Sonic shotgun could use a visual effect for it's secondary fire range and if it hit an infected

I know the sonic shotgun’s secondary fire got better prediction but there are times when it looks like it should’ve pushed back an infected. I can’t tell the range for the secondary fire so I think there should be a visual effect showing the range of the sonic shotgun’s alternate fire range. Also when I had it equipped in the plaza I noticed I only got 10 alt fires despite it not being in the virus game mode. It shouldn’t have ammo in the plaza and the alt fire should be able to push other players who have PVP enabled in the plaza as well.
