This Technology Features:

Four separate, unique modes of operation
The tactical teams wanted it… Now you can have it… Separate modes allow for individual laser recognition in tactical team situations. The 4 modes consist of 1 constant beam mode and 3 pulsing modes. You can always easily change modes while your Viridian is on so that you can quickly and effortlessly select a unique aiming point. Your Viridian green laser sight will remember your mode selection for your next use.

The four laser modes are:


Low Speed Pulse

Medium Speed Pulse

High Speed Pulse

Constant beam mode will always give you the maximum visibility; however, using one of the three pulsing modes will maximize battery life. Battery life will increase from approximately 4+ hours to 7+ hours in the pulsing modes.

Automatic power shut down

In the event the Viridian is accidentally left on, it will shut down in approximately 10 minutes after a brief warning period. If you wish to keep the power on, simply press either button. This will reset the power down timer.

Low-Battery indicator

Once battery power reaches a low level, the Viridian will blink once approximately every 10 seconds. The low battery indicator can be affected by temperature extremes or by using a battery other than those recommended by the manufacturer.


utilize a precise, advanced 635 nm laser wavelength to generate the brightest, sharpest red dot possible, for more positive targeting, higher accuracy, and stronger intimidation in situations where lesser lasers may fade and fail.




Why Viridian?

The Viridian is Purpose-Built

In addition to offering a very powerful green laser, Laser Aiming Systems Corporation designs every product within the Viridian line to perfectly fit specific gun models. This means that each Viridian product captures its visual cues directly from the gun it is designed for as it seamlessly integrates onto the rail and latch bar. By doing so, the Viridian line of green laser sights changes the traditional gun/laser combination from being one of a bulky add-on situation to one of a compact cohesive gun/laser system.

The Viridian is Compact

Many lasers, green or otherwise, are built for rifles and are up to four or five inches long. The Viridian is built for specific handguns and amazingly fits perfectly on your accessory rail. This is an impressive feat given that green lasers require an additional crystal and are much more complex than the standard red ones with their direct injection diodes. We know of no other green laser sight currently on the market that is compacted anywhere near this level! The benefit to you is that this robust laser will become as one with your handgun as it fits snug and secure in front of the trigger guard and below the barrel.

The Viridian Windage & Elevation Adjustments can be Counted On

As many have experienced, not all laser sights on the market have adequately functioning windage and elevation adjustments. With the Viridian green laser you can count on quick and easy Allen wrench adjustments to get your laser zeroed in and to hold a zero.

The Viridian is Easy To Use

Simply slide your Viridian green laser sight onto your accessory rail until it firmly locks into place. Then, as you are in the shooters stance holding your handgun, simply extend your right index finger to locate the Viridian’s On/Off switch to have complete control of the beam of green laser light. 

The Viridian is an Exceptional Value

Due to the added technology and cost, green lasers had previously not been economically or physically feasible for civilian use – especially for handguns. With its launch of the Viridian and its patent-pending internal design, Laser Aiming Systems Corporation has put together the best technology at the best possible price. You can now have a laser sight that emits a perfectly collimated beautiful beam of green light all enclosed within a condensed package. The result is a far superior product at prices comparable to traditional red laser sights.
