Description
The Holosun HS407K X2 is a streamlined, purpose-built open-reflex sight designed for concealed carry and everyday carry pistols. Where the 507 series offers multiple reticle options, the 407K X2 keeps things simple and fast with a single bold 6 MOA red dot — giving defensive shooters a clean, no-fuss aiming solution built around speed and reliability. Finished in a durable black anodized coating over a 7075-T6 aluminum housing, this optic is engineered to take a beating while adding minimal bulk to your carry pistol.
Compact, No-Nonsense Design
With a sight window measuring approximately 0.58″ x 0.77″ and a weight of just 1 ounce, the HS407K X2 is built on Holosun’s K-series footprint — closely related to the modified RMSc pattern. It’s a documented direct fit for popular slim and subcompact pistols like the SIG P365X/XL, with adapter plates available for other optics-ready cuts. The low, streamlined housing keeps the sight tucked close to the slide, preserving a smooth holster draw and a low overall profile.
Bold 6 MOA Dot for Speed
The HS407K X2 is built around a single, crisp 6 MOA red dot reticle. This larger dot size is specifically suited for fast target acquisition at typical defensive handgun distances, where speed matters more than pinpoint precision. Shooters get an aiming point that’s quick to find and easy to track through recoil, making it a natural choice for concealed carry, home defense, and everyday carry applications.
Super LED Technology and Long Battery Life
Powered by Holosun’s efficient Super LED emitter (650nm), the HS407K X2 produces a bright, clean dot with minimal battery draw. Rated for up to 50,000 hours of battery life on a single CR1632 battery, this optic is built to go the distance without frequent battery swaps. A convenient side-mounted battery tray allows for quick, tool-minimal battery changes without ever removing the optic from your slide — meaning your zero stays intact between changes.
