Granite Ridge's Take

The Holosun 407C X3 updates the popular 407C platform with a reinforced 7075-T6 aluminum housing, revised automatic-brightness control and the same straightforward single-dot concept that made the earlier model popular. It uses a crisp 2 MOA dot, RMR footprint, side-loading CR1632 battery, Solar Failsafe and Shake Awake, with red, green and gold reticle versions available. If you want a simple full-size pistol optic without the multi-reticle system of the 507C X3, the 407C X3 is the more streamlined choice.

Buying & Compatibility Notes

The 407C X3 uses an RMR footprint and a single 2 MOA dot. It is designed for full-size pistol applications and is a natural comparison against the 507C X3. Confirm whether your handgun mounts an RMR-footprint optic directly or requires an adapter plate.
