Every class should get a sidearm and It should be quicker to take out your sidearm then to reload.
I cant count the amount of times I get pushed by someone mid reload and pull out my sidearm just to either not have one for some reason or be forced to wait the whole star wars saga to pull it out. It just doesn't make any sense.

It's roughly 3x-5x faster to deploy your pistol, than it is to reload primary weapon - Depending on the pistol and primary weapon.
Time perception warps under stress and anticipation, so people tend to feel like things take longer than they actually are. Wanting it NOW and not later.
