Hornady Critical Defense vs. Critical Duty

Hornady Critical Defense vs Critical Duty: What’s the Difference? In this Brownells Tech Tip, we break down the key differences between Hornady Critical Defense and Critical Duty ammunition. While both are designed for personal protection, they are optimized for different barrel lengths and use cases. Understanding how bullet weight, jacket construction, and performance through barriers affect real-world performance will help you choose the right defensive ammo for your firearm. If you carry a compact or micro handgun like a SIG P365 or Glock 43, Critical Defense may be the better option. For full-size or duty pistols, especially where barrier penetration is a concern, Critical Duty is engineered for that role. We cover recoil differences, expansion characteristics, and why matching your ammo to your firearm matters.
