I apologize for hurting your feelings!
Cool! Thanks....No.
Your finger is "powering" the cylinder to turn to bring the next round ready to fire on a revolver.
A semi auto, your finger is simply making the pistol fire. But it's the firing of that round that powers the slide back to chamber the next round.
Does a round "load" ready to be fired when pulling the trigger on both, sure. The difference is in HOW those rounds are "loaded" to be fired.
