The DeSantis Facilitator is constructed of rigid .125 Kydex sheet and glass reinforced nylon for strength and durability and features our Redi-Lok trigger locking device. It can be worn strong side (butt rearward), cross draw(butt forward), or small of back (almost horizontal). The Facilitator is SLIM, which makes it much more concealable than the competition. The combat proven Redi-Lok makes this model very secure and snatch resistant. The Redi-Lok is a trigger locking device that is totally instinctual so almost no new training will be necessary. It is located on the inboard side so it's out of eye-reach of an adversary. DISCLAIMER: This product is not manufactured, authorized, endorsed, or warranted by GLOCK.
