Viridian

Specializing in green laser products, Viridian is a local Minnesota based company located just north of lake Minnetonka. Green lasers are optimal for target aquisition and sighting in daylight. They also introduced the ECR (Enhanced Combat Readiness™) holster design which uses magnets to activate the laser on drawing, and deactivate on holstering, resulting in an error proof laser sight with maximum battery life.
