Dual wield for main weapon and sidearm at the same time. I find myself in situations where in CQB I need to use the sidearm fast but can't grab it while still holding the main gun. I know the habbit of releasing one and grabbing the other it will come with practice but still would be nice to have a possibility like that. Just for clarification I am right handed and use right hand setup but shoot with my left hand and eye from the main weapons. So the sidearm is really fast on draw and I shoot from the hip
