Holosun HS407C X3 Red

Estimated Ship Date 2/25/26

The Holosun 407C X3-RD2 modernizes the trusted 407C platform with a reinforced housing, updated brightness control, and a crisp 2 MOA red dot built for everyday carry, duty use, and range performance. Designed around the RMR footprint, it delivers a low-profile optic that stays fast and simple on the slide. Automatic brightness from a forward-facing photodiode works with Solar Failsafe to keep the dot dialed in as light changes, while manual controls with memory and lockout give shooters full command when needed. Powered by a side-loading CR1632 battery rated up to 100,000 hours, and backed by Shake Awake, IP67 waterproofing, and 5000G vibration resistance, the HS407C-X3-RD2 is built for real-world reliability without extra bulk.
