It's nice to have when you are doing something with the juggler modifier or if you can't get ammo during a boss fight. And if it had regeneration along with a standard mag, it would probably regen slowly like Invective does. The impact is pretty decent considering it doesn't have a horrendously slow rate of fire. The gun's magazine has max sniper capacity (six shots). I'll admit that the kick sucks, but you eventually get used to it and can fire off shots quite rapidly. 8k kills and still loving it.
