Holosun HS507C-X3 1x 2 MOA Red Dot/32 MOA Circle Multi-Reticle Reflex Sight - RMR Footprint - Black Anodized

The Holosun HS507C-X3 is a 1x open-reflex pistol optic purpose-built for full-size duty, carry, and competition pistols. Its redesigned flat-top housing sets it apart from the previous X2 generation, giving the optic a cleaner sight picture and a lower-profile deck. The sight uses the industry-standard RMR footprint, so it drops onto existing RMR-cut pistol slides and compatible aftermarket mounting plates without modification.

At the core of the HS507C-X3 is Holosun's signature Multi-Reticle System (MRS), letting the shooter cycle between a crisp 2 MOA red dot, a fast-pickup 32 MOA circle, or both combined for close-quarters work. The red reticle is powered by a long-life CR1632 battery rated for up to 100,000 hours of runtime on the 2 MOA dot setting. Solar Failsafe provides automatic brightness backup if the battery is depleted, while Shake Awake wakes the optic on motion and puts it to sleep at rest to preserve battery life.

The housing is machined from 7075 T6 aluminum with a durable black anodized finish and carries an IP67 waterproof rating, making the sight equally at home on a holstered carry pistol or a competition rig. Lockout Mode prevents accidental brightness changes, and side-mounted controls keep adjustments accessible without breaking grip. The HS507C-X3 measures 1.78" long x 1.31" wide x 1.1" tall for a compact, low-print addition to a pistol slide.
