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.

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.

Put it in a p365x macro and it’s great. Multiple reticle options is nice and I actually run the donut with no dot, which I would have said no way to prior to owning it. Side battery is great. Holds zero. Nothing to complain about.

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.

Great Red dot. Easy to acquire targets. Having three different radical options it's also a plus.

Sadly this optic failed after 220 rounds. Something internal broke sending the zero to its lowest setting that cannot be adjusted by turning the adjustment dial to the highest position. Something else to note is that Holosun's electronic warranty has not been working since buying the optic on January 30th. Something tells me this just turned into a $300 paperweight. Otherwise the optic fit nicely on my 9mm Dagger with the use of an adapter plate.

optic failed after a couple hundred rounds, i like the set up of this optic and want to like it but the internals are poorly built and now the optic can only get brighter and has no option to dim due to something breaking internally on it. I was not even hard on the optic it was taken care of and only fired lightly and the range when it began to fail.

Mounted the HS507K X2 on my Ruger Max 9 fit perfectly. Really like the recital options.

Using O light wipes out red dot, must use iron sights or green laser is only drawback.
