Holosun HS407K X2 Red Dot Sight

The Holosun HS407K X2 red dot sight is an open reflex optic purpose-built for concealed carry pistol applications, delivering fast aiming in a slim, dependable package. Compact and carry-focused, the Holosun HS407K X2 red dot features a bright 6 MOA dot, Holosun’s efficient Super LED, and the brand’s proven Shake Awake technology. It is designed to disappear on a subcompact slide while still giving you a quick, clear aiming reference. For everyday carry shooters who want proven performance at a fair price, the 407K is a go-to choice.

What the Holosun HS407K X2 red dot is and who it is for

This is an open reflex micro red dot built specifically for concealed carry pistols, especially slim and subcompact models. Its compact size keeps the gun easy to carry and quick from the holster, while the open design offers a wide, uncluttered view. Carriers who want a simple, reliable dot without unnecessary features will appreciate its focus.

The 6 MOA dot is a deliberate choice for carry, because a larger dot is faster to find and align under stress. That makes the 407K especially well suited to defensive shooting, where speed of acquisition often matters more than fine precision. It is a straightforward optic that does its main job very well.

Key features that stand out

The HS407K X2 keeps the essentials sharp for concealed carry.

• Open reflex design purpose-built for concealed carry pistols
• Bright 6 MOA dot for fast acquisition and quick alignment under stress
• Holosun Super LED with up to 50,000 hours of battery life
• Shake Awake technology that wakes the dot on movement to save power
• Compact, low-profile footprint suited to slim and subcompact slides
• Dependable construction from a brand trusted by everyday carriers

Specifications and what they mean

The 6 MOA dot defines this optic, and its size is tuned for speed rather than long-range precision. On a carry pistol used at close, defensive distances, a bold dot lets your eye lock on fast and align the shot quickly. That is exactly the priority for a concealed carry sight.

The Super LED paired with up to 50,000 hours of battery life means you can rely on the optic for years without constant battery worry. Shake Awake extends that runtime further by putting the dot to sleep during inactivity and waking it the moment you move the gun. Together they deliver the kind of always-ready performance carry demands.

There is a reason the Holosun HS407K X2 red dot has become a default recommendation for new optic-ready carriers. It delivers the features that matter, a bright dot, long battery life, and Shake Awake power management, at a price that leaves room in the budget for a holster and range ammo. The open reflex design gives a wide, uncluttered view that pairs naturally with a fast draw, and the 6 MOA dot is easy to find under stress. Mount it on a subcompact, zero it, and you have a dependable carry setup that will run for years on a single battery.

Mounting, care, and everyday use

Mount the 407K on a compatible optics-ready slide or plate, torque the screws to spec with thread locker, and confirm zero on paper before you carry. Pair it with suppressor-height sights if you want a co-witness backup. Practice your draw so the 6 MOA dot appears in your line of sight automatically.

Maintenance is simple. Keep the lens clean, check screw torque now and then, and swap the battery on a schedule. To round out your carry rig with a holster, sights, or a light, browse the full optics lineup at Outpost Firearms.
