The most common breakage we had with them was the striker collett. They cycled but but wouldn't fire unless the slide was racked again, so you lost half your ammo but could single fire rounds. If the trigger return spring broke they were dead.
While on gun breakages, I've had 1911 slide release levers move a little laterally (like you're trying to remove them) and lock the guns up tight.
Interestingly the firing pin on my old 92 broke and I didn't notice it until cleaning. Still went bang every time.
