咪on 9, hollowpoint is the default round in almost all police forces, even in the US(pls google hollowpoint 9mm) because Full Metal Jacket is deemed underpower and unsafe for law enforcement use. HOLLOWPOINT: In order to maximise stopping power of pistol rounds the projectile is designed to expand in soft tissues, giving it similar wounding performance of a rifle round. It also has weak penetrating power, so it will tumble but not exit the shot body, mitigate the chance of hitting any stranger.
