The Holosun HE407K-GR X2 is built for shooters who carry compact and subcompact pistols and want fast target acquisition without sacrificing durability or reliability. Designed specifically for concealed carry applications, this open reflex sight delivers a bold 6 MOA green dot in a lightweight, low-profile package that pairs easily with today’s most popular slimline handguns. It’s a practical, hard-use optic that keeps things simple while delivering the features that matter most.
At the center of the HE407K-GR X2 is Holosun’s Green Super LED, producing a crisp 6 MOA dot that’s easy to pick up in bright daylight and stressful, close-range scenarios. The larger dot promotes rapid acquisition and confident shot placement, making it ideal for defensive use and fast presentations. With 12 brightness settings, including 10 daylight and 2 night-vision compatible options, the optic adapts quickly to changing lighting conditions while remaining clear and consistent.
The X2 upgrade introduces Lock Mode, which prevents accidental brightness changes once your preferred setting is selected. This feature is especially valuable for concealed carry, where unintentional button presses can occur during daily movement or holstering. Shake Awake technology ensures the optic is instantly ready by powering on with motion and returning to the last brightness setting used, conserving battery life without compromising readiness.
Machined from rugged 7075 aluminum, the HE407K-GR X2 is built to withstand daily carry and recoil from high round counts. Its open design keeps weight low while maintaining a clear sight picture with parallax-free performance and unlimited eye relief. A side-mounted battery tray houses a CR1632 battery, allowing quick replacement without removing the optic or losing zero. Battery life is rated up to 50,000 hours on a mid-level setting, keeping maintenance to a minimum.
Using Holosun’s K footprint, the HE407K-GR X2 mounts directly to compatible slides such as the P365X and P365XL, and it can be adapted to four-boss slide patterns with the appropriate adapter plate. Compact, durable, and purpose-built, this optic is a strong choice for shooters who want a reliable green-dot sight for everyday carry.
