Description
The Viridian E Series brings laser aiming capability to your P365 or P365XL without any gunsmithing or permanent changes. This is a trigger-guard-mounted sight engineered to keep your carry gun low-profile while giving you real advantages when it counts. The laser delivers solid visibility at close range during the day and reaches out to a mile at night, which covers the realistic distance window most people train and carry in.
Installation and Design of the E Series
What stands out here is how straightforward installation is. The sight comes with an Allen wrench and mounts directly to your trigger guard in just a few minutes. The housing is durable polymer, compact, and integrates with the P365 so naturally it looks like Viridian built it specifically for this gun, which they did. The overall weight adds less than an ounce to your setup, so you won't notice any shift in how the pistol handles or points.
The E Series includes user-adjustable windage and elevation, giving you the flexibility to dial it in to your sights. An ambidextrous on/off button works equally well for both hands, and the 5-minute automatic shutoff feature protects battery life if you forget to power down. The sight operates on a single 1/3N battery that runs for over 6 hours continuous use.
Why the Included Holster Matters
Viridian includes a Kydex IWB holster shaped and cut for the P365 with this laser mounted. That's important because a trigger-guard laser needs the right holster or it becomes uncomfortable and unreliable. This Kydex piece is engineered to work with your draw mechanics and retains the gun securely without printing through clothing. Right-hand carry comes standard.
Trigger-guard mounting is one of the most practical designs for concealed carry. Your gun stays low-profile, the laser doesn't interfere with your grip, and the laser sits in a natural position for quick access. This sight delivers rapid target acquisition when you need it most without adding snag hazards or bulk.

Frequently Asked Questions
Will the E Series red laser work on other Sig models besides the P365?
No, the E Series is model-specific and designed exclusively for the P365 and P365XL. Viridian makes different E Series configurations for other firearms like the Hellcat, M&P Shield, and others, but this particular laser is calibrated only for these Sig platforms.
How difficult is installation?
Installation is straightforward and takes just a few minutes with the included Allen wrench. The laser mounts directly to the trigger guard with no gunsmithing or permanent modifications required. Most people have it mounted and zeroed in under 10 minutes at home.
Can I use my existing IWB holster with this laser?
Probably not. Trigger-guard-mounted lasers need specific holster cuts to function properly and provide retention. Viridian includes a custom Kydex holster engineered for this laser mounted on your P365, so you're set out of the box. Using a generic holster risks both comfort and reliability.
How visible is the red laser in bright daylight?
Red lasers are less visible than green in daylight, which is why Viridian also makes a green E Series model. The red version performs best indoors or at night, where the red dot stands out clearly. At 25 yards in daylight, you can still see it, but a green laser would be more vivid in bright sun.
