Special Features
The Holosun K Series footprint removes the rear recoil lugs present on standard RMSc designs, which allows Holosun to fully seal the housing to IP67 waterproof standard, a rating that most RMSc-footprint open reflex sights in this size class cannot match.
The Multi-Reticle System gives you three distinct aiming configurations: 2 MOA dot only for precision work, 32 MOA ring only for maximum speed at close range, or the full circle-dot combination, all selectable without tools or removing the sight from the pistol.
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.
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.
Practical Benefits
The direct fit for Sig P365X and P365XL slides makes the HE507K-GR-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 540nm green wavelength sits at the peak of human visual sensitivity, helping your eye find and lock onto the dot faster than a red variant under the same lighting conditions, which translates to faster acquisition on a rapid draw from concealment.
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 HE507K-GR-X2 is installed or not.
Your HE507K-GR-X2 gives you a fully waterproof, multi-reticle open reflex green dot on a subcompact pistol that stays locked on your last brightness setting, blocks accidental button changes during carry, and holds zero through hard daily use.
The Holosun 507K Elite Green Dot Sight (HE507K-GR-X2) with its 32 MOA ring and 2 MOA green dot is a confidence-building choice for concealed carry shooters and subcompact pistol users who want a lightweight, waterproof, multi-reticle open reflex sight purpose-built for slim-line carry platforms and daily defensive use.
