Holosun HS407C-X3-RD 2 MOA Red Dot

The Holosun HS407C-X3 2 MOA red dot answers the question every optics-ready pistol owner eventually asks: how do you get RMR-footprint reliability without babysitting a battery? Because the HS407C-X3-RD builds on the proven 407C platform, shooters already trust the core formula, and Holosun uses this update to reinforce the housing, refine the brightness system, and tighten up the overall package. Since the optic runs on the industry-standard RMR footprint, it drops onto a wide range of optics-ready slides without a proprietary mounting headache. As a result, the Holosun HS407C-X3 2 MOA dot works equally well as a duty sight, a range optic, or an everyday-carry companion.

Beyond the footprint, the sight’s Solar Failsafe system uses a forward-facing photodiode to track ambient light and keep the reticle visible whether you’re on an indoor range or stepping out into full sun. In addition, Shake Awake technology powers the optic on the moment the pistol moves and lets it rest when it doesn’t, which stretches the CR1632 battery’s runtime considerably. Because the battery loads through a side tray, changing it never requires pulling the optic off the slide or re-zeroing afterward. The HS407C-X3-RD stays ready for use without asking the shooter to think about it.

Why This Product Stands Out

The 407C line earned its reputation with shooters who carry daily and train often, and the X3 generation builds on that foundation rather than reinventing it. Since Holosun reinforced the housing in 7075-T6 aluminum, the optic holds up to the kind of holster wear and recoil cycling that eventually reveals a weak point on lesser sights. Furthermore, the IP67 rating and 5000G vibration resistance mean the HS407C-X3-RD keeps working through rain, sweat, and the abuse of a duty belt, not just a clean afternoon at the range.

What separates this optic from a basic red dot is how little it asks of the shooter day to day. Because Solar Failsafe and Shake Awake work together in the background, the dot is simply on when you need it and conserving power when you don’t. That’s why shooters moving up from an older 407C or a competitor’s RMR-pattern sight tend to notice the difference immediately: less fiddling with brightness, fewer dead-battery surprises, and a sight picture that stays consistent from a dim garage to bright daylight.

Ideal Use Cases

• Concealed carry and everyday carry pistols
• Duty and professional use
• Competition and range training
• Home defense pistols running an optics-ready slide

Compatibility Information

Optic-Ready Pistol Slides: The HS407C-X3-RD mounts directly to any slide cut to the industry-standard RMR footprint. Since TX Arms cannot confirm fitment on every optics-ready pistol without a plate or adapter, check your specific slide cut against the RMR pattern before ordering, or contact TX Arms to confirm fitment on your platform.
