Deep Dive

Overview

The Hornady Critical Duty 10mm Auto Ammunition is purpose-built for high-pressure situations typical in law enforcement and tactical operations. Its design and ballistic properties make it ideal for penetrating barriers such as car doors and windshields without losing structural integrity or performance. This ammunition is especially suited for modern semi-automatic pistols used by law enforcement, guaranteeing consistent and predictable performance in critical moments.

History and Development

Hornady gained attention in the ammunition industry for pioneering precision and quality. The development of the Critical Duty line was a response to demands from law enforcement for ammunition that offers superior barrier penetration with minimal deflection, critical for real-world situations where shots may not always be straightforward. Leveraging decades of experience, Hornady introduced the FlexLock bullet to meet such specific needs, setting a new standard in tactical ammunition.

    FlexLock technology integrates a unique polymer tip within a heavy-duty jacket, ensuring weight retention and robust performance.
  • Is this ammo suitable for all 10mm Auto firearms?

  • Can civilians purchase this ammunition?

Response:David, we do not have specific dates when products will be arriving. These are unprecedented times within the ammo industry. On a daily basis, we are still receiving shipments of all types of ammo calibers, however, not nearly enough to fill the demand. You may want to sign up for notifications for when any ammo in this caliber comes back into stock and try a different brand. To sign up for notifications go to My Account > Communication Tab & scroll down to Notify by Caliber. Please note - Prime Members get this alert 3 hours prior to standard customers as a benefit of their paid membership, so we might not have any inventory remaining after the Prime customers get ahold of it.
