Holosun HS507K X2 – Compact Reflex Sight for Subcompact Pistols

The Holosun HS507K X2 is an open reflex red dot sight specifically designed for subcompact pistols, making it a top-tier choice for concealed carry and EDC users. Built with a durable 7075-T6 aluminum housing and a minimal footprint, the 507K X2 delivers rugged reliability in a compact, lightweight package.

This upgraded version includes Lock Mode, which disables the side buttons to prevent accidental adjustments—a welcome feature for concealed carry or duty use. The sight also features Holosun’s signature Multi-Reticle System (MRS), allowing you to switch between a 2 MOA dot, a 32 MOA circle, or a combination of both for a customizable sight picture.

With Shake Awake™ technology, the optic powers on instantly with motion and conserves battery during periods of inactivity. A side-mounted CR1632 battery tray makes battery replacement quick and easy, while maintaining zero. The HS507K X2 uses Holosun’s “K” footprint and is a direct fit for optics-ready pistols like the P365X/XL—others may require an adapter plate.
