This isn’t a review, it’s a How it Works from the talented 45Snipers YouTube channel. Creatively rendering the internal workings of firearms in a concise manner with a look at each part in the cycle and the job that part does.
These things are probably my favorite types of educational videos, as they show the whole cycle of operations at a speed you can absorb. Firearms are a series of very simple machines carefully built around each other to work in a specific order. Ramps and springs combined with material to safely handle the various pressures and stresses involved.
In that regard, they are very simple. The complexity is in getting all of those machines to work in the proper time. That’s the magic. Each spring doing the job at the right speed and strength, each lever pushing in the correct sequence, and all of it in such a tiny space when it comes to a handgun.
