The Holosun HS507K-X2 Compact Open Reflex Sight is made to be mounted on handguns, specifically those for concealed carry. Its low profile design reduces the risk of snagging and is constructed out of durable 7075 T6 Aluminum. The HS507k-X2 utilizes Shake Awake technology that will keep the display deactivated when not in motion and can be programmed to adjust the length of time it takes for the display to turn off. Alternatively, the Shake Awake system can be turned off completely and stay powered for 50k hours. The HS507K-X2 also features Law Enforcement Model (LEM) programming that provides “Lock Mode,” and “Manual Mode.” Lock Mode will keep accidental button presses from happening when the weapon is being drawn or holstered and Manual Mode gives the user full control over reticle brightness.

Metal, low profile, with the rear backup iron cutouts, a circle-dot reticle (with the option for a regular dot or cicle-only), shake-awake, and the ability to change battery without needing to remount make this feature-wise one of the best pistol dots on the market--as long as you get a functional unit. That said, I haven't yet had an issue with Holosun across 4 different products.

The 507k fits my Hellcat well (with a mounting plate). I really like the 2 moa dot. The optic seems to be well built with quality material.
