The Holosun 407K X2 is an open-reflex red dot designed specifically for slim-profile concealed carry pistols. It features a 6 MOA dot and uses Holosun’s Super LED for extended battery life—rated up to 50,000 hours on medium settings. The sight also includes Shake Awake for automatic on/off activation and Lock Mode to prevent accidental setting changes.

Constructed from 7075 aluminum and hardcoat anodized, the 407K X2 is compact, lightweight, and durable. It uses Holosun’s K footprint, a modified RMSc pattern that fits a variety of slimline pistol slides, including direct fitment to the SIG P365X/XL without adapters. This model provides parallax-free operation and unlimited eye relief in a simple, rugged package.
