Yeah it was the one hand cannon I absolutely wanted when they first showed it, such a beautiful gun. I got lucky and received it as my Nightfall reward last week. The only reason I haven't been using it a lot at the moment is that I've been trying to max out my Ice Breaker first for the fully upgraded exotic trophy/achievement as I was already pretty far along in its upgrades when I got Hawkmoon. Its time will come soon and I will cause the valleys of the four locales to reverb with its booming headshots! Then my Exo Hunter will be a "true" gunslinger...
