This holster features the Self Locking System (SLS) rotating hood design and the 567BL belt loop to fit 1.5 in. (38 mm) to 1.75 in. 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. Gun fit: H&K HK45.
