The Chain of Events

The other day I was thinking about the primer being the most important part of the firing sequence -- but quickly realized it is only one link in the entire chain . . .

Before the primer can explode, it must be struck...

Before it is struck, the hammer must fall...

Before that, the trigger must be pulled...

And before the trigger is pulled, there must be a decision made to fire the gun...  (There better have been a decision made to fire the gun.   If not, that indicates negligence in trigger finger discipline!)

In the end, I wound up with 17 steps in the chain of events that describes the gun-firing sequence ::

  1. A decision is made to fire the gun, which

  2. Moves your finger into the trigger guard, which

  3. Allows your finger to press the trigger, which

  4. Unleashes the energy stored in the hammer or striker spring, which

  5. Propels the hammer down or striker forward, which

  6. Hits the primer, which

  7. Causes it to explode, which

  8. Ignites the powder, which

  9. Burns -- changing it from a solid to a gas.  Lots of gas, which

  10. Generates the pressure that forces the bullet down the barrel, which

  11. Results in the forward momentum of the bullet going toward the target, and which

  12. Pushes the brass rearward, contacting the breech face, which

  13. Results in the rearward momentum and movement of the slide, which

  14. Ejects the spent case and compresses the recoil spring, which

  15. Uncompresses -- moving the slide back to its forward position, which

  16. Loads a new cartridge into the chamber, which

  17. Reloads the gun for the next shot -- for whenever you decide to shoot it.

Or . . . you pull the trigger -- the gun goes BANG.   Either way you want to look at it...
