Holosun 407C X3 Open Pistol Sight 2 MOA Gold Dot RMR Footprint - HS407C-X3-GD - UPC 810047074540

Product Description

The Holosun HS407C-X3-GD is an open reflex pistol optic engineered for concealed carry, tactical applications, and competitive shooting. Built around the industry-standard Trijicon RMR footprint, this optic mounts securely to full-size and compact handgun slides or adapter plates without requiring proprietary mounting hardware. Constructed with a reinforced 7075-T6 billet aluminum housing finished in durable black hardcoat anodizing, the X3 generation features a modernized structural architecture designed to efficiently disperse impact forces during harsh operational use.

Driven by an efficient 590nm Gold Super LED emitter, the HS407C-X3-GD projects a crisp 2 MOA Gold Dot reticle. The amber/gold spectrum delivers high-contrast target acquisition against bright backgrounds and in complex lighting where traditional red dots may blur or wash out, making it an exceptional choice for shooters with color vision deficiencies or astigmatisms. Power management is supported by Holosun's Solar Failsafe system, featuring a forward-facing photodiode sensor that reads target-area light conditions to adjust reticle intensity automatically[cite: 1, 2]. Powered by a side-loading CR1632 battery tray, battery swaps can be performed without removing the optic body from the slide, preserving your established zero[cite: 1, 2].

Equipped with Shake Awake™ motion-sensing activation, the optic automatically enters sleep mode during periods of inactivity and instantly reactivates at the slightest movement[cite: 1, 2]. Featuring 12 total brightness settings (8 daylight and 4 night vision compatible) alongside a lockout mode to prevent accidental button adjustments during holstered carry, the HS407C-X3-GD provides duty-grade reliability across dynamic shooting scenarios[cite: 1, 2].

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment Matrix: Fits pistol slides machined for the Trijicon RMR footprint (or aftermarket optic plates designed for standard RMR posts/screw spacing)[cite: 1, 2].

1. Verify the firearm is fully unloaded, clear the chamber, and lock the slide to the rear before beginning installation[cite: 1, 2].
2. Clean the optic cut pocket and threaded mounting holes thoroughly using isopropyl alcohol to remove factory oil and residue[cite: 1, 2].
3. Apply a drop of non-permanent threadlocker (Blue Loctite 242) to the included optic screws. Seat the sight onto the slide posts and torque fasteners evenly to 15 in-lbs using a calibrated torque wrench[cite: 1, 2].
