Description
The Holosun HS507K X2 is a purpose-built open-reflex sight engineered specifically for subcompact and micro-compact concealed carry pistols. Housed in a rugged 7075-T6 aluminum frame with a black anodized finish, this optic delivers full-size performance in a footprint small enough to disappear on your everyday carry pistol without adding bulk or snagging on the draw.
Compact, Purpose-Driven Design
With a viewing window measuring approximately 0.58″ x 0.77″ and a weight of just about 1 ounce, the HS507K X2 is built around Holosun’s K-series footprint, making it a natural fit for a range of subcompact and micro-compact slides — many direct-fit, with adapter plates available for others. The low-profile housing protects the emitter and lens without adding unnecessary height or width, keeping your holster fit tight and consistent.
Multi-Reticle System (MRS)
At the heart of this optic is Holosun’s Multi-Reticle System, giving you the flexibility to select between a precise 2 MOA red dot for deliberate, accurate shot placement, a 32 MOA circle for blazing-fast target acquisition up close, or a combined circle-dot reticle that blends both for versatile use across defensive distances. Because all reticle options are projected from the same emitter, switching between them requires no re-zeroing — your point of impact stays true no matter which reticle you choose.
Reliable Illumination and Battery Life
The HS507K X2 uses Holosun’s Super LED technology to produce a crisp, clean red reticle that stays visible across a wide range of lighting conditions. With 12 total brightness settings — 10 daylight settings plus 2 night-vision-compatible settings — you can dial in the exact intensity you need, whether you’re training in bright sunlight or operating in low light. Battery life is rated up to an impressive 50,000 hours on a single CR1632 battery, and the side-mounted battery tray allows for quick replacement without ever having to remove the optic from your slide, preserving zero.
