The Glock magazine was initially not drop free, if you remember. As a military pistol, they did not want magazines inadvertently or accidentally falling out during use. The metal inserts were added later, after a winning campaign directed at the American law enforcement market.
I sometimes wonder why I don’t still own a Glock. My move to HK has been great, and I am very happy with them. I do think they are the better pistol.
That said, if you handed me a Glock, I wouldn’t feel like I would be losing much of anything. It would be like old-home-week, as the saying goes.
