The Holosun 507K red dot is a compact, open-emitter micro optic purpose-built for concealed-carry and subcompact pistols, delivering a balance of speed, precision, and durability in a slim, carry-friendly form factor. Designed around Holosun’s K-series footprint (a modified RMSc pattern), it integrates seamlessly with popular micro handguns like the Sig P365 and Glock 43X MOS. At its core is the Multi-Reticle System, allowing shooters to switch between a precise 2 MOA dot, a fast-acquisition 32 MOA circle, or a combined circle-dot reticle for maximum versatility. Powered by Holosun’s Super LED, it offers up to 50,000 hours of battery life, complemented by Shake Awake technology to preserve power and ensure readiness. Built from durable 7075 aluminum with a side-loading CR1632 battery tray and Lock Mode to prevent accidental adjustments, the 507K is engineered for reliable everyday carry performance in a lightweight, low-profile package.
