The Holosun 407k X2 is the definitive optic for shooters who value simplicity, speed, and reliability in a micro-compact package. Purpose-built for concealed carry, the 407k features a crisp, clear 6 MOA dot that is incredibly easy to acquire under pressure. It combines this user-friendly reticle with Holosun's legendary durability, Shake Awake technology, and a slimline profile perfect for everyday carry.
Key Features & Technology
Crisp 6 MOA Dot: The clean, simple 6 MOA dot is the core of the 407k. It is large enough for extremely fast target acquisition at close ranges, making it an ideal choice for defensive pistol use.
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.
Shake Awake Technology™: With motion-sensing technology, the 407k 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 407k is built to withstand the rigors of everyday carry.
Mounting & Compatibility
The Holosun 407k 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.

Holosun 407k FAQ
What is the difference between the 407k and the 507k?
The 407k and 507k are identical in size, shape, durability, and footprint. The only difference is the reticle. The 407k features a simple, clean 6 MOA dot, which many shooters prefer for its speed and simplicity. The 507k features the Multi-Reticle System (MRS), which allows the user to switch between a 2 MOA dot, a 32 MOA circle, or both.
Will the Holosun 407k fit my P365 / Hellcat / Glock 43X?
If your pistol slide is an "optics-ready" model cut for the Shield RMSc or Holosun K footprint (like the Sig Sauer P365X/XL, Springfield Hellcat OSP, or Glock 43X MOS), the 407k 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 a Holosun K mounting platform.
