Holosun HS407K-X2-FDE Sub Compact Red Dot Sight Shake Awake 6 MOA
Holosun HS407K-X2-FDE — Open Micro Red Dot for Subcompact Pistols
The Holosun HS407K-X2-FDE is an open-reflex micro sight built specifically for subcompact concealed carry pistols. The X2 revision brings horizontal button layout, a side-loading battery tray, and Lock Mode — all in a Flat Dark Earth anodized finish — while keeping the total weight at just 28 g (1 oz). It is one of the most compact and lightweight pistol optics available for the RMSc footprint.
Housing and Build
The body is precision-machined from 7075-T6 aircraft-grade aluminum with hard anodizing in FDE. Dimensions are 40.6 × 24.9 × 24.1 mm — a footprint that fits flush on subcompact slides without protruding beyond the pistol's outline. Rated IP67 for full dust resistance and short water submersion. Vibration resistance is rated to 5000 G, capable of handling the slide recoil of centerfire pistols and the heavier impulse of shotgun mounts.
Reticle
The 6 MOA red dot at 650 nm is optimized for fast target acquisition at defensive distances. A 6 MOA dot subtends roughly 6 inches at 100 yards — large enough to snap to instantly under stress, while still allowing accurate shots within the 5–25 m range typical of personal defense and IPSC scenarios. The sight is parallax-free with unlimited eye relief, supporting a wide range of shooting positions.

X2 Features: Lock Mode, Shake Awake, Side Battery Tray
Horizontal button layout — the brightness adjustment buttons are repositioned horizontally on the X2, making them easier to operate cleanly with gloves and less prone to accidental activation when drawing from a holster.
Lock Mode disables both brightness buttons simultaneously to prevent unintended setting changes during carry, in a bag, or under tactical contact. Activated by holding both buttons at the same time.
Shake Awake cuts the LED after 10 minutes to 12 hours of inactivity (user-configurable) and restores it immediately upon detecting movement. The last manually set brightness level is retained in memory. A low-battery warning activates by flashing the dot.
Side-loading battery tray allows CR1632 replacement without dismounting the optic from the pistol's slide — a key maintenance advantage for duty or EDC users.
Installation and Zeroing
The HS407K-X2 uses Holosun's K footprint — a modified RMSc standard. Direct installation (no adapter) on: SIG Sauer P365X, P365XL, Canik TP9 Elite SC, Taurus GX4/GX4 XL T.O.R.O., Ruger Max-9. For Glock MOS and RMR-milled slides, Holosun adapter plates are required. Windage and elevation adjust at 1 MOA per click within a ±30 MOA range. Zero at 10–15 m is standard for defensive pistol distances. An included multi-tool handles all mounting and adjustment tasks.
Field Applications
Concealed Carry (EDC/CCW). The low-profile design clears standard holsters without snagging. FDE coloring integrates naturally into earth-tone tactical setups. The 6 MOA dot delivers sub-second sight picture acquisition under stress.
IPSC / USPSA / Practical Shooting. The open design maximizes field of view for fast transitions between targets. The large dot is ideal for drawing and engaging quickly during timed stages.
Airsoft. Platforms with factory RMSc-milled slides accept the HS407K-X2 directly, making it a popular choice for realistic, competition-grade pistol builds.
