You might be wondering about the inner workings of the small parts of your Glock 19. Well, we are here to tell you exactly how a Glock works.

When you pull the trigger on a Glock, the trigger bar will pull the firing pin back. The connector generally guides the trigger bar downward and releases the firing pin.

It allows the firing pin to charge up and hit the back part of the bullet. The gas that expands inside the bullet chamber pushes the bullet out of the barrel at a very high speed.

After the bullet has left the Glock, the slide is pushed back because of the recoil force produced by the bullet. This way, the barrel is unlocked, tilting downwards.

The extractor is then able to remove the cartridge of the spent bullet from the Glock chamber. A new cartridge of a bullet is automatically loaded inside the Glock.
