Evaluations of .380 Auto cartridges intended for personal protection consider factors such as terminal ballistics (penetration and expansion), reliability, recoil, and cost. These assessments often involve testing in ballistic gelatin or other media, alongside analysis of real-world incidents and user experiences. Example criteria might include consistent cycling in various firearms, adequate penetration depth to reach vital organs, and controlled expansion for effective energy transfer.
Choosing effective ammunition for self-defense is paramount. An informed decision, aided by objective analysis, can significantly impact the outcome of a defensive encounter. Understanding the performance characteristics of different .380 Auto loads enables individuals to select a cartridge that balances effectiveness with controllability in their chosen firearm. Historically, the .380 ACP cartridge has gained popularity due to its relatively compact size and manageable recoil, making it suitable for smaller, concealed carry handguns.
