Never shot a Glock have ya?
3 rules of Glock safety:
1. keep your finger off the trigger
2. keep your f'in finger off the trigger
3. keep your f'in finger off the f'in trigger
If you can't remember to keep your finger off the trigger until you are ready to shoot at a designated target, the trigger is not the problem - the safety between your ears is failure-prone.
I love the Glock design; it is simple, elegant, and effective. That being said, I would be extra careful with kids in the house...YMMV ;)
I have heard anecdotal evidence of someone grabbing for a falling Glock and catching it by the trigger - but again that shows a basic unfamiliarity with the design as the drop safety is highly effective.
