Trijicon Dual Defense M17/18 Fde

The Trijicon Dual Defense M17/18 FDE is a precision reflex sight designed for the U.S. Military's standard-issue service pistols and professional law enforcement platforms. Built to meet the rigorous optical and durability standards of military procurement, this sight delivers the rapid target acquisition and accuracy that operators demand in high-stakes environments.

The Dual Defense architecture combines multiple aiming solutions in one compact housing, allowing shooters to transition between reticle options without removing the sight from the pistol. This redundancy is mission-critical: if primary illumination fails, backup aiming methods remain available—a feature born from field-tested feedback from operating units worldwide. The FDE (Flat Dark Earth) finish resists corrosion and blends seamlessly with modern tactical equipment.

Professional shooters—from active-duty infantry and law enforcement SWAT teams to civilian defensive pistol competitors—rely on this sight for its predictable point-of-aim and minimal parallax shift. Trijicon's proven battery-free tritium/fiber-optic hybrid technology ensures the sight functions in any lighting condition, from predawn operations to urban low-light scenarios.
