The ALS® Shoulder Holster System provides heightened retention capabilities. With ALS, once the weapon is holstered it "locks" into place, securing it in all directions. Completely operable with the thumb, once the ALS device is instinctively released, a simple, straight out draw can be accomplished. Unique to this design is the ability to wear the holster in either a horizontal or vertical position. The harness is lightweight and cool and suspender clips keep the unit firmly in place.
