The Model 6390RDS (brand part no. 1208018) from Safariland is built for the Sig Sauer P320 RX 9 carrying both a factory-mounted red-dot optic and a weapon light. The RDS cut clears the optic while the Automatic Locking System (ALS) handles retention, an internal lock that engages automatically the moment the pistol is holstered, with no straps or snaps involved. It’s fully thumb-operable, releasing into a simple straight-up draw, and the mid-ride belt loop keeps the rig riding close to the body. A suede lining protects the optic and finish through repeated use.
