This clip goes down BEHIND the belt and then hooks up at the bottom preventing the holster from drawing out with the gun. The advantage to this clip is that it is more discreet than the SnapLok, but by putting the weight on the pants instead of the belt, it tends to want to ride down with heavier guns and is not as stable.
The most common option is for folks to order a set of J-Hooks to go with thier SnapLoks. We make this very easy by this being the default option and a pair of these is only $10.00 if ordered at the time you order your SuperTuck®. This means you would get both the SnapLoks and a pair of J-Hooks and decide which you liked best or mix and match. Charges for order applied at time of purchase.
