There are too many useless similar weapons

the auto guns are all similar rubbish, most laser guns are similar too.
we need shotguns, snipers, (sub)machines and revolvers.
shotgun and revolver have so little ammo, meanwhile other guns can shoot more than 200 times.
and revolver has a very-stupid reloading, I wonder if FS’s men use it in level 3 or higher?
