Description
Compact micro red dot sight with versatile red reticle options and button lock technology, engineered for subcompact concealed carry pistols.
Note: This is the RED reticle version. For green reticle, see model HE507K-GR-X2.
Fast target acquisition starts with seeing your reticle clearly under any condition. The Holosun HS507K-X2 Red Dot delivers three reticle options in one compact optic, allowing you to switch between a precise 2 MOA dot for accuracy, a quick-acquisition 32 MOA circle for close-range speed, or both combined for maximum versatility. Lock Mode prevents accidental setting changes during carry, while the side-loading battery tray means you never have to remove the optic for power changes. Whether you’re carrying daily or training at the range, this optic keeps you ready with a 50,000-hour battery life and instant-on Shake Awake technology.
Key Features
- Multi-Reticle System (MRS): Toggle between 2 MOA dot only, 32 MOA circle only, or circle-dot combination by holding the minus button for three seconds—adapting your sight picture for precision shooting or rapid target acquisition
- Lock Mode Technology: Prevents inadvertent brightness or reticle changes during carry by holding the plus button for three seconds until the LED blinks, ensuring your optic stays configured exactly as you set it
- Side-Loading Battery Compartment: Replace the CR1632 battery without removing the optic from your slide, maintaining zero and eliminating downtime during battery changes
- Shake Awake with Adjustable Timer: Automatically powers down after 10 minutes of inactivity (adjustable to 1 hour, 12 hours, or disabled) and instantly reactivates with the slightest movement, extending the 50,000-hour battery life even further

Why We Carry It
The HS507K-X2 Red Dot represents a significant advancement in micro red dot technology, specifically addressing a common problem with carry optics: accidental setting changes. Lock Mode became so valued by professionals that it was incorporated across the entire X2 series. Combined with redesigned buttons positioned lower on the housing, this optic stays configured as intended throughout daily carry. The sight has earned recognition from multiple industry reviewers and maintains consistent positive feedback from both law enforcement and civilian users who appreciate its reliability and thoughtful engineering for concealed carry applications.
Frequently Asked Questions
What’s the difference between the HS507K-X2 and the HS407K-X2?
The HS507K-X2 features the Multi-Reticle System with three reticle options (2 MOA dot, 32 MOA circle, or both), while the HS407K-X2 has only a single 6 MOA dot. Both share the same housing, battery life, and Lock Mode feature.
Can I co-witness iron sights with this optic?
Yes, the HS507K-X2 Red Dot is designed with a sight height that allows co-witnessing with most factory iron sights on compatible pistols. The low-profile design maintains approximately the same line of sight as standard rear and front sights, making it suitable for concealed carry applications where you want backup aiming options.
How do I activate and deactivate Lock Mode?
To activate Lock Mode, hold the plus button for 3 seconds until the LED blinks once. In Lock Mode, both brightness buttons are disabled to prevent accidental changes. To deactivate, hold the plus button for 3 seconds again until the LED blinks, restoring full button functionality. This feature is particularly useful for duty carry or when the firearm is holstered for extended periods.
