While I haven't shot one, I've looked into them, and multiple owners have made the out-of-the-blue comment that they are LOUD so take note of tac's advice!. They also have a hell of a muzzle flash too I guess. When it's designed to burn hot and fast out of the length of a carbine barrel, you end up having a lot of fine powder in open airspace shooting out of a blackhawk.
if you reload it, you could reduce that effect quite a bit. Ballistics are pretty heavily affected firing out of that barrel - still a great all around round, but you won't be getting that 1900FPS advertised on the box.
