One more thing would make it tremendous - Alien Gear Holsters ShapeShift Glock Core Carry Holster Pack

Very complete kit. Great range of carry styles and adjustments for each. The only thing that would make it really tremendous, would be to include a second half shell. Then you would have a tuckable IWB or an appendix carry IWB (half shell), and, with the remaining parts, a way to move your weapon to a separate, complete holster in one of the full shell configurations without dismantling the holster. Then just swap out the weapon from you IWB into a mounted holster by your bedside or under desk. Without that option, you end up with a wasteful box full of unused parts. It's still outstanding, though.
