The Holosun 507COMP X3 Green Dot Open Pistol Sight brings Holosun’s proven 507C platform into a larger, competition-focused package. Built on the RMR footprint with a rugged 7075-T6 aluminum housing and hard anodized finish, it pairs a generous viewing window with a bright green Multi-Reticle System that lets you run a precise 2 MOA dot, a fast 32 MOA circle, or both together. Solar Failsafe, Shake Awake, and side-tray CR1632 power keep the sight ready with minimal maintenance.

This 1x open reflex sight is well suited for competition pistols, range work, and training where rapid target acquisition and clear tracking matter. The green reticle stands out in bright daylight while remaining crisp at lower settings, and the low-profile body keeps the optic compatible with common holsters and slide cuts using the RMR footprint. Holosun’s focus on practical innovation and dependable performance makes the 507COMP X3 a strong choice for shooters upgrading their pistol optics.
