Use only these Fasteners and Retaining Clips for strap-to-strap & holster-to-strap connections.
 
Short Fasteners (above left) work best.  They provide enough clearance to allow 2 straps to move independently of one another, likewise, enabling movement between a strap and the holster.  Fifteen are included in the full kit.
 
Tall fasteners (above right) will be needed if straps will be double-stacked and then fastened to the holster, or if straps will be triple-stacked, but doing so isn't necessary and both may cause printing depending on body type/size.  Five of these are included in the Full Kit.
