Yes. NJ has restrictions on carrying hollow point ammunition, Arizona does not. It was brought up by a prosecutor in a murder trial in AZ. A retired school teacher shot a person that was attacking him- the prosecutor attempted to portray his choice of firearm and ammunition as "planning" to kill his attacker. That case is being appealed.
As I understand it, only law enforcment personnel are authorized to carry weapons loaded with hollow point ammunition. The same for New Jersey and probably other states. I know of no law that says you can't buy or have hollow point bullets as a non enforcement person. But, as said, non lawenforcement personnel cannot carry a weapon loaded with hollow point bullets. Gun stores sell hollow point ammo. Therefore, you can buy hollow point ammo to shoot on a range. If hollow point ammo was illegal gun stores could not sell it....... Hollow point ammo is illegal only in New Jersey, and even then, only illegal for certain applications (mainly, weapons carried outside your home). Hollow point ammo is legal in all other states.
Yes, you can find a wide variety of readily available 9mm hollow point bullets and ammunition.

Hollow points have a hollowed-out tip that expands upon impact, creating larger wound channels and reducing the risk of over-penetration. Ball point bullets have a solid tip and are designed for reliable penetration and stability, making them better for shooting through barriers or hard targets. Hollow points are often used for self-defense, while ball points are commonly used for target shooting or hunting.
