The ModWing is a standalone piece of concealment-enhancing hardware. It allows a user’s belt to apply additional leverage by rotating the holster and the grip of the gun towards the user’s body, creating better concealment and less user “printing” of the firearm and holster. It is available in two versions, standard and light-bearing. Interchangeable inserts allow the user to choose a strong or mild rotation, based on the user’s attire. The aggressive texture molded into the insert face increases the stability of the ModWing, in turn, the firearm and holster. Each ModWing kit comes complete with a Spine, 2 interchangeable Riser inserts, and Assembly Hardware. Due to the inserts being interchangeable, and the reversible spine, the ModWing is ambidextrous and can be configured for RH or LH carry This feature allows the thermoformer to limit their inventory while having to only keep a single item in stock.res.
