Holosun 507K X2

The Holosun 507K X2 brings the larger 507C's multi-reticle system to the Holosun K footprint used by many slim pistol cuts and adapter plates. The multi-reticle system offers the same 2 MOA dot, 32 MOA circle, or combination, allowing shooters to choose their preferred aiming solution.

The compact size doesn't sacrifice durability. The 507K uses 7075 aluminum, IP67 sealing, and 5000G vibration resistance. Shake Awake and a side-loading CR1632 tray provide long battery life and let you change batteries without unmounting the optic.

The Holosun K footprint is closely related to Shield RMSc, but it is not identical on every slide. Some pistols mount the 507K directly, while standard RMSc cuts may require the correct adapter plate or permanent recoil-lug modification. The combination of multi-reticle options, side-loading battery, and proven Holosun durability makes it difficult to recommend alternatives for slim pistol use.
