The Safariland Model 6390RDS ALS Mid-Ride duty holster (brand part no. 1208020) is built specifically for Sig Sauer P320 RX pistols carrying a mounted red dot sight and a rail-mounted light, using Safariland’s ALS (Automatic Locking System) for retention. Safariland designs the ALS as an internal locking device that retains the firearm in every direction with no external straps or snaps to manage, engaging automatically the moment the pistol is holstered. The lock releases with a simple thumb motion, after which the pistol draws straight up and out. A low-ride belt loop sits 1.5 inches lower than a standard mount for a closer ride to the body, and a suede lining protects the mounted optic and the pistol’s finish. Among holsters & gun leather, this 6390RDS configuration favors duty carriers running a red-dot-equipped, light-bearing P320 RX who want thumb-operated retention.
