The Holosun 507k X2 is the definitive red dot sight 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, the 507k X2 delivers a massive performance advantage without compromising concealability.

Key Features & Technology

• Compact Design for Concealed Carry: The slimline design eliminates printing and snagging, making it the perfect choice for pistols like the Sig Sauer P365, Springfield Hellcat, and Glock 43X MOS.
• Multi-Reticle System (MRS): Choose your ideal sight picture. Cycle between a precise 2 MOA dot, an ultra-fast 32 MOA circle, or both at the same time without ever losing zero.
• Shake Awake Technology™: With motion-sensing technology, the 507k X2 automatically activates when it senses movement and powers down when stationary, extending the CR1632 battery life up to 50,000 hours.
• Lock Mode: Lock the adjustment buttons to prevent accidental setting changes while carrying or in a holster.
• Durable Construction: Machined from 7075 T6 Aluminum with an IP67 waterproof rating, the 507k is built to withstand the rigors of everyday carry.

Mounting & Compatibility

The Holosun 507k X2 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 that are cut for this pattern. 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.
