HORNADY - 9MM - 135 GR - FLEXLOCK DUTY - 25 RDS/BOX - RPLH90226

The Hornady FlexLock bullet combines two key technologies: a patented Flex Tip insert that prevents the hollow point cavity from clogging when the bullet passes through barriers like denim, glass, or sheet metal, and a full-length InterLock band that mechanically bonds the jacket to the lead core. This means the bullet expands reliably and retains its weight even after penetrating tough intermediate barriers — a common failure point for conventional hollow-point designs.

Hornady Critical Duty 9mm is loaded to SAAMI +P pressure specifications, which produces higher chamber pressure than standard 9mm ammunition. Most modern full-size and compact 9mm pistols from reputable manufacturers — including Glock, Sig Sauer, Smith & Wesson, and Beretta — are rated for +P use. Always consult your firearm's owner manual to confirm +P compatibility before use. Extended use of +P ammunition may accelerate wear on some pistols, so periodic inspection of springs and components is recommended.

While both lines use Flex Tip technology, Critical Duty is specifically engineered to meet the FBI's rigorous ballistic testing protocol, which requires consistent penetration depth (12–18 inches) through multiple heavy barriers. Critical Duty uses a heavier bullet, a more robust jacket construction, and is loaded to +P pressures to ensure it performs in full-size duty-length barrels. Critical Defense, by contrast, is optimized for shorter-barreled concealed carry pistols and prioritizes reduced recoil and reliable expansion through light barriers like heavy clothing.
