*Please note that the Zip Slide is a minimalist belt-slide style holster. While it covers the trigger, it does not completely cover the rear of the trigger guard area. The belt-slide design has proven safe on many holsters for several decades with correct use, however if you are uncomfortable with this aspect of the design the Zip Slide may not be the best holster for you.
