Holosun HS407C X2 Open Reflex Red Dot Sight for Pistols 2 MOA

Holosun HS407C X2 Reflex Sight 

The Holosun HS407C X2 is an open reflex sight for pistols, developed for full-size and compact handgun setups where the user wants a simple, fast, and reliable 2 MOA red dot without unnecessary complexity. The model uses a precise 2 MOA red aiming point, which makes it a strong choice for more exact shot placement, sport shooting, defensive use, and shooters who prefer a cleaner sight picture without a circle or multi-reticle system.

One of the key strengths of the HS407C X2 is the combination of an open emitter design, a large viewing window, and low weight, which helps with faster dot acquisition and a more natural draw-to-sight picture. This open optic format is especially useful for shooters who want a wide field of view, a familiar pistol red dot layout, and efficient handling for range work, dynamic shooting, and defensive training.

The housing is made from 7075-T6 aluminum and uses a side-mounted battery tray, allowing the CR1632 battery to be replaced without removing the optic from the slide. Holosun also includes Solar Failsafe, Shake Awake, and Lock Mode in this model, giving the user a practical balance of battery efficiency, security against accidental setting changes, and day-to-day usability.

The HS407C X2 offers up to 50,000 hours of runtime on setting 6, 10 daylight and 2 night vision brightness settings, IP67 water resistance, and 5000G vibration resistance. That makes it a serious option for active handgun use, especially for customers looking for a dependable optic at competitive pricing with delivery across Europe from Professional Optics in Split, Croatia.

This model uses the industry-standard Trijicon RMR footprint, which makes installation easier on a wide range of optic-ready slides and adapter plates that support this pattern. For shooters who want a proven open pistol red dot without the extra weight of an enclosed design, the HS407C X2 is a very practical and cost-effective choice.

The clean 2 MOA dot is especially well suited to shooters who want an uncluttered sight picture and more precise aiming on smaller targets or at longer handgun distances.

Mounting and use

The HS407C X2 is intended for users who want an open pistol red dot on an RMR-footprint slide or on a compatible mounting plate. Because it follows the standard Trijicon RMR pattern, it is a practical option for a wide range of modern handgun slides, sport pistols, and defensive setups.

The side battery tray is one of the most practical features of this model because it allows battery replacement without removing the optic and without needing to repeat the entire zeroing process after every battery change. That matters for users who train regularly and want easier maintenance with less downtime.

In real use, the 2 MOA dot provides a very clean sight picture and works well for shooters who want more precise aiming on smaller targets or at longer pistol distances. Solar Failsafe and Shake Awake add further convenience by helping the optic stay ready for use while managing power efficiently.
