The 507K X2 is an open reflex optical sight designed for subcompact pistol applications. The 507K X2 improves on previous the version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.
Additional features include Holosun’s Super LED with up to 50k hour battery life, Multi-Reticle System, and Shake Awake. The durable housing is made from 7075 Aluminum, uses Holosun’s K footprint, and houses the 1632 battery in a side-mounted tray for easy replacement when needed. The 507K X2 is a direct for P365X/XL, and requires an adapter plate for slides with a four-boss interface.
Granite Ridge's Take
The Holosun 507K X2 adds a multi-reticle system to Holosun’s compact K-footprint pistol format. It is intended for narrow carry pistols where a full-size optic would be unnecessarily wide, while still giving the shooter more reticle flexibility than the simpler 407K X2.
Buying & Compatibility Notes
Good fit for compact pistols when an open emitter and multi-reticle system are preferred. Compare with EPS Carry for enclosed-emitter protection.
