Holosun HS507C-X2 Red Dot Pistol Sight

The Holosun 507C (HS507C-X2) is an open reflex red dot sight designed for full-size pistol applications, and one of the most popular pistol optics on the market for its combination of features and value. It features an RMR footprint, making it compatible with a wide range of optics-ready handguns including Glock MOS, Sig P320, Walther PDP, S&W M&P, and many others with an RMR-cut slide or adapter plate.

The 507C-X2 uses Holosun’s Multi-Reticle System (MRS), which lets you toggle between a 2 MOA dot, a 32 MOA circle, or both together without re-zeroing. The large circle helps you pick up the dot fast at close range while the 2 MOA dot gives you precision when you need it. Solar Failsafe keeps the optic running on ambient light if the battery dies. Shake Awake powers the LED on when it detects motion and off when it does not, so the sight is always ready when you pick up the gun.

The X2 version adds Lock Mode to prevent accidental button presses while holstered, and a side-loading battery tray so you can swap the CR1632 without removing the optic from your slide. The housing is machined from 7075 T6 aluminum with a hardcoat anodized finish.
