The Holosun HS407K X2 is a compact open-emitter pistol red dot built for concealed carry and micro-compact slides. It runs on the Holosun K (RMSc) footprint for a low, snag-free fit, with a 6 MOA dot that's quick to find under stress.
The X2 upgrades add Lock Mode to stop accidental setting changes and Shake Awake motion activation for instant readiness and long runtime — up to 50,000 hours on a side-loading CR1632. Durable aluminium housing, 12 brightness settings (2 NV), IP67-rated.

Frequently Asked Questions
What footprint is it?
The Holosun K footprint, which matches the Shield RMSc pattern used by most micro-compact optics-ready slides.
6 MOA or 2 MOA dot?
The 6 MOA dot here is bolder and faster for close-range/EDC; the HE407K offers a finer 2 MOA dot for more precision.
Does it have Shake Awake?
Yes — it sleeps when idle and wakes on movement, giving up to 50,000 hours of runtime.
