Special Features
- Solar Failsafe uses the integrated solar panel as both a secondary power source and an ambient light sensor, keeping the reticle fully functional in any lit environment even after the CR1632 battery reaches complete depletion, which removes battery failure as a single point of failure on a carry pistol.
- The Multi-Reticle System gives you three distinct aiming configurations: 2 MOA dot only for precision work, 32 MOA ring only for maximum close-range speed, or the full circle-dot combination for a versatile aiming solution that covers both scenarios without changing mounts or swapping optics.
- The lockout mode disables the brightness adjustment buttons during holster carry, pocket carry, and storage, preventing accidental setting changes from slide manipulation, gear contact, or incidental button pressure during a draw stroke or reholster.
- Shake Awake powers the sight on the instant the pistol moves and shuts off after a selectable inactivity period, keeping the full battery reserve intact between draws, dry fire sessions, and range outings without any manual power management.
- The last setting recall function brings the dot back at your previously used brightness level every time the sight activates, so your intensity setting always matches your environment after transport or storage without cycling through brightness levels before use.
- The side-load CR1632 battery tray allows a complete battery swap without removing the sight from the slide, keeping your mount torque and established zero intact between every battery change without a re-zero session.
Practical Benefits
- The direct fit for Sig P365X and P365XL slides makes the HS507K-X2 a drop-in optic upgrade for two of the most widely carried subcompact pistols on the market with no adapter plate, no extra hardware, and no gunsmithing required.
- The K Series footprint also fits Glock 43X MOS, Glock 48 MOS, Springfield Hellcat, Smith and Wesson Shield Plus, and other popular subcompact MOS slides with the included adapter plate, giving you broad platform coverage from a single sight purchase.
- The solar panel provides automatic brightness adjustment in any lit environment, so the dot intensity stays matched to your lighting conditions without manually cycling through settings between indoor and outdoor use.
- The 1.0 oz total weight adds virtually no perceivable mass to a subcompact carry pistol, keeping your draw weight, holster retention, and concealment profile consistent whether the HS507K-X2 is installed or not.
- Your HS507K-X2 gives you a solar-backed, multi-reticle open reflex red dot on a subcompact pistol that adjusts to ambient light automatically, blocks accidental button changes during carry, and holds zero through hard daily use on the most popular slim-line carry platforms available.
The Holosun 507K X2 Red Dot Sight (HS507K-X2) with its 32 MOA ring and 2 MOA red dot is a reliable pick for concealed carry shooters and subcompact pistol users who want a solar-powered, multi-reticle open reflex sight with lockout mode and side-load battery access purpose-built for slim-line carry platforms and daily defensive use.
