Hölster ADR MK 2 OWB Glock 17
MkII Holsters are a nice balance for those that want a slim holster.
The MkII holsters are fully compatible and will clear pistol mounted red dot sights, unless a thumb break is ordered.
The MkII features a user tune-able tension system which can either tighten or loosen the amount of passive retention the holster has. They can also be equipped with a level 2 thumb break rotating lock.
