Overview

The Holosun 507K X2 brings all the features of the larger 507C to the Shield RMSc footprint used by slim pistols like the SIG P365 and Glock 43X/48 MOS. 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 the same robust construction as its larger siblings. Solar failsafe and Shake Awake are both present, providing exceptional battery life that typically exceeds the rated 50,000 hours. The side-loading battery allows changes without unmounting the optic.

The Shield RMSc footprint has become the standard for slim optic-ready pistols, and the 507K is the overwhelming choice in this category. The combination of multi-reticle options, solar backup, and proven Holosun durability makes it difficult to recommend alternatives for slim pistol use.
