🎯 Quick Fit & Compatibility Guide

Mounting Footprint Standard: Holosun K-Footprint (Modified RMSc pattern without rear recoil lugs).

Direct Slide Mounting: Mounts directly onto modern micro-compact, optics-ready factory slides including the Sig Sauer P365X/XL/X-Macro, Springfield Hellcat OSP, Smith & Wesson Shield Plus / Equalizer, and the Taurus 856 T.O.R.O. revolver series. Note: Glock 43X MOS and Glock 48 MOS slides can accept this optic directly if the slide's minor rear indexing nubs are filed down, or via a slimline adapter plate (sold separately).

Holster Cross-Compatibility: Form-fitted profile seamlessly clears advanced concealment holsters engineered for micro-optics, including the PHLster City Special, PHLster Pro Series, and PHLster Skeleton lines.

🛠️ Premium Technical Features

Multi-Reticle System (MRS): Adapt your sight picture to your specific threat environment. Cycle instantly between a highly precise 2 MOA center aiming dot for distance accuracy, a wide 32 MOA circle for rapid close-quarters indexing, or run both simultaneously as a classic circle-dot reticle.

Shake Awake Technology: Never fumble with an off-switch during an emergency. Holosun’s advanced motion-sensing technology automatically sleeps the LED during periods of complete stillness to preserve power, waking up instantaneously to your exact last brightness setting the micro-second it detects weapon movement.

Convenient Side-Loading Battery Tray: Features a low-profile, side-mounted battery drawer. This allows you to easily swap out your coin-cell battery without ever removing the optic housing from your handgun slide, completely eliminating the annoying chore of unmounting your red dot and re-zeroing your point-of-impact at the range.

Engineered to Survive: CNC milled from ultra-strong, combat-grade 7075-T6 aluminum and hard-coat anodized. The housing is completely vibration-tested to survive 5,000 Gs of violent recoil shock and features a rugged IP67 waterproof certification to shrug off heavy rain, mud, and corrosive daily body sweat.

Button Lockout Mode: Built specifically for standard inside-the-waistband (IWB) carry. Activating Lock Mode safely freezes your brightness button settings, preventing clothing friction or holster walls from accidentally bumping or altering your illumination intensity.

12 Custom Brightness Levels: Features 10 high-visibility daylight levels and 2 dedicated, ultra-low settings fully compatible with night-vision generation units. Delivers up to 50,000 hours of continuous runtime on a single CR1632 battery.

Frequently Asked Questions

What is the difference between this K-footprint and a standard Shield RMSc footprint? The Holosun K footprint shares the exact same screw-hole spacing as the popular Shield RMSc standard. However, Holosun eliminated the deep rear recoil alignment holes on the bottom of the optic frame. If your pistol slide has four tall upright indexing pins milled into the metal, you will simply use a thin adapter plate to bridge the gap or have a gunsmith smoothly flush the rear lugs.

Does this optic feature a solar panel backup? No. The HS507K X2 relies entirely on its side-loading CR1632 battery cell. Because it utilizes Holosun’s incredibly efficient Super LED emitter paired with automated Shake Awake motion-sleep cycles, a single, highly affordable battery provides up to 5,000 days (50,000 hours) of reliable operational life before requiring a tool-less swap.

Can I manually change the reticle style, or does it stay stuck as a circle-dot? You can customize it completely to your personal preference. By simply pressing and holding the "-" button for three seconds, you can cycle through three clean visual profiles: the 2 MOA dot alone for a crisp target picture, the 32 MOA ring alone for maximum speed, or the combined circle-dot reticle for the best of both worlds.
