MassGuy said:Most guns eject spent rounds with each trigger pull. Depending on the type of weapon, and nearby obstructions, these casings can travel several feet. They can also roll.
This was from last post but didn't get to comment in time (also sorry for not knowing how to quote properly from a different thread ):
I wish to clarify this answer because "most guns" is potentially very misleading to those who do not understand firearms.
This explanation specifically refers to a semi-automatic firearm. While the spent round of a semi-auto can be observed as "ejecting" when "the trigger is pulled", this isn't how a chamber ejection and loading of a new round to shoot again actually works in any gun.
The reason it happens when pulling (and then releasing) the trigger with semi-autos is because the gun has extra components that allow it to do the extra steps for the shooter.
Just like how a car's automatic transmission shifts gears for you rather than requiring you to manually shift them it's the same idea for semi-automatics (vs a non-automatic). The gears are still shifted (or rather have to be shifted) , regardless as to whether the car or the driver does the shifting.
This is why I felt the need to elaborate-- the guns still have to go through the mechanical process of firing, ejecting, and reloading the chamber-- it's just a matter of whether the gun or the user is doing the above steps after the trigger pull to be ready to shoot again.
