Quickshot is the exact same model, too, only sans the holoscreen thingie. And I guess it's not a bad thing, two screens would look silly and be a bit unwieldy.
That said, two Black Nebulas would be great for (if only) one thing: the shooting sound.
True! But, the coloring is different. A big "no no" for me
By the way, I keep hearing that the Black Nebula sounds great. What does it sound like? Is it a "deep sound" like the Elegant Modified Blaster Pistol or like the X-11 Huntsman Pistol?
