The Holosun HE407K X2 is a compact open-emitter pistol green dot for concealed carry and slim handgun platforms. On the Holosun K (RMSc) footprint, it sits low for a snag-free fit on micro-compact slides, with a precise 2 MOA green dot — many shooters find green easier to pick up in daylight.
The X2 adds Lock Mode against accidental changes and Shake Awake for instant readiness and long battery life (up to 50,000 hours on a side-loading CR1632). Durable aluminium housing, 12 settings (2 NV).
