Escuché todo el vídeo en Español. Bien explicado, pero falta una cosita. Oh, sorry...
I listened to all of the video in Spanish. It is well explained but it is lacking one function. The part that I find missing in the video is a demonstration of trigger reset after cycling.
In the explanation that the poster made the striker is always forward, resting on the striker block until the trigger bar brings it all the way back to cock it and then a release lets it go forward.
The trigger bar is set up to not only do a full double action pull, but also to deactivate the striker block. Second strike capability happens in the same way that a double action pistol would have.
Disassembly does not require pulling the trigger. The striker is already forward and would be again after trigger pull, anyway.
Though there are so many things that are similar to the Glock 17 that he compares it to as he is speaking, the biggest difference would be the striker starts from all the way forward and must be cocked and released by the trigger.
I would be curious to see the trigger reset after cycling.
In the MilMag video reset after cycling seems more like a double action only.
