The Safariland 6390RDSO Staccato C 4" X300 STX Black holster is purpose-built for duty use with modern pistols equipped with red dot optics and a SureFire X300U light. Featuring Safariland’s proven Automatic Locking System (ALS), it secures the handgun the moment it is holstered while still allowing a smooth, straight-up draw once the release is deactivated. The open-top RDSO design protects the optic without a flip-up hood and rides on a mid-ride belt loop that keeps the pistol close to the body for a stable, consistent draw.

This right-hand, outside-the-waistband belt holster is tailored specifically for the Staccato C 4" with X300U, making it a strong choice for uniformed duty, training, or range work where retention and fast access matter. Its SafariLaminate construction and suede lining help shield the handgun and sighting system from wear during daily carry. Designed for red dot–equipped sidearms and professional use, it reflects Safariland’s long-standing reputation for thoughtful engineering and dependable holster performance.
