Reactor 5 is the world’s smallest, sleekest green laser sight, created by the laser wizards at Viridian to turn pocket pistols from last-ditch defense to precision-targeting weapons.

Up to 50 times brighter than red lasers for fast, certain acquisition. Seamless fit, pulse/constant versatility, 24/7 visibility. All optimized with Enhanced Combat Readiness (ECR) for instant, fail-safe activation — no fumbling with buttons or adjusting your shooting grip, no hesitation or doubt, more rounds on target. For pocket pistols, it’s the ultimate self-defense upgrade, for reassuring confidence in tense situations.

At the moment of draw, Reactor 5 ignites instantly, automatically deploying the world’s brightest laser, visible day or night, indoors or out, nailing the target with lethal green precision. For decisive impact, nothing else comes close.

The first Reactor 5 models will fit the super popular Ruger LCP and LC9–perfectly integrating into the trigger guard for invisible profile, smooth draw, and improved pistol look, feel and function. A model for the Smith & Wesson Shield will be available soon.

The Viridian Reactor 5 green laser sight is a complete concealed-carry targeting system: pocket- sized Viridian Green laser sight with state-of-charge indicator, custom-fit ECR-enabled pocket holster for secure and subtle carry, and two sets of batteries for familiarization and deployment.
