This wedge can be mounted in a variety of ways, with screws or by adhesive. The screws are compatible with our “ALL FOR ONE” holster and many other manufacturers holsters with screw holes on the back side of the holster. The adhesive is a 3M command strip and allows for simple ability to test out the wedge on a holster you already have that is smooth sided. This is not a long term solution for mounting to a smooth sided holster and replacement with a more permanent adhesive or upgrading to our “ALL FOR ONE” is recommended.
