The Combat Master is a professional-grade belt holster hand-molded to fit specific handguns. Its traditional high-riding pancake-style design places the belt slots on either side of the holster, pulling the handgun tight to the body and making defensive handguns disappear under even light clothing. It features an open top with firing grip accessibility for speed. The twin belt slots fit belts up to 1.75" wide. Fits 4" barrel Ruger Security-Six, Service-Six, Speed-Six; 4" barrel S&W 10, 19, 66 K-Frame; 4" barrel Taurus 66.
