Safariland Model 6390RDSO ALS Mid-Ride Level I Retention Duty Holster for STI Staccato XC with SureFire X300U (MPN: 1335129)

Overview of the Model 6390RDSO ALS Mid-Ride Level I Retention Duty Holster

This Safariland 6390RDSO is built for duty use with optic-equipped handguns. The ALS automatic locking system secures the pistol on holstering and allows a straight-up draw after you release it. The mid-ride belt loop rides close to the body for comfort during long shifts.

Unlike the RDS series, the RDSO uses an open optic pocket that shields the red dot without a flip-up dust cover. SafariLaminate thermal-molded construction protects the handgun and sight area, and the suede lining helps prevent finish wear. It fits the STI Staccato XC 5-inch with a SureFire X300U. MPN 1335129.
