Only time I hear of them breaking is when people are trying to remove them to put on new sights. I rarely ever hear of them just breaking from normal use.

Never broke them, but the front sight is either mashed or abraded on my old Gen2 Glock 17. Instead of being flat on top, it's slightly shorter on the top left that it is on the top right. Hasn't bothered me enough to fix it.
I think the biggest thing is a hard bump (drop) will damage the sight especially if it is the front. Saw this on a G19 range rental. One part of the sight smashed or flat. Still usable but definitely distracting.

Reason: Beat me by a second!
ran my od G19 thru 2 pistol classes. sights got pretty chewed up during one handed manipulation drills from my kydex holster. they are definitely still functional, but marred up pretty good.
I have changed most of my Glock Front sights out to Fiber Optic. My rears are the plastic fully adjustable one's. Yes, I do have a couple of spares in my parts box but have never had to use them. On my CCW G-19 I have a brand new set of Merpro Tritium adjustable which are the first I have seen in years and they are really nice. I do carry gun mounted TLR-1 lights on both G-19's.

I pull the plastic and go metal, but a friend has a Gen 2 G17 that he has had since they came out. He has the stock plastic sights and the rear is chewed up pretty good around the edges (but the notch is still OK) while the front is rounded off a little on the edges. He refuses to change them out. I even ofered a set of the plastic from my 17 and he won't change them. Having shot his gun, they are beaten up, but still useable.
