Bad Juju doesn't have 15 shots, it has 5 bursts. For a 5 shot weapon, it should hit harder. It should be able to kill with 5 shots (the entire mag) the same as guns designed for similar distances. I would suggest making the burst 2 bullets, instead of 3, upping the damage to equal the 3 round burst. The 2 round burst would also reduce recoil drift. Make the mag 16, to give a total shots per reload count to 8.
