ELI5: If the barrel of a gun is completely round, why is the kickback after firing always in the up direction?
gpt
The barrel in general is above the hand, when the force is generated by the bullet being accelerated down the barrel the hand is GENERALLY acting like a pivot point, the force pushing the barrel pushes on the grip, the grip is pushing into the hand but the grip had force being applied to one end only and therefore the whole gun tries to pivot up in the hand as there is no force being applied to the other end of the grip there for it pivots.


There is an actual revolver (I would have to find the forgotten weapons video) that was designed to have the barrel inline with the hand not above it for this very reason.
