Viridian ECR Instant-On Holster Upgrade Kit for X Series, C Series and Reactor Lasers

The Viridian ECR Instant-On Upgrade Kit is the official holster modification accessory that adds Enhanced Combat Readiness (ECR) automatic activation to any compatible holster, so a Viridian ECR-equipped laser or taclight instantly powers up the moment the firearm is drawn and shuts off when re-holstered.

Designed for use with the Viridian X Series, C Series, and Reactor laser and taclight families, this kit converts a standard holster into an ECR-compatible rig without replacing the holster itself, giving the shooter immediate target illumination and aiming reference on the draw for defensive, duty, or everyday-carry use.

The kit includes everything required for installation: an ECR disc, liquid adhesive, an alcohol prep wipe, a wooden applicator, and sandpaper for surface preparation. The ECR disc is bonded inside the holster at the correct location so the weapon-mounted switch makes contact automatically on draw.

Sold separately for shooters who already own a compatible Viridian laser or taclight and want to add Instant-On activation to their existing holster setup.
