Your video says that the lock would have to be installed incorrectly for the Glock to fire.
The trigger lock post actually goes behind the trigger, not in front of it.
If the bar/post cannot be placed behind the trigger, then the lock does not fit the gun/should not be used on the gun.
For the type that fit inside the trigger guard, like the one in the video, they also have to be installed correctly or they won't work.
Even if installed wrong and loose, such that the trigger could be pulled, the operation would be slow. You would not be firing the gun rapidly.
You can also buy quite a few guns now with a built in keylock in the firing mechanism. You can also buy many pistols that will not fire if the magazine is removed.
Plus, the overall point is that there are low-cost locks that you can buy that work. There are low cost options to secure your firearms from your kids. There are safer choices out there.
Unless you know where the little "button" (is that the right word?) is inside the magazine well like on a Browning Hi-Power.
