I didn't make a video tonight, but I did drop my Glock with Skimmer ~3' onto my garage floor, making sure it landed frame-first.
The trigger bar did drop from the force of the impact, releasing the striker. I repeated the experiment with the same results.
So now you'd just be counting on the firing pin safety to do its job. Releasing the striker via an armorer tool through the rear armorer cover plate while a pencil rests against the breechface does not launch the pencil.
