Viridian E Series Green Laser for Ruger-57 – Instant-On Activation

The Viridian E Series Green Laser delivers a highly visible 532nm green aiming point designed specifically for the Ruger-57 pistol. Viridian's INSTANT-ON technology activates the laser automatically when drawing from compatible holsters, providing immediate target acquisition without fumbling for buttons. Green laser visibility outperforms red in most lighting conditions, making this an excellent choice for home defense and range training.

This model mounts directly to the Ruger-57's accessory rail without tools, featuring a low-profile design that maintains the pistol's handling characteristics. Powered by a single 1/3N lithium battery, the unit provides up to 1 hour of constant-on runtime. The ambidextrous activation switch allows manual control when not using INSTANT-ON capable holsters. Constructed from reinforced polymer with a tactical finish.
