What type of bullet is preferred for police service due to its expansion on impact?

The hollow point bullet is preferred for police service primarily due to its design, which allows for controlled expansion upon impact with a target. When a hollow point bullet strikes a target, the hollow cavity in the tip causes the bullet to expand as it penetrates. This expansion increases the diameter of the bullet, resulting in a larger wound channel, which can enhance stopping power and effectiveness in neutralizing a threat.

Moreover, because hollow point bullets expand, they are less likely to over-penetrate, which not only minimizes the risk of collateral damage to bystanders but also increases the likelihood of the projectile to impart maximum energy into the intended target. This characteristic makes hollow points particularly suitable in law enforcement scenarios where rapid incapacitation is critical, and the risk of hitting unintended targets must be minimized.

The other types of bullets, such as full metal jacket, tracer, and armor-piercing, serve different purposes. Full metal jacket bullets do not expand and are designed for deeper penetration, which can pose more risks in urban environments. Tracer bullets are used to allow shooters to see the trajectory and adjust their aim, while armor-piercing rounds are designed to penetrate bullet-resistant materials, making them less suitable for typical police scenarios where maximizing safety and effectiveness in a civilian
