Frequently Asked Questions (FAQ)

What footprint does the Holosun HE407COMP use?
The Holosun 407COMP uses the industry-standard Trijicon RMR mounting footprint. This makes it highly compatible with a wide variety of aftermarket pistol slides, optic plates, and adapter systems.

Why choose a 6 MOA red dot for competition?
A 6 MOA dot is ideal for speed-focused shooting disciplines because it is large enough to pick up quickly during rapid draws and target transitions. In USPSA, IDPA, or Steel Challenge, that faster visual confirmation can translate directly into reduced stage times.

What battery does the Holosun 407COMP use?
It operates on a single CR1632 battery. Thanks to the convenient side-loading battery tray, you can easily swap the battery without removing the optic from your pistol or re-zeroing your sight.

Does the Holosun 407COMP have Shake Awake technology?
Yes. The optic automatically shuts off during periods of inactivity to conserve battery life and instantly powers back on to your last brightness setting when movement is detected. This is especially valuable for duty or defensive setups where readiness matters.

Is this reflex sight good for USPSA or IDPA?
Absolutely. The HE407COMP was specifically designed for competitive shooting. Its oversized window allows for faster sight acquisition during rapid transitions, making it a popular choice for USPSA, IDPA, and Steel Challenge competitors.
