HOLOSUN HE407C-GR X2 / HS407C X2 2 MOA Dot Open Reflex Sight - Durable

In this review of the HOLOSUN HS407C X2 open reflex sight, the bottom line is simple: it is built for shooters who want a compact, rugged pistol optic with a crisp 2 MOA dot and exceptionally long battery life. The sight's combination of Solar Failsafe, Shake Awake technology and a side-mounted CR1632 battery tray makes it a practical choice for duty or range use, while the parallax-free 1x view and large 0.63 x 0.91 window help speed target acquisition on full-sized handguns.

Key Features

• 2 MOA Dot: The precision 2 MOA reticle gives a small aiming point that helps with accurate shots at common handgun distances.
• Solar Failsafe: Backup power from ambient light keeps the reticle visible if the battery fails, useful in varied light conditions.
• Shake Awake Technology: The optic conserves battery by deactivating the LED when idle and instantly wakes with the slightest movement.
• Durable Construction: 7075 T6 aluminum housing and anodized finish provide strength and resistance to harsh environments.
• Long Battery Life: Holosun's Red Super LED and power management yield up to 50,000 hours of battery life under typical use.
• Easy Maintenance: Side-mounted CR1632 battery tray allows quick replacement without removing the sight from the pistol footprint.

Who It's For

The HS407C X2 is best for handgun owners who want a rugged, low-profile open reflex sight for full-sized pistols, including range shooters and those seeking a duty-style optic with reliable battery management. The small 2 MOA dot and large viewing window suit shooters focused on fast target acquisition with fine enough precision for defensive and competition work.

Shooters who need magnification, multi-reticle complexity, or an ultra-minimal footprint for subcompact pistols may want to consider other optics. Also, those preferring only night-vision specific reticle modes should confirm the model variant matches their needs.

Pros & Cons

Pros

• Crisp and clear 2 MOA dot that is easy to pick up, especially in daylight conditions.
• Excellent battery life and sensible power backup via Solar Failsafe for reliability in the field.
• Robust 7075 T6 aluminum build with an industry standard footprint and convenient side battery tray.
• Shake Awake conserves power while ensuring rapid readiness when drawn.

Cons

• Open reflex design may expose the emitter to debris more than enclosed tube optics in extreme environments.
• Not a magnified optic, so shooters wanting zoom or longer-range precision will need a different sight.
