the barrel does not spin in a S&W, or any other brand of modern revolver. The part that rotates is called a cylinder, and it is turned by a piece that is called a "hand
", or a "pawl".

The answer has two parts - 1. Why do you want it to spin: It allows the bullet to be more accurate and travel further. The bullet spins for the same reason that football players spin a football when they throw it. 2. Why does it spin (How do you make it spin): Inside the barrel are grooves (rifling) that catch part of the lead of the bullet and spin it like bolt spins when you put it into a nut.
