Holosun 407K X2

The Holosun 407K X2 is a compact open-emitter pistol optic available with either a red or green 6 MOA dot. Select the preferred reticle color from the available options above. Both versions are designed around Holosun’s K footprint for slimline, subcompact, and micro-compact pistols where a lightweight optic and fast-acquisition reticle are priorities.

The fixed 6 MOA dot creates a bold aiming reference that is easy to locate during the initial presentation and track through recoil. Compared with a smaller precision-oriented dot, the larger reticle favors rapid defensive shooting, close-range target engagement, and concealed-carry applications where speed and visibility are especially important.

The Red model uses a 650nm Super LED, while the Green model uses a high-visibility 540nm Super LED. Both configurations provide ten daylight and two night-vision-compatible brightness settings, allowing the reticle to be adjusted for bright outdoor conditions, reduced light, or use with compatible night-vision equipment.

Shake Awake conserves battery power by placing the optic into standby during inactivity and restoring the previous brightness setting when movement is detected. The programmable shutoff timer can be configured for different inactivity periods or disabled for continuous operation.

A side-loading CR1632 battery tray allows battery replacement without removing the optic from the slide or disturbing its zero. Battery life reaches up to 50,000 hours at brightness setting six, while Memory Function returns the optic to the previously selected brightness level after activation.

Lockout Mode helps prevent unintended button presses from changing the brightness setting during carry or use. The 407K X2 relies on manual brightness control and does not include Solar Failsafe or automatic brightness adjustment, giving the shooter direct control over reticle intensity.

Machined from 7075-T6 aluminum and protected by an anodized black finish, the Holosun 407K X2 weighs just 1 ounce. Its compact body carries an IP67 environmental rating and a 5,000G vibration rating, providing the durability needed for concealed carry, defensive use, training, and everyday range work.

The Holosun K footprint supports direct installation on compatible optics-ready slides. Some pistols with RMSc-pattern cuts may require modification, an adapter plate, or manufacturer-specific mounting hardware, so fitment and screw length should be confirmed before installation.
