Holosun HE407K-GD X2 Subcompact Pistol Reflex Sight - 6 MOA Gold Dot - HE407K-GD-X2 - UPC: 810047074236
Product Description
The Holosun HE407K-GD X2 is an open-reflex optical sight engineered specifically for concealed carry and subcompact pistol platforms. Utilizing Holosun’s high-efficiency Super Gold LED technology, the sight projects a crisp 6 MOA gold dot reticle. Gold illumination provides an optimal high-contrast aiming point that stands out against varied target backgrounds while proving particularly beneficial for shooters with red-green color blindness or eye fatigue issues associated with standard red reticles.
Constructed from CNC-machined 7075-T6 aluminum with an anodized black finish, the HE407K-GD X2 features a modified RMS-c footprint (Holosun K-footprint) that mounts directly onto popular slimline slides such as the Sig Sauer P365XL or optics-ready subcompact handguns. Built-in Lock Mode disables manual button operation to prevent accidental brightness adjustments while holstered, while Shake Awake technology activates the LED instantly upon motion sensing and powers down during static periods to conserve battery life.
Powered by a single CR1632 battery, the side-mounted battery tray allows for battery swaps without removing the sight from the slide, preserving optical zero. With 12 brightness settings (10 daylight and 2 night-vision compatible) and up to 50,000 hours of continuous runtime, the HE407K-GD X2 provides dependable aiming speed and reliability for daily defensive carry.
