Holosun EPS Enclosed Pistol Sight – Green Reticle

The Holosun EPS (Enclosed Pistol Sight) is a compact, enclosed-emitter pistol optic designed for shooters who demand reliability, durability, and consistent performance in everyday carry and defensive handgun applications. As the latest addition to Holosun’s proven pistol-optic lineup, the EPS builds on the success of the popular 407 and 507 series, bringing full-size optic technology into a pistol-ready footprint.

Holosun earned its reputation by introducing advanced features—such as multiple reticle systems, Shake Awake™ technology, solar-assisted power redundancy, and automatic brightness adjustment—at an accessible price point. The EPS continues that mission with a refined design focused on real-world reliability and environmental protection.

Fully Enclosed Emitter Advantage

Unlike traditional open-emitter pistol optics, the EPS features a fully enclosed emitter system. This design protects the emitter from dust, debris, sweat, rain, and environmental contaminants that can obscure the dot on open systems. The result is a clear, crisp, and uninterrupted reticle in adverse conditions, during daily concealed carry, or under extended use.

Lightweight, Durable Construction

The EPS is precision-machined from 7075-T6 aluminum and finished with a hardcoat anodizing for exceptional strength and wear resistance. Weighing approximately 1 ounce, it adds minimal mass to the slide, making it an excellent option for concealed carry pistols without compromising durability.

Power & Visibility

Powered by a CR1620 battery with up to 50,000 hours of battery life, the EPS also incorporates a built-in solar panel for added power redundancy. Both automatic and manual brightness adjustment allow the optic to adapt to changing lighting conditions seamlessly.

The EPS offers multiple reticle options, giving shooters flexibility based on preference and application:

• 2 MOA dot

• 2 MOA dot with 32 MOA circle

• 32 MOA circle only

Mounting Compatibility

The Holosun EPS uses the Holosun K-Series footprint and includes an RMR adapter plate, expanding compatibility across many optics-ready pistol platforms.

Footprint Compatibility Notice
