The Holosun 507k X2 is the definitive multi-reticle optic for subcompact and micro-compact pistols. Designed specifically for concealed carry, it packs the legendary performance of the 507c into a slim, lightweight package. Featuring the Multi-Reticle System, Shake Awake technology, and incredible durability, this sight delivers a massive performance advantage without compromising concealability.
Key Features & Technology
Multi-Reticle System (MRS): The ultimate in flexibility. Choose the reticle that fits your needs: a precise 2 MOA dot, an ultra-fast 32 MOA circle for quick acquisition, or both at the same time without ever losing zero.
Solar Failsafe™: Your optic is always powered. The solar panel automatically supplements the battery and adjusts dot brightness based on ambient light, ensuring performance even if your battery fails.
Shake Awake Technology™: With motion-sensing technology, this optic automatically activates when it senses movement and powers down when stationary, extending the CR1632 battery life up to 50,000 hours.
Compact Design for Concealed Carry: The slimline design eliminates printing and snagging. With the 507k mounted, your pistol remains incredibly concealable, making it the perfect choice for firearms like the Sig Sauer P365, Springfield Hellcat, and Glock 43X MOS.
Durable Construction: Machined from 7075 T6 Aluminum with an IP67 waterproof rating, this red dot is built to withstand the rigors of everyday carry.
Mounting & Compatibility
This optic utilizes the **Holosun "K" series footprint**, which is a modified version of the RMSc footprint. This makes it a direct fit for many popular micro-compact slides. To understand the differences between the various footprints, read our detailed footprint guide here. For pistols with a different slide cut or no cut at all, our wide selection of Holosun-K pistol mounting plates provides a secure, non-permanent solution, giving you a perfect platform to get your 507k mounted.

FAQ
What is the difference between the 507k and the 407k?
The 507k and 407k are identical in size, shape, and footprint. The two key differences are the reticle and the solar panel. The 507k features the Multi-Reticle System (MRS) (dot + circle) and has a Solar Failsafe panel on top. The 407k has a single 6 MOA dot only and does not have the solar panel.
Will this optic fit my P365 / Hellcat / Glock 43X?
If your pistol slide is an "optics-ready" model cut for the Shield RMSc or "K" series footprint (like the Sig Sauer P365X/XL, Springfield Hellcat OSP, or Glock 43X MOS), it will often mount directly. If your slide is not milled, you will need an EGW pistol mounting plate that converts your rear sight dovetail to the correct mounting platform.
