Description
The Holosun HS507K X2 is one of the most popular micro-red dots on the market—and for good reason. Built specifically for slim, lightweight concealed-carry pistols, the 507K X2 delivers rugged durability, long battery life, and Holosun’s signature multi-reticle versatility in a compact package that punches far above its weight.
If you’re running a SIG P365, Springfield Hellcat, Glock 43X/48 MOS, or any other RMSc-footprint pistol, this optic is purpose-built for you.
Multi-Reticle System (MRS) – Versatility for Any Scenario
The 507K’s MRS lets you switch between:
-
2 MOA Dot
-
32 MOA Circle
-
Circle-Dot Combined
Whether you want lightning-fast acquisition or more precision for longer shots, you can choose the reticle that fits your mission.
Refined X2 Controls – Built for Real Carry Use
Holosun’s X2 upgrades were designed for concealed carriers:
-
Reduced button profile to prevent accidental activation
-
Lock Mode to keep your brightness setting locked in
-
Shake Awake so the optic powers on as soon as you draw
This is the kind of refinement that matters when the gun sits inside a holster 10+ hours a day.
Long Battery Life & Rock-Solid Durability
Powered by a single CR1632 battery with side access (no need to remove the optic to replace it), the 507K delivers up to 50,000 hours of runtime.
The 7075-T6 aluminum housing and Holosun’s proven electronics mean it’s ready for everyday carry abuse—sweat, bumps, recoil, and all.
Optimized for Slim Pistols
This optic uses the RMSc footprint, making it ideal for today’s most popular micro-compacts. Its short body and wraparound window were engineered to align perfectly with these smaller guns without sacrificing sight picture or durability.
