From what I read there really isn't an advantage in hollow point. Bullet becoming wider has the drawback of lower penetration.

For example if the attacker has his arms in front of his torso, an hollow point might not be able to go through his arm and still hit the torso with enough force left.

EDIT: thank you for correcting me, I was wrong.
