Overview

The Holosun 507C X2 has become the default recommendation for pistol red dots, offering premium features at a mid-tier price. The multi-reticle system (MRS) allows shooters to select between a 2 MOA dot for precision, a 32 MOA circle for speed, or both combined for fast acquisition with precise aiming. The circle helps shooters find the dot faster, especially under stress.

The 507C features Holosun's solar failsafe technology - a solar panel that powers the optic in bright conditions, extending battery life significantly. The Shake Awake function puts the optic to sleep when stationary and wakes it instantly upon movement, balancing always-ready operation with battery conservation. In practice, batteries last years with normal use.

Built on the RMR footprint, the 507C fits any slide cut for the Trijicon RMR, making it compatible with the vast majority of optic-ready pistols and aftermarket slides. The side-loading battery compartment allows battery changes without removing the optic - a significant improvement over bottom-loading designs. Durability has been proven through thousands of rounds across countless users.
