If i made it one key, you wouldn't be able to switch to a different gun with a different hand, its meant to multitask guns, like lets say using the pistol for midair microadjustments and the sawnoff for heavy recoil, or sniper for ranged dummy shots that project you upward and then you again microadjust with the pistol.
