The Holosun HS507C X2 is a 1x open-reflex pistol red dot sight on the Trijicon RMR footprint, running the Multi-Reticle System behind a 0.91 x 0.63 in window.
The switch between a fast 32 MOA circle and a precise 2 MOA dot is a button press, not a parts change — the same sight covers a close, quick target and a slow, small one.
Holosun build it in 7075-T6 aluminium, rate it IP67, and it measures 1.78 x 1.15 x 1.15 in and weighs 1.5 oz. The 650nm red Super LED runs from a CR1632 in a side-loading tray, rated to 50,000 hours at setting 6, with Solar Failsafe drawing supplemental power from ambient light and Shake Awake sleeping the reticle when the gun has been still. Lockout Mode keeps the settings where you left them.
Adjustment is 1 MOA per click with 50 MOA of travel each way, eye relief is unlimited and the sight is parallax-free, so head position behind the glass is not critical. There are 10 daylight brightness settings and 2 night-vision levels. The footprint is the thing to check before you order: this is the RMR pattern, not the smaller RMSc one, so a slim-slide pistol needs the K-series body instead. Holosun also write the part number as HS507C-X2-RD on their current page.
It mounts to RMR-cut slides and to any optics-ready pistol supplied with an RMR-pattern plate, as well as RMR-pattern mounts on carbines. For the fixed-chevron reticle instead of the switchable one, see the HS507C X2 ACSS Vulcan; for a narrower slide the HS507K X2 carries a similar sight on the smaller pattern.
