Anyone had this happen? I have a G27. One of my mags has the Pearce +1 finger extention. When I first got it, it was extraordinarily difficult to get ten rounds in it. VERY difficult. I was told it would 'loosen up' Anyway, I noticed this weekend that one side of the floorplate had popped off the flange on the bottom of the mag. I put it back on, and took it to the range. Not very reassuring.
