Overview
Built for personal protection in a full-size handgun, this 40 S&W load is aimed at shooters who want a defensive round suited to low-light and barrier-focused use. The nickel-plated casing is intended to make chamber checks easier when visibility is limited, while the low-flash propellant is designed to help preserve night vision. Its FlexLock bullet is presented as part of Hornady’s Critical Duty line for controlled expansion and consistent performance in self-defense applications. Packaged 20 rounds per box, it is a practical option for those prioritizing a defensive load with clearly defined use cases.

Considerations & Trade-offs
- Designed for a full-size handgun, so it may not be the most practical choice for compact carry setups.
- Packaged as 20 rounds per box, which is a relatively small quantity for range use or extended practice.
- Built around barrier penetration and controlled expansion, so it is purpose-specific rather than a general-purpose target load.
- Nickel-plated casing can aid chamber checks in reduced light, but that feature is more situational than universally necessary.
