Why is the recoil less if a person holds a gun tightly against the shoulder?

A. The recoil is not less. Since momentum is conserved, the recoil is the same whether or not the gun is held tightly
B. Your mass becomes part of the system, and since momentum is conserved, the velocity of the gun/person system is reduced
C. If the gun is held tightly the bullet doesn’t travel as fast so conservation of momentum leads to a smaller recoil velocity of the gun.


B. Your mass becomes part of the system, and since momentum is conserved, the velocity of the gun/person system is reduced
