I think, in regards to performance, it works just fine, but it's glimmer collection perk is pretty lackluster. Having a CHANCE to pick up 3-4 glimmer ONLY for a primary ammo drop doesn't really seem worthy of an exotic item. It's a wonderful idea, but it could use some work. I think it could use a buff to either increase the amount of glimmer gained or expand the glimmer chance to all types of ammo pickups.
