I am in the same situation. I have a 21SF Ambi with Glock rail that has only about 100 rounds through it. I read somewhere that ejecting fully loaded mags can cause the mag release to fail. I did this about 50 times with a 13 round mag and another dozen or so times with a Korean 27 round mag and no failure. I think I will call Glock and see what they say. Also, my gun has factory night sights. Can I assume that a replacement would come with new night sights. That would be nice since this gun is almost 5 years old.
