Aye the trajectory is slightly lower. But weight in guns and weapons is the game is used to measure how fast/ how long you can run with the gun. The lowered trajectory doesn't have to do with weight, it's just a set trajectory, like that have frags or throwing knives, albeit the traectory is set differently
