Hornady Critical Duty 9mm 135gr FlexLock - 25 Round Box

The Hornady Critical Duty 9mm 135gr FlexLock delivers barrier-blind performance engineered for law enforcement professionals. This premium defensive ammunition penetrates barriers like auto glass, plywood, and heavy clothing while maintaining consistent expansion and weight retention.

What Makes This Different

The FlexLock bullet features an innovative elastomer insert that prevents hollow point clogging when passing through barriers. Unlike traditional hollow points that can fail to expand after barrier penetration, the FlexLock design maintains terminal performance regardless of what it encounters first. FBI testing protocols validate this ammunition's ability to deliver 12-18 inches of penetration in ballistic gelatin after passing through various intermediate barriers.

Key Features

• FlexLock bullet with elastomer insert prevents hollow point clogging
• 135-grain bullet weight optimized for 9mm Luger defensive applications
• Nickel-plated cases resist corrosion and enhance extraction
• Low-flash propellant reduces muzzle signature in low-light conditions
• Cannelured bullet with InterLock ring ensures consistent expansion
• Meets FBI test protocol requirements for law enforcement ammunition
• Compatible with all 9mm Luger firearms including subcompact pistols

Field testing demonstrates consistent velocities around 1,010 fps from 4-inch barrels with expansion diameters averaging 0.60 inches. The ammunition functions reliably in duty pistols, concealed carry weapons, and patrol carbines. Temperature stability maintains performance from -20°F to 140°F, meeting demanding operational requirements.
