I'm not their target customer, but at least it looks somewhat "done up" compared to a normal Glock. At least there is something you can see that is different and probably deserving of the additional cost.
Conversely, I can't figure out why the Glock fans.. are Glock fans. Glock will add or remove finger grooves or make the grip longer (on a gun meant for concealment), call it a new generation, and the fanbase busts a nut and can't slap down $500 quick enough. Absolutely kooky.
