Holosun 407C X3

• 2 MOA green dot: the compact dot is easy to pick up quickly, while the green reticle stands out well in bright daylight and against visually busy backgrounds.
• RMR footprint compatibility: the widely used mounting pattern simplifies slide and plate selection, making this optic easier to integrate on many pistol setups.
• Solar Failsafe and Shake Awake: automatic brightness support and motion-activated wake-up help keep the sight ready in changing light while reducing unnecessary battery drain.
• Side-loading CR1632 battery: the battery can be replaced without removing the sight from the slide, so zero is not disturbed during routine maintenance.
• 7075-T6 aluminum housing: the reinforced body, IP67 protection, and 5000G vibration rating give the sight the durability needed for carry, duty, and regular range use.

About the Holosun Reflex Series

Holosun Reflex sights are built around the company’s compact open-emitter red-dot concept for fast target acquisition on modern firearms. Within Holosun’s lineup, the series spans models for pistol use as well as larger-format reflex sights intended for carbines, pistol-caliber carbines, and shotguns. The family is defined by a low-profile design, a wide viewing window, and electronics aimed at practical field use rather than unnecessary complexity.

Across the series, Holosun has combined features such as Shake Awake, Solar Failsafe, and different reticle formats depending on the model. Some versions use a simple dot for a clean sight picture, while others add the company’s Multi-Reticle System for shooters who want a circle, dot, or combined aiming reference. In practical terms, the series is known for compact dimensions, durable metal housings, and controls that support both fast defensive shooting and regular training. That makes Holosun Reflex sights a common choice for users who want a lightweight optic with modern brightness management, dependable battery performance, and mounting standards that fit established pistol and tactical optics ecosystems.

About the Holosun 407C X3

The Holosun 407C X3 is a 1x open reflex sight built for pistol applications where speed, low mounting height, and a clear sight picture matter most. This version uses a 2 MOA green dot, which gives a precise aiming point without covering too much of the target and can be especially easy to distinguish in strong daylight. Because it uses the Trijicon RMR standard footprint, it fits a broad range of slides and mounting solutions already set up for one of the most common handgun optic patterns.

The optic is designed to stay practical in daily use. Solar Failsafe works with automatic brightness control to help the reticle remain visible as ambient light changes, while manual brightness adjustment with lockout mode allows the user to secure the chosen setting against accidental button presses. Shake Awake adds another layer of convenience by waking the sight when movement is detected and powering it down during inactivity. The side-loading CR1632 battery supports long service intervals and can be changed without removing the sight from the firearm.

Mechanically, the 407C X3 combines a compact 16x23 mm window with a reinforced 7075-T6 aluminum housing that keeps weight low while improving resistance to recoil and hard use. The 1 MOA click adjustments and ±30 MOA windage and elevation range provide straightforward zeroing, and the IP67-rated, fogproof, and shockproof construction makes the sight suitable for carry, training, and demanding outdoor conditions.
