Viridian HS1 Red Laser FDE w/ Picatinny Adapter

The Viridian HS1 Red Laser FDE with Picatinny Adapter is a compact pistol-mounted targeting system engineered for law enforcement, military, and civilian defensive shooters who demand rapid target acquisition in low-light and high-stress scenarios. Built to coexist with iron sights and optics, this red laser sight eliminates sight picture alignment delays and significantly improves accuracy under pressure—particularly in close-quarters combat, vehicle-based engagement, and night operations where traditional aiming becomes unreliable. The Flat Dark Earth (FDE) finish ensures the unit blends seamlessly with modern tactical platforms while maintaining visibility in varied lighting conditions.

The HS1 employs Viridian's proven red laser technology, generating a bright, precise aiming point visible at extended range without the refraction issues sometimes encountered with green laser designs in bright daylight. At just 0.22 lbs, the integrated unit adds negligible weight to your firearm, minimizing muzzle rise and handler fatigue during extended carry or qualification cycles. The included Picatinny adapter mounts directly to standard MIL-STD-1913 rail systems, allowing tool-free installation on pistols, carbines, and duty rifles with compatible accessory slots. The compact 3.75 x 1.5 x 5.3-inch profile resists snagging on clothing and holsters while maintaining sight radius consistency for co-witnessed setups.

Operators transitioning from traditional sights to laser-assisted aiming will experience measurable improvement in target engagement speed and shot grouping, particularly during movement and one-handed shooting drills. Law enforcement agencies, security professionals, and armed citizens benefit from the HS1's ability to reduce target fixation and improve situational awareness—your eyes remain on the threat while the laser confirms point of aim. Installation is straightforward on any Picatinny-equipped slide, frame rail, or handguard; verification of zero is essential before duty carry or defensive deployment to ensure alignment with your zero distance and ammunition selection.
