The Holosun HE407K-GR X2 is a compact green dot sight engineered for subcompact and micro pistols where slide real estate is precious and durability is non-negotiable. If you're running a single-stack carry gun or a compact duty pistol and want a fast, reliable aiming point without the weight and complexity of a magnified optic, this is a serious contender. The HE407K-GR X2 builds on Holosun's proven K-footprint design with thoughtful refinements: a green Super LED that delivers up to 50,000 hours of battery life, the new Lock Mode feature that prevents accidental brightness or mode changes when you need the sight to stay put, and Shake Awake technology that conserves battery by powering down until motion wakes it up.
Build quality here is uncompromising—7075 aluminum construction keeps weight minimal while standing up to hard use, whether that's daily carry, competition, or duty work. The 6 MOA dot is crisp and fast on target, and the parallax-free design with unlimited eye relief means you can acquire your sight picture from any shooting position. Brightness management gives you 12 settings total: 10 daylight levels for everything from shade to full sun, plus 2 night vision compatible settings for low-light work or with NV gear. The side-mounted battery tray housing a 1632 cell makes swaps quick and fieldable—no need to remove the sight or fight a recessed compartment when your battery's time is up.
This is the optic for shooters who value reliability, simplicity, and proven performance. No frills, no gimmicks—just a robust green dot that fits tight spaces and stays where you put it.

Frequently Asked Questions
What pistols does the HE407K-GR X2 fit?
The HE407K-GR X2 uses Holosun's K-footprint mounting pattern, which is designed for subcompact and micro pistol slides. Check your specific pistol's optics cut or compatibility list to confirm fit, but this sight is engineered for single-stack carry guns and compact duty platforms.
How long does the battery last?
On Setting 6, you can expect up to 50,000 hours of battery life from the 1632 cell. The Shake Awake feature automatically powers down the sight when there's no motion, significantly extending battery runtime in real-world carry use. The side-mounted battery tray makes replacement quick and hassle-free.
What is Lock Mode and why would I use it?
Lock Mode locks the buttons on the sight, preventing accidental changes to brightness settings or modes during carry or in a holster. If you find your ideal brightness setting, Lock Mode keeps you from inadvertently adjusting it while drawing or reholstering.
Can I use this sight with night vision equipment?
Yes. The HE407K-GR X2 includes 2 night vision compatible brightness settings, so it will work alongside NV devices for low-light training or duty applications.
