Ammunition chambered in .380 ACP (Automatic Colt Pistol) selected for self-protection is typically chosen based on factors such as reliable feeding, sufficient penetration depth, and consistent expansion within a target. The decision process often involves analyzing ballistic data from independent testing and considering the specific firearm in which the ammunition will be used. For example, projectiles exhibiting controlled expansion and meeting or exceeding FBI penetration standards in gelatin testing are often prioritized.
Selecting appropriate ammunition for defensive purposes is critical because the effectiveness of a firearm in a self-defense scenario hinges on the performance of the projectile. Considerations include minimizing the risk of over-penetration, which could endanger bystanders, and maximizing the potential for rapid incapacitation of a threat. Historically, advancements in bullet design, such as hollow-point technology, have significantly improved the terminal ballistics of handgun rounds, including those in .380 ACP.
