This tactical holster features the SLS (Self Locking System) rotating hood. With no snap, the SLS allows for a smoother single-motion draw and greater protection against attempted weapon takeaways. The hood can only be released by being simultaneously pushed down and rotated forward and actually becomes more secure when upward force is applied. It is also far less likely to release accidentally than conventional thumb break snaps. Molded sight track and soft SafariSuede protect the gun's sights and finish. The Model 6004 features a standard double leg strap and leg shroud with mounting holes for optional accessories. The rugged STX finish protects the gun against scrapes, scratches and dents.
