation I heard is that slamming the new mag in makes the polymer frame flex just a little bit, but that little bit is enough to release the slide. I don't know if that's true or not, but I found it To be an interesting idea.
