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.
