The Holosun HS407K X2 is a compact red dot sight purpose-built for concealed carry pistols and subcompact slides where space is precious. At just 0.58" × 0.77", it's one of the smallest reflex optics on the market—small enough to coexist with quality iron sights, yet proven reliable on everything from single-stack 9mms to modern duty guns. If you're tired of bulky red dots that overhang your slide, this is the answer.

The HS407K X2 runs Holosun's Super LED technology and pushes an impressive 50,000 hours of battery life on setting 6—meaning you can mount it, set it, and genuinely forget about the battery for years. The 6 MOA dot is clean and fast for self-defense distances while remaining precise enough for accurate shot placement. Shake Awake keeps the emitter dormant until your draw, extending runtime even further and eliminating the "always-on" drain. A convenient tray-style battery compartment makes swaps simple, and 12 brightness levels (10 daylight, 2 night-vision compatible) let you dial in the perfect brightness for any light condition without hunting through a menu.

Parallax-free performance and unlimited eye relief mean no point-of-aim shift as your cheek weld or shooting position changes—a real advantage in a defensive draw where your sight picture isn't always textbook. The black anodized finish is durable and low-profile, blending seamlessly with modern pistol aesthetics. Whether you're carrying daily, running drills at the range, or building a backup carry gun, the HS407K X2 delivers real-world reliability in a footprint that doesn't compromise your concealment or ergonomics.
