Video below shows a custom pistol made by Bunny Workshop that uses the Guns Modify Limited Edition SAI RMR Slide Set, Chris Costa Version. If interested you can contact them if they can make a complete custom work for you but you will need to hurry as they only have three slides left in case you want to put one for yourself. Remember that this is a limited edition product.

The Costa Leg Rig gets a padding for more comfort by HSGI... "The Padded Drop Leg Panel combines the comfort of the original Costa Leg Rig with the versatility of our Mini Modular Leg Panel. 3 rows and 6 columns of MOLLE/PALS webbing are efficiently sewn on top of HSGI's™  popular padded mesh platform system. This gives a cool, secure and comfortable fit that can be customized with any configuration of TACO pouches.
