It's garbage for anything besides boss fights. Rate of fire is so slow enemies move or shield before your 2nd or 3rd shot will even go off. It shouldn't take me 3 trigger pulls to fire 1 shot... it's barely faster than NLB. Bungie doesn't really define their definition of "rapidly", but from my experience with the Black Hammer, it's just about as fast as the gun can fire. A second or two longer between shots and I get no reloads.
